13. Toshiki Murakami and Fujio Tsumori, Encoded actuation of miniaturized flexible magnetic pillars, International Conference on Materials & Processing 2022, 2022.11, In recent years, magnetically actuated pillars have been attracted by researchers. The structures are mainly inspired by organisms in nature, cilia. These organisms are used for many purposes, such as swimming, locomotion, pumping, and transportation. The magnetically actuated structures which mimic the natural creature can be used for various engineering applications. Microfluidic devices and micro transportation systems are typical examples. of the magnetic material is useful for these purposes since they have high mechanical property and could be actuated wirelessly. However, there are some issues to mimic the natural cilia motion; the movement pattern is simple and limited; and the size is much larger than the natural ones. In this work, we developed 2-dimensional magnetic pillar arrays composed of silicone elastomer and magnetic particles to be controlled by coils set in 2-axial directions. We also tried to fabricate micrometer size pillars using polycarbonate tracked etched membrane..
14. Ryoma Shiraishi and Fujio Tsumori, Micropatterning of Magnetic Properties on Gel Sheet for Soft Robotics
, International Conference on Materials & Processing 2022, 2022.11, In this work, we propose a new magnetic gel material for soft robotics. Micropatterning of magnetic properties can be printed on a gel sheet to design deforming of the sheet material. We selected a tough gel material, which are known as double-network gels (DN-gels), as a base material and dispersed a magnetic powder. The proposed material showed not only high strength and large elongation but also high anti-cutting strength. Authors also developed a new process for a magnetic micro patterning process for this material using local heating by laser. The resolution of the printed pattern was finer than reported conventional magnetic soft actuators. We performed cutting and tensile tests of the gel material and showed mechanical properties. We also tried to scan laser on a magnetic gel sheet for micro patterning of the magnetic anisotropy..
15. Kazuhiro Yamada and Fujio Tsumori, Development of a multi-nozzle 3D printing system for metal-ceramics composite structures
, International Conference on Materials & Processing 2022, 2022.11, This study focuses on the development of a 3D printing system for multi-material dispensing nozzles that can fabricate multi-material products by combining ceramic and metal materials. In various structural and functional applications, zirconia components could improve performance by bonding ceramic to metal so that we employed zirconia and stainless steel for this experiment. We attempted to employ powder injection molding compounds as print materials both for the ceramic and metal powders. To facilitate handling in the desktop printing system, we mixed synthetic wax and rapeseed oil as binder material. The use of rapeseed oil allowed for lower printing temperatures and the use of alcohol for debinding prior to sintering. The goal of this work is to fabricate composite structures of stainless steel and zirconia using the developed 3D printing system..

Magnetic beads were precisely actuated as a rotator, which could be used for a pumping system. The magnetic beads were set on a round base which periodically embedded magnetic beads on the surface, and were actuated by magnetic interaction force excreted by a rotating magnetic field. We show theoretical background and demonstrate actuation using a 3D-printed sample. Also, we tried to use the present system as a pumping system..

63. Kazuki Tokumaru, Kazuhiro Yonekura, and Fujio Tsumori, Influence of Scale on Interfacial Pattern of Multilayered Imprinting, The 12th Asian Workshop on Micro/Nano Forming Technology, 2019.08, Nano Imprint lithography (NIL) is a technique that transfers a fine mold pattern to the surface of a work material. NIL is an excellent technology in terms of high productivity, accuracy, and resolution. Recently, a technology called multilayered imprint has been developed in which NIL is applied to processing of a multilayered material. In this process, it is possible to form not only surface of a workpiece, but also an interfacial pattern between the upper layer and the lower layer simultaneously. Using this technology, processing of functionally graded materials and fabrication of complex patterns using a sacrificial layer have been studied. Control of interface shape is necessary in multilayered imprint. The interface pattern can be controlled by the deformation characteristics, initial thickness, and so forth. In this research, we compared the interfacial pattern changes of imprinted multilayered materials in milli- and microscales. For multilayered imprint using multiple materials, it is important to know the flow of the resist and its dependence on the scale. If there is similarity in the relationship produced by the scale on the imprinted samples, a process design with a number of feedbacks could be realized. It also becomes easier to treat structures in the millimeter scale for the experiment. In this study, we employed micropowder imprint (μPI) for multilayered material imprint. A compound sheet of alumina powder and polymer binder was used for imprint. Two similar experiments in different scales, micro- and millimeter scales, were carried out. Results indicate that the interfacial patterns of micro- and millimeter-scale-imprinted samples are similar..

110. 徳丸和樹, ハント戴紋, 津守 不二夫, 工藤健太郎, 品川 一成, レーザ加工とインプリント加工の複合プロセスによるセラミック3次元マイクロ流路の開発
, 第34回「センサ・マイクロマシンと応用システム」シンポジウム, 2017.11, 本研究では,3次元構造のセラミックマイクロ流路を作製する新しい方法を提案する.本研究では,マイクロ流路の上面に波状の構造などの表面パターンを形成することにより,流路上面の表面積拡大と流路長さの延長を行う.セラミックスマイクロ流路は,樹脂に比べて耐熱性,耐食性,耐薬品性,強度などに優れているため,従来の樹脂製流路では使用できない,高温または過酷な環境で使用することができ,高効率の熱交換器,固体酸化物燃料電池の電解質,燃料改質器などのような製品への適用が可能である.
セラミックマイクロ流路の作製のために,本研究ではμPI(Micro Powder Imprint)法とレーザ加工を組み合わせた加工プロセスを開発した(1).図1にマイクロ流路形成プロセスの概要を示す.まず,ホットエンボス用コンパウンドシートとして,セラミック粉末と樹脂を混合する.続いて,レーザ加工により微細な流路パターンに形成された犠牲層を2枚のコンパウンドシートで挟み込み,インプリント処理を行う.その際,犠牲層はコンパウンドシートの表面に沿って変形する.最後に,脱脂・焼成工程において,樹脂および犠牲層を分解し,セラミックのみからなる微細な流路を得た.
研究の結果,コンパウンドシートと犠牲層は異なる成形特性を有していた.これは,流路の形状が,材料のインプリント条件または成形性に影響されることを意味する.本研究では,コンパウンドシートの材料比やプレス温度を変えることにより,流路の成形性を制御した.図2に(a)40℃および(b)100℃でインプリントされた試料の断面画像を示し,加圧温度と流路の振幅の関係を図3に示す.これらの結果から,温度の影響を把握し,流路の形状制御を行った.
図4は,焼結後のアルミナマイクロ流路のX-CTスキャンによる(a)断面および(b)外観画像である.マイクロ流路の高さは約20μmであり,幅は約40μmであった,X-CT画像からはアルミナマイクロ流路内のクラックなどの欠陥は見られない.図5は,水中での空気を用いた流動試験中のマイクロ流路の出口の写真画像である.流路の入口から送られてきた空気が出口から出ており,微小流路の表面から空気の漏れがないことが確認された.

実験にはPDMS(Poly-dimethyl-siloxane; Sylgard184)とカルボニル鉄粉(平均粒径4.36 μm)を用いた.粉末が1 mass%になるように混合・分散し,プラスチック容器に注いだ後,遠心分離機により粒子を沈降させ,容器底部に粒子層を生成した.この際,容器内に材料を装填する深さを変えることで,最終的な粒子層の厚さを変化させたサンプルを得た.その後,水平方向に磁場を印加し粒子鎖構造を生成し,PDMSを硬化した.得られたサンプルに対し所定の一軸ひずみを面内に加えた際,表層部にしわが観察された.
図2に圧縮ひずみを与えた際の粒子層厚さとしわ周期との関係を示す.また,図3に,しわが生成するまでに与えたひずみ(臨界ひずみ: εc)を示す.ここでは圧縮方向を粒子鎖構造に対して平行,垂直の2種類のデータを示している.均質材料では,周期は薄膜厚さに比例するが,ここでは非線形の関係が見られた.粒子の沈降時に厚さ方向になんらかの分布が生成していることが予想される.また,しわの周期は粒子鎖の向きにはほとんど影響していないことがわかる.一方,図3に示したしわの生成する限界ひずみ量では,特に層が薄い場合に大きな差が見られる.
次に粒子鎖構造の異方性(粒子鎖の向き)をパターニングした例を示す.紫外線硬化型PDMS(KER-4690,信越化学)を用い,マスクを用いたパターニング結果を図4に示す.また,このサンプルを圧縮した様子を図5に示す.与えたひずみ方向と粒子鎖構造が平行な領域にのみしわが生成しており,局所的なしわの生成が制御できることが示された.

天然の繊毛の運動では,繊毛が直線的な形状で変形する有効打,曲線的な形状で変形する回復打の2つの異なるストロークを繰り返している.この非対称運動により,低レイノルズ数領域で流れを作り出している.著者らは磁性粒子を分散させたPDMS製の人工繊毛を回転磁場下で駆動させることでこの振る舞いを模倣できることをすでに報告している(1).図1に,人工繊毛の動きの例を示すが,この例では,人工繊毛は垂直な2次元平面内で運動を行っている.しかしながら,近年,詳細な繊毛の観察により自然界の繊毛が3次元的な運動を行っていることが分かってきた.有効打では繊毛は真っ直ぐな構造になり,回復打では表面に沿うような運動を行っている(2).また,計算機による最適解析では結果として同様の運動が得られている(3).
このような3次元的な動きを行うため,磁場印加時に図2のような実験のセットアップを用意した.軸方向に垂直に磁化された永久磁石を用意し回転させる.磁石の真下にある点Aは既報において人工繊毛を設置した位置である.この位置では垂直平面内を回転する磁場が得られる.今回の報告では,右横と右斜め前方の点Bおよび点Cに人工繊毛を設置した.図3に磁石を回転させたときの磁束の変化を示す.この単純なシステムを使用して,回転軸を傾斜させた回転磁場を容易に印加することができる.
人工繊毛の作製には,シリコーンゴム材料(Ecoflex00-30,Smooth-on)およびカルボニル鉄粉末(径:4.36 μm)を使用した.樹脂材料と磁性粒子を混合し,型に充填し,硬化させピラー状に成形した.柱の高さは3 mm,厚さは150 μmとした.繊毛のスナップショットの一例を図4に示し,繊毛の先端の軌跡を図5に示す.B点およびC点の両方において3次元的な運動が観察された.点Bと点Cでは挙動が異なり,点Cでの動きは,報告されている天然の繊毛の動き(2)と似た挙動が得られた.今後,この人工繊毛を用いPIVによる流れ場解析を行う予定である.

, Micro TAS 2017, 2017.10, We propose a new three-dimensional (3D) printing system for magnetic elastomer, which is composed of photo curable resin dispersed with magnetic particles. The obtained structure is magnetic and flexible so that they can work as an actuator by changing the applied magnetic field. During the curing process, a magnetic field is applied to set magnetic anisotropy at the curing portion, and we can design the motion of the actuator using this anisotropy. It means that we can not only print the 3D-structure but also print the deformation of printed actuator..

Kazuki TOKUMARU, Fujio TSUMORI, Shinagawa Kazunari, Fabrication of Wavy-Electrolyte for SOFC by Micro Imprint Process, 13th International Conference & Exhibition on Ceramic Interconnect & Ceramic Microsystems Technologies, 2017.04, Solid oxide fuel cells (SOFC) are fuel cells made of ceramics. SOFC have the highest efficiency among various kinds of fuel cells. They are mainly used for relatively large scale power source such as power plants. SOFC is expected to be a new main generator; however, energy density is not high and downsizing is also required to be more popular. To enhance the energy density of SOFC, we developed a SOFC with wave-electrolyte layer. As a wavy electrolyte has larger reacting area than a flat-electrolyte, higher energy density could be obtained. We propose a new method to form a wavy electrolyte layer in this work. The aim of our study is to develop a processing method of the thin and wavy YSZ electrolyte for SOFC. Our proposed process is named micro powder imprint (µPI) with multi-layer imprint process that is useful to fabricate micro scale pattern on a ceramic sheet such as an electrolyte layer of SOFC. The µPI is inspired by nano imprint lithography (NIL). NIL is a process to transcribe a nano-pattern on a resin film using a mold, and has been proposed by S. Y. Chou. The process can produce a fine pattern on the surface in high resolution, and is mass-productive. NIL is a process for polymer as a work material, while µPI is a process for inorganic materials. The starting material for µPI is a compound sheet containing material ceramic powder and binder consisting of thermoplastic resin. Fine pattern can be transcribed on a compound sheet by pressing with a mold as similarly with NIL. After imprinting, the resin in the compound is decomposed by heating, and inorganic powder is bonded together during the following sintering step. Authors already have reported fabrication of electrolyte sheet which has micro pattern on one side of the sheet by µPI In this study, we propose a method to form not only an electrolyte sheet but also an anode layers at a one time. Two different sheets were stacked into one sheet as a multi-layer sheet for the µPI process to form a wave-type compound sheet. We could control interface pattern between electrolyte and anode layers by changing mechanical property of each starting compound material. Next the formed layered sheet was sintered subsequently. Generally, it is not easy to sinter two kinds of materials at same time, because different shrinkage rate causes distortion. In this work, we tried several conditions to obtain sound sintered samples. As a result, the SOFC unit cell with wavy-electrolyte was fabricated without any cracking and bending. It is noted that the anode layer was formed at the same time. After adding the cathode layer, we succeeded to prepare a complete cell for testing power generating. The area of interfaces between anode and electrolyte was increased to over 120 % from flat electrolyte. This means a reaction surface area increased and higher efficiency would be expected. By using unit cells with wavy-electrolyte developed by our study, improvement of power generation efficiency of SOFC by simple processing can be expected..

In this work, relatively large and complex shaped parts were prepared thorough MIM. In order to decrease the deformation of sintered parts, powders of different sizes were mixed. The effect of powder particle distribution and powder loading on the distortion of complex shaped compacts were investigated and evaluated. As smaller the particle size of mixed powder, tap density of powder were decreased. However, sintered density and shrinkage were increased. Although high powder loading increased the viscosity during the injection molding, decreased the shrinkage of sintered compact. From these results, smaller deformation of the large and complex shaped parts could be realized by using mixed powder with smaller particle and higher powder loading..

Kazuki Tokumaru, Fujio TSUMORI, 工藤 健太郎, Toshiko Osada, Hideshi Miura, Development of corrugated ceramic sheet for SOFC electrolyte by micro imprint process, 3rd International Conference on Powder Metallurgy in Asia, 2015.11, Yttria-stabilized zirconia (YSZ) has been used for an electrolyte of solid oxide fuel cells (SOFC). To enhance the efficiency of SOFC, we developed a corrugated, or wavy-shaped, YSZ sheet for the electrolyte. As the corrugated sheet has larger surface area than a flat-type sheet, higher energy density can be obtained. We have proposed micro powder imprint (µPI) with multi-layer imprint process to fabricate micro scale pattern on both surfaces of a thin YSZ sheet. The µPI is a combined process of nano imprint lithography and powder metallurgy; the resolution is high, and the process is mass-productive. We can use various inorganic materials as powder materials. In this work, we selected a compound material containing YSZ powder and a binder consisting of thermoplastic resin as a starting material. The compound sheet was prepared by tape casting from slurry. Next, the compound sheet was stacked on a silicone rubber sheet and was imprinted by a fine-patterned mold. The silicone rubber was so flexible that micropatterns on the both sides of the compound sheet was obtained after imprinting. For the further improvement of the manufacturing method for a wave-type YSZ electrolyte, higher mold precision, and the process parameters such as temperature and pressure control, are important factors. In the present work, we used laser machining for mold manufacturing, and the process condition of µPI and the heat program of debinding and sintering were also optimized. As a result, a wave-type sintered YSZ sheet without significant defects was successfully obtained..

In this research, the polymers have been replaced by ceramics, which can endure a much harsher environment. The ceramic micro channels can be used in mechanical parts operated in extreme heat and in the presence of highly reactant chemicals.
In this work, the microchannels were fabricated by a combined process, which consists of micro powder imprinting and laser beam machining. A sheet composed of ceramic particles and polymers was prepared. A sacrificial layer, which was laser beam machined into the shape of the microchannels, was placed in between two ceramic compound sheets. A mould was placed on the upper surface then the imprinting process was carried out. By using a deep mould and replacing the sacrificial layer with a material that has larger elongation strength, the microchannels can be shaped into wavy channels which are along the imprinted wavy surface. After heating, the polymers decompose and the ceramic compact was sintered; ceramic micro channels with surface patterns are obtained.
As our microchannel forming process enables surface patterning and fabrication of out-of-plane micro channels, the surface area is increased, which enables applications as high efficiency heat exchangers. Moreover, by using yttria stabilized zirconia as structure material, which is used as electron exchanging membranes in solid oxide fuel cells, application on high efficiency fuel cells can be achieved.

On the other hand, Ti-6Al-4V alloy has normally poor workability. Therefore, Metal Injection Molding (MIM) process is hoped to be one of the technique to reduce the manufacturing cost. Recently many researches for Ti-6Al-4V compacts by MIM process were reported, however, there are a few reports about fatigue fracture properties. According to our previous study, they presented a problem of low fatigue strength compared to wrought material. In this study, to improve the fatigue strength of Ti-6Al-4V compacts by MIM process, a little amount of boron was added by using TiB2 powder. Boron showed the effect of refining the grain size of lamellar structure of Ti-6Al-4V compacts, which lead to increase the fatigue strength..

Thin sheets with a micro pattern have been expected to improve performance of solid oxide fuel cell (SOFC). The authors focused on imprinting and powder metallurgy processes, and have developed the combined process, which has been named micro powder imprinting (μPI) process. In this process, ceramic powder and polymer binder materials are mixed with pure water by milling machine. After drying out the water from the slurry, a thin compound sheet was obtained. Subsequently, the sheet was pressed using a fine patterned mold with heating to transcribe a micro pattern on the sheet. Finally, the imprinted sheet was heated for removing the polymer binder and for sintering. As further improvement of the process, a compound sheet was stacked on a pure polymer sheet during the imprint process to transcribe a micro pattern on the both sides of the sintered sample. The technique is useful for improved SOFC..

However, it has been still difficult to employ sintered material for high strength parts such as transmission gears of vehicle. Since many pores remain in the sintered body, resulted in lower fatigue strength. In this paper, rolling process is applied to sintered SCM415 gear to overcome this issue. Tooth surface on the sintered gear was densified by the rolling process. The surface area is the most critical parts of the gear, so that fatigue strength of the gear could be improved by the densification. As a result of the densification process, higher fatigue strength as same as that of wrought material was obtained..

MIM process is one of near net shape forming techniques of metal powders, which can produce complicated parts with low processing cost. The objective of this study is to investigate the effect of Cr contents on the magnetic properties of Fe-Cr compacts fabricated by MIM process. The magnetic properties were measured in DC and AC magnetic fields. Three types of MIM compacts were fabricated, which contain 5, 11 and 17 %Cr. These compacts were sintered at 1250-1350 °C for 3 hours in H2 and they showed nearly full density. As a result, magnetic flux density and coercivity of MIM compacts are comparable to that of Fe-13Cr-2Si material (K-M31) which is a conventional material. Moreover, Cr contents improve the initial permeability and relative loss factor in AC field..

Fujio TSUMORI, XU YANG, HYUNGOO KANG, Toshiko Osada, Hideshi Miura, SIMULATION OF DEFORMATION OF LAYERED SHEET DURING MICRO POWDER IMPRINTING PROCESS, XII International Conference on Computational Plasticity, 2013.09, This paper reports simulation of deformation during micro powder imprinting process, which is a newly developed process to form micro patterned surface on ceramic sheets. The process is proposed as a combined process of traditional hot-embossing and powder metallurgy. A compound sheet of powder material and polymer binder is pressed by a mold to be transcribed a micro-pattern on its surface. After pressing, the binder is removed by heating, and the sheet is sintered. Finally dense ceramic sheet with fine pattern can be obtained. This process can be used also for layered sheet of two different materials. By using this layered sheet, we can make a pattern not only on the surface of the upper layer but also along the interface between each layer. Of course, the same pattern with the mold’s shape can be transcribed on the surface, while, there can be found another micro pattern along the interface. These two patterns of the surface and the interface are useful to fabricate ceramic sheet with patterns on its both surfaces. For example, if a compound sheet was used as an upper layer and a pure organic sheet as a lower, the lower organic layer can act as a sacrificed layer. After debinding and sintering, only the upper layer remains, which has micro-patterns on the both sides.
The shape of interface between layers can be controlled by changing properties of layers. It could be also influenced by the imprinting conditions, such as temperature and pressure. In order to design the shape of the interface, finite element analysis was employed in the present paper. Mooney-Rivlin’s deformation model was used to express deformation of materials during imprinting. In this paper, we compared the simulated results with experimental data to show effectiveness of the present simulation method.

The mixed elemental materials, iron and wateratomized Ni powders, were utilized in this study. The microstructure of the compacts have been consistently structured heterogeneously by molding and sintering the mixed elemental powders as same as our previous reports. In this study, the microstructural aspects of the compact were changed by the characteristics of Ni powder, such as particle size, shape, and distribution, which play important roles in the deformation behavior. Eventually, tempered compacts added 6 mass% fine Ni powder showed ultrahigh strength of more than 2 GPa (290 ksi) and elongation of higher than 8 %. In order to understand how the microstructure results these high mechanical properties, we developed 2D finite element modeling based on the spatial distribution obtained experimentally. The simulated results of the models were compared to experimentally obtained behavior, and showed good agreements..

We employed an imprint process to give fine patterns onto a ceramic electrolyte sheet. The imprint process is a powerful tool to transcribe nano- to micro-patterns on materials. In the present work, a sheet of ceramic compound material was prepared, and micro patterns were given on the sheet. After debinding and sintering, dense ceramic sheet with fine patterns were obtained. We prepared three kinds of electrolyte sheets with different surface patterns using this technique. After applying anode and cathode layers, the three fuel cell samples were assembled to test the cell performance. It was resulted that the finer pattern caused the best performance in the three samples..

It was already reported that the present actuator can work even if the structure was miniaturized to nano-scale. In the present work, simple fabrication process with photolithography and PDMS casting was employed to obtain beam type structures with micro array of magnetic elements on their surface. Two samples with simple grid patterns were prepared for testing. These samples had the same grid pattern but different orientation, which caused directly opposite bending deformation under the same applied magnetic field. We used magneto finite element method (FEM) to explain the behavior of the present actuators..

The Inconel 718 and Rene 95 are representative Ni based superalloys. However, it is not easy to produce the complicated parts at low cost due to their poor workability. Moreover, segregation occurred in casting. Metal Injection Molding (MIM) process, one of near net shape forming of powders, has been applied to fabricate the both superalloy compacts. By optimizing MIM process parameters, near full density was obtained. Tensile strength of the heat-treated MIM compacts shows excellent values that are higher strength than that of wrought materials. Strength and fatigue properties at high temperature will be discussed in detail..

FLH is very important factor in direct metal laser forming (DMLF) process because amount of melted metal pool is decided by FLH and it affects to surface roughness, relative density and mechanical properties of DMLFed compacts. In this study, tensile specimens were manufactured in various FLH. And surface roughness, relative density and tensile strength were assessed. In the case of 100 m FLH, surface roughness was reduced and nearly full density (99.8 %) was obtained. Tensile strength of this dense compact was1080 MPa, which is higher than ASTM value..

Toshiko Osada, Munehiro Noda, Hyungoo Kang, Fujio Tsumori, Hideshi Miura, Dynamic Fracture Characteristics of Injection Molded Titanium Alloy Compacts, International Conference on Materials Processsing Tehcnology 2012, 2012.06, Titanium and its alloys are used in various fields because of their excellent characteristics; high specific strength, corrosion resistance, biocompatibility and so on. As the dynamic fatigue property is of great importance in practical use, fatigue characteristics of injection molded Ti and Ti-6Al-4V compacts were investigated in this study. Sintering conditions change relative density and pore structure of specimen, and this change causes variation of the fatigue strength. Since the sintered specimens contains pores inside, the fatigue strength of sintered specimen is generally lower than that of wrought materials. Fatigue strength obtained in this study was a third of static tensile strength, it is considered that crack start from a pore on the surface of the specimen during the test. The fracture behaviors of specimens are discussed in detail by in-situ observation of the crack propagation on the specimen surface. Furthermore, Cr powder was added to Ti-6Al-4V powder to improve the fatigue strength. Grain size in the sintered Cr-added specimen was much smaller than the specimen without Cr. Fatigue strength of Cr-added specimen was improved because of this micro structure. Moreover, HIP was conducted to Cr-added specimen. HIP specimen which has over 99 % relative density shows higher fatigue strength, and fracture behavior is similar to wrought materials..

Yang Xu, Fujio Tsumori, Hyungoo Kang, Toshiko Osada, Hideshi Miura, Improved Process for Fabrication of Solid Oxide Fuel Cell Based on the Micro Powder Imprinting Technology, International Conference on Materials Processsing Tehcnology 2012, 2012.06, Two improved fabricating processes are proposed to improve efficiency of a solid oxide fuel cell (SOFC) and to achieve the time saving in the process. The first process is based on the fabrication of high performance electrolyte sheet with micro patterns on the surface. A new manufacturing method of micro Powder Imprinting (μPI), which has the lower cost and fewer steps than conventional processes, is introduced to fabricate the thin YSZ sheet with the micrometer-scale patterns. Compound material of YSZ powder and organic binder is prepared to imprint micro patterns on the surface. Imprinted samples were debound and sintered, and then the well transcribed line and space patterns were obtained, the pitches of which were from millimeter scale to single micro scale. The second process is based on the thermal imprinting to an electrolyte-anode ceramic bilayer sheet. After imprinting, the co-sintering process was carried out. The resulting wavy interface between electrolyte and anode layer increased efficiency of SOFC and could avoid the peeling-off from each layer. The same technique would be applied for imprint process of triple-layer material, which is necessary to fabricate anode-electrolyte-cathode cell structure at one time..
