Profile
In the research group of Dr. Kazunari Sasaki, we focus on the R&D of fuel cell materials. Two major activities, on polymer electrolyte fuel cells (PEFC) and on solid oxide fuel cells (SOFC), are both supported by several research fundings, including national R&D project of SOFCs and PEFCs. In our reserach group, we have various facilities including 60 evaluation systems of fuel cell electrchemical performance/properties (with Solartron impedance analyzers, Potentiostat/Galvanostat, CVs, multimeters), microscopes (High-resolution FESEM-EDX-STEM, SEM-EDX, AFM, STM, KFM), materials evaluation apparatus (XRD, XPS, BET, TG-DTA, TG-MS etc.), several gas chromatographs and GC-MS, as well as preparation apparatus for electrode catalysts and fuel cells. Thus our graduate students and research staffs can prepare FC-related materials and fuel cells and can analyze their performanece by themselves. (1) Nano-structured Electrode Catalysts for PEFCs Polymer electrolyte fuel cells (PEFCs) are promising energy systems with several advantages including high energy density, low-temperature operation, short start-up time etc., so that automobile, portable, as well as stationary applications are of technological interest. However, in the state-of-the-art cells, a large amount of noble metals should be used, leading to too high cost of fuel cell systems. A higher performance of electrode catalysts using less amount of noble metals, especially platinum, is essential, and this is one of the most relevant technological tasks in PEFC research and development. In this research period, we focus on carbon support materials and oxide-based additives for electrode catalysts. Various types of carbon materials were applied and the influence of carbon nanostructure on electrochemical properties was analyzed to realize higher power generation characteristics and a reduction of noble metal loading of the electrode catalysts. Downsizing of electrode catalysts, Pt, was also carried out. We have succeeded, via colloidal processes, to prepare Pt nanoparticles with a crystallite size of ca. 3 nm. Effect of nanostructuring on electrochemical properties are also analyzed to establish materials design strategies of PEFC/DMFC electrode catalysts. (2) Multi-Fuel Capable SOFCs In our institution, we systematically characterize electrochemical performance, relevant transport properties of ceramic materials, the interactions between the fuel cell components and the fuel gas species, and equilibria in fuel gases. We wish to contribute to solid oxide fuel cells (SOFC) development and commercialization based on our fundamental research activities, e.g. by establishing optimum operational conditions of fuel cells, proposing alternative materials, and analyzing electrochemical reaction phenomena. We have focused on power generation characteristics of SOFCs operated with various kinds of fuel gases (including lower and higher hydrocarbons, alcohols, biogases, coal gases, GTL fuels, and fuels with various impurities), as one of the most advantageous features of SOFCs is their flexibility for fuel selections. Based on these advantages, we may realize e.g. zero-emission renewable energy systems with SOFCs. We have also developed sulfur-tolerant SOFCs with chemically modified fuel electrodes. Such research activities are conducted as the Director of International Research Center for Hydrogen Energy, the Director of Next-Generation Fuel Cell Research Center, and a Distingished Professor. Educational activities are made in Department of Hydrogen Energy Systems (Graduate School of Engineering), and Department of Mechanical and Aerospace Engineering (School of Engineering). In addition, based on various experiences with industry and public sectors, Prof. Sasaki is currently acting as a Senior Vice President, as well as various committee members in the central and local Governments.

    One of the most attractive features of solid oxide fuel cells is their flexibility for fuels so that internal reforming and/or simple external reforming may be possible. In this study, equilibria in various possible fuel gases are considered, and C-H-O diagrams are constructed. Power generation characteristics for these fuels are measured and compared with those for simulated reformed gas in equilibrium compositions. We have succeeded to demonstrate direct-alcohol SOFCs for e.g. methanol, ethanol, and propanol. Mixtures of CH4 and CO2 are used as simulated biogas, and iso-octane (C8H18) and n-dodecane (C12H26) are highlighted as simulated gasoline and kerosene, respectively. Influence of fuel impurities on power generation characteristics is also discussed.

    Nanostructured Platinum-based electrode catalysts were prepared via in-situ colloidal impregnation for polymer electrolyte fuel cells. Crystallite size, grain size, and distribution of Pt nanoparticles on carbon support materials were characterized by XRD, TEM, high-resolution FESEM, and STEM. Effective surface area and kinetically-controlled current density of Pt electrode catalysts were analyzed by cyclic and hydrodynamic voltammetry using rotating disk electrodes. PEFCs with these electrode catalysts were also prepared and their I-V characteristics were examined at 80oC.

    We have succeeded to develop Pt electrode catalysts with a diameter of a few nm, supported on carbon nanofibers with different structures (including herringbone-type fibers, platelet-type fibers, and highly-conductive vapor-grown fibers), carbon nanotubes, as well as carbon black. The dependencies of nanostructure and electrochemical properties on crystallographic structure of carbon support materials and preparation conditions of electrode catalysts are analyzed and discussed. Nanostructural design of PEFC electrode catalyst layers using carbon nanofibers as catalyst supports and electrode fillers is also discussed.

    Power generation characteristics of solid oxide fuel cells (SOFCs) for alcohol-based fuels are measured and compared with those for simulated reformed gas in equilibrium compositions. We demonstrate direct-alcohol SOFCs for methanol, ethanol, propanol, and butanol. Current-voltage characteristics for the methanol-based fuel are comparable to those for the simulated reformed gas at 1000degreesC because of fast kinetics for thermal decomposition of methanol with H2O. With increasing carbon number of alcohols and/or with decreasing operational temperature of SOFCs, a decrease in cell voltage is observed associated with slower decomposition and/or reforming kinetics of alcohols.

    Because chemical compositions in thermodynamic equilibrium for various fuel gases are specified by the ratios among carbon, hydrogen, and oxygen, carbon-hydrogen-oxygen (C-H-O) ternary diagrams are useful to present relevant operational conditions of fuel cells. Such C-H-O ternary diagrams are constructed, describing the carbon deposition region, the fuel gas region, partial pressures of gaseous species including O-2, H-2, and CO, and electromotive force corresponding to the theoretical open circuit voltage of fuel cells. Such ternary diagrams present these operational conditions for any given C-H-O ratios without any additional calculations.

    Using thermochemical data of ca. 300 compounds consisting of carbon, hydrogen, and oxygen, the amounts of equilibrium products have been calculated for various fuel cell fuels including alkanes (CH4, C3H8, C8H18, C12H26), alcohols (CH3OH, C2H5OH, C3H7OH), alkenes, alicyclic hydrocarbons, and dimethyl ether, as well as for other hydrocarbon-containing fuels such as biogas and coke oven gas, in the temperature range between 100 and 1000degreesC. It has been revealed that the major constituents in typical fuel cell gases in thermodynamic equilibrium are H-2(g), H2O(g), CO(g), CO2(g), CH4(g), and C(s). Possible minor constituents are specified while their concentrations were negligibly low. Derived are the minimum amounts of H2O and CO2 for reforming and O-2 for partial oxidation, thermodynamically essential to prevent carbon deposition.

    The low-temperature defect chemistry of oxides is considered, characterized by frozen-in interaction with the ambient oxygen and reversibility of internal interactions, in particular the redistribution of electronic carriers. Analytical relations describing ionic and electronic defect concentrations are derived for various conditions. The presence of redox-active, i.e., deep-level, dopants proves to be of special interest in this context. The analytical relations permit the detailed discussion of the dependencies of the charge carrier concentrations on the control parameters. Such analytical relations are useful for understanding and tailoring defect concentrations and thus related properties of electroceramics.

    Using oxides as examples, the defect chemistry is systematically analyzed for a low-temperature regime, at which the oxygen exchange equilibrium reaction is no longer reversible, while the internal defect equilibrium reactions (in particular, the electronic transfer processes) may still be reversible. For the partially frozen-in states as well as for the complete equilibrium cases, defect concentrations are numerically calculated for idealized model oxides including pure, acceptor-doped, and donor-doped oxides. Foreign ions (major/minor, shallow/deep, acceptor/donor), oxygen vacancies, and oxygen interstitials are taken into account as redox-active defects. The deep-level (redox-active) defects often dominate defect concentrations in the partially frozen-in states, while the major dopants fix the concentrations in complete equilibrium. The temperature and oxygen partial pressure dependencies of defect concentrations in the partially frozen-in states are discussed. The description does not only allow one to extend the defect chemistry to lower temperatures, such as room temperature, but also offers a quantitative basis for manipulation and prediction of defect concentrations in ionic crystals. Thereby, the physical and chemical performance of such materials may be controlled at temperatures lower than those at which the oxygen nonstoichiometry is established. The results are equally relevant for applications in solid state physics (e.g., compound semiconductors) and in solid state chemistry (e.g., solid electrolytes, mixed conductors).

    Language:English   Publishing type:Research paper (scientific journal)  

    Phase equilibria in the system ZrO2─InO1.5 have been investigated in the temperature range from 800° to 1700°C Up to 4 mol%, InO1.5 is soluble in t‐ZrO2 at 1500°C. The martensitic transformation temperature m→t of ZrO2 containing InO1.5 is compared with that of ZrO2 solid solutions with various other trivalent ions with different ionic radii. The diffusionless c→t′ A phase transformation is discussed. Extended solid solubility from 12.4 ± 0.8 to 56.5 ± 3 mol% InO1.5 is found at 1700°C in the cubic ZrO2 phase. The eutectoid composition and temperature for the decomposition of c‐ZrO2 solid solution into t‐ZrO2+InO1.5 solid solutions were determined. A maximum of about 1 mol% ZrO2 is soluble in bcc InO1.5 phase. Metastable supersaturation of ZrO2 in bcc InO 1.5 and conditions for phase separation are discussed.

    Language:English   Publishing type:Research paper (scientific journal)  

    Solid oxide fuel cells (SOFCs) with proton-conducting solid electrolyte, instead of the oxide-ion conducting solid electrolyte have attracted attentions because of their high potential to reduce operating temperatures and to enhance the electrical efficiencies of SOFCs. In addition, the proton-conducting SOFCs with multistage electrochemical oxidation configuration will be promising technology for critically-high electric efficiencies. However, it is known that there are non-negligible charge -carriers other than protons in typical proton-conducting solid oxide electrolytes at relatively high temperatures. The existence of the partial conductivities of holes and/or electrons will cause the internal leakage current that consumes fuel but never generates any electrical power output. The higher ratio of the leakage current to external current will more deteriorate the electrical efficiency. In this study, the effects of blocking -layers formed on the air side surface of base electrolyte layer consisting of BaZr0.8Y0.2O3-δ (BZY82) for suppressing the leakage current have been investigated by using electrochemical parameters of the partial conduction of the materials. The chemical potential profile and leakage current showed large dependence on the material of the blocking-layer. Lanthanum tungstate was found to play a role as unique and strong blocking-layer against the leakage current.

    The oxygen deficiency or excess, as reflected in the nonstoichiometry of oxide films, plays a crucial role in their functional properties for applications such as micro solid oxide fuel cells, catalysis, sensors, ferroelectrics, and memristors. High concentrations of oxygen vacancies may be beneficial or detrimental according to the application, and hence there is interest in controlling the oxygen content of films without resorting to compositional changes. Here, we demonstrate that substantial changes in the nonstoichiometry of Pr0.1Ce0.9O2-δ (PCO), a model mixed ionic electronic conductor, can be achieved by fabricating multilayers with an inert material, SrTiO3 (STO). We fabricated heterostructures using pulsed laser deposition, keeping the total thickness of PCO and STO constant while varying the number of layers and thickness of each individual layer, to probe the effects of the PCO/STO interfaces. Conductivity measurements as a function of oxygen partial pressure (PO2 ) and temperature showed a significant weakening of the PO2 dependence compared to bulk PCO, which scaled with the density of interfaces. We confirmed that this change was due to variations in nonstoichiometry, by optical transmission measurements, and show that the lower oxygen content is consistent with a decrease in the effective oxygen reduction enthalpy of PCO. These results exemplify the dramatic differences in properties between films and their bulk counterparts, achievable by interface engineering, and provide generalized insight into tailoring the properties of mixed ionic electronic conductors at the nanoscale.

    Surface oxide layer of Fe-Cr-Al alloy was investigated to apply for metal support material of SOFCs. We already found that electrical resistance of the surface oxide layer can be decreased by La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) coating and heat-treatment. The morphology of the surface oxide layer changed to a columnar structure consisting of γ-Al2O3 polycrystal and Sr3Al2O6 growing outward in the same direction. In this study, we investigated heat-treatment condition to increase durability of the oxide layer. The Fe-Cr-Al alloy was firstly coated with LSCF and pre-heat treated in a vacuum at 1000oC for 1 h. Stability of mass gain and electrical resistance in air at 700oC was significantly improved. The morphology of the surface oxide layer was a complex structure consisting of α-Al2O3/Sr3Al2O6.

    Perovskite La0.9Sr0.1Ga0.9Mg0.1O3-δ (LSGM) is one of the fastest known oxide ion conductors, with reported enhanced p-type electronic transference numbers at grain boundaries, attributed to space charge effects. As this material is applied as a solid oxide fuel/electrolysis cell electrolyte, it is of interest to learn how its mixed conductivity may be tailored. Field assisted sintering technique/spark plasma sintering (FAST/SPS) and conventional sintering without field or pressure were employed to prepare pellets with various grain sizes, in order to systematically assess the influence of processing route on the mixed conductivity. AC-impedance spectroscopy and the brick layer model were applied to determine local conductivities as a function of temperature, oxygen partial pressure, and dc bias. With increasing sintering temperature and grain size, the following trends were observed: larger electrical grain boundary (GB) widths, higher GB potentials, lower specific GB conductivity, greater dc-bias dependence of GB conductivity, higher pO2-dependence of GB conductivity indicating higher electronic transference numbers, and lower pre-exponential factor for specific GB conductivity. These results suggest an increasing GB space charge effect with increasing sintering temperature/grain size, which coincided with increasing compositional uniformity by TEM and EDS. The results confirm that sintering route is an important variable for tailoring mixed conduction.

    Language:English   Publishing type:Research paper (scientific journal)  

    We investigated the treatment of Fe-Cr-Al alloy for application in solid oxide fuel cells (SOFCs). The electrical resistance of the Al2O3-based surface oxide layer on the alloy decreased and was stable when La0.6Sr0.4Co0.2Fe0.8O3(LSCF), La0.8Sr0.2MnO3(LSM), LaNi0.6Fe0.4O3(LNF), or Pr0.8Sr0.2MnO3(PrSM) were first coated on the alloy and heat treated at 700 °C in air. The activation energy, calculated from the resistance, also suggested that the surface oxide became more conductive with treatment. The surface oxide layer after treatment had a microstructure of columns growing outward in the same direction, containing small amounts of elements such as Sr, Ni, Fe, La, Mn, and Pr. The microstructure consists of polycrystalline γ-Al2O3and small amounts of Al compounds with these elements. In the case of the LNF coating, the formation of NiAl2O4was observed.The enhanced electrical conductivity may have resulted from the arrangement of the columnar structure, along with the electronic conduction path generated by the reaction of γ-Al2O3with these elements.

    Rapid oxygen transport across the gas/solid interface (oxygen exchange) is critical for solid oxide fuel cell electrode performance. In this work, La and Sm are shown to dramatically improve the oxygen exchange rate on Pr0.1Ce0.9O2-δ thin films (>50 x at 450 °C) as compared to a freshly deposited film without La or Sm oxide. A surface cleaning effect from the La and Sm is suspected as the source of the enhancement, though catalytic activity from La and Sm may also play a role.

    Eu-doped cerium oxide was synthesized and its crystal structure was analyzed by X-ray diffraction. The electrical conductivity was measured by impedance spectroscopy at 350-900 °C over a wide range of controlled oxygen partial pressures, from H2 to O2, using gas mixtures. In the high pO2 region, ionic conductivity is predominant, and the activation energy for total conductivity is 0.8 ± 0.01 eV. In low pO 2, the conductivity is found to obey a - 1/4 power law dependence on pO2, with an enthalpy of reduction of 4.2 ± 0.16 eV. These results demonstrate that Eu has a similar effect on electrical properties as Gd or Sm acceptor dopants in ceria, namely, that Eu shows no evidence for multivalent behavior; rather, it appears to be a fixed valent dopant in the fluorite structured ceria, in contrast to prior studies finding multivalency of Eu in perovskite oxides under similar conditions.

    Language:English   Publishing type:Research paper (scientific journal)  

    Donor doping of the p-type solid oxide fuel cell cathode, Sr(Ti,Fe)O 3-δ, with La was pursued to examine the role of minority charge carriers (electrons) on the oxygen exchange rate. Model dense thin film cathodes of (La,Sr)(Ti,Fe)O3-δ were fabricated by pulsed laser deposition. Optical transmission spectroscopy measurements demonstrated that the addition of the donor La resulted in a change in valence state of Fe from 4+ to 3+, suggesting a rise in Fermi level. The activation energy of the cathode's area specific resistance, studied by impedance spectroscopy, was found to be lower with La addition; however, the magnitude of the area specific resistance was not lowered.

    Impurities on the surface of SOFC electrodes can dramatically reduce their interfacial transport. In this work, we use a novel in situ optical absorption relaxation technique to derive the oxygen exchange rate in the absence of electrodes, thereby studying the "innate" material. Si is found to be an impurity in high concentration, with its presence associated with an orders of magnitude decrease in oxygen exchange rate. Addition of La to the electrode surface is found to substantially improve oxygen exchange rate.

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    A study of the influence of annealing in atmospheres with defined oxygen partial pressures (1.5×10-6 Pa≤PO(2)≤10+5 Pa) on the electrical resistivity ρ(T), magnetic susceptibility χ(T), and heat capacity cp(T) of ceramic samples of Nd0.67Sr0.33MnO3-δ is presented. ρ(T) at 1000 °C shows no appreciable change for 10+2 Pa≤PO(2)≤10+5 Pa. For samples annealed in air a sharp peak is found in cp(T) and in ρ(T) at the ferromagnetic transition (TC≈238 K). The insulator-metal transition is observed below TC as a broad peak in ρ(T). Annealing at lower PO(2) leads to an increase of ρ whereas TC decreases only by ≈2 K. Annealing at PO(2)≤6.3×10-2 Pa suppresses TC and results in spin canting and a vanishing of the peak in cp(T). The specific heat (2-300 K) for samples annealed in air and in Ar/5% H2 is determined and thermodynamic standard values are calculated. The problem of the separation of cp(T) into lattice, electronic, and Mn and Nd magnetic contributions is discussed. cp(T<20 K) is dominated by a Schottky-like anomaly from the Zeeman-split ground-state doublet of Nd3+. A large quasi-linear term is mimicked by a broadening of the Schottky-like anomaly and by magnetic contributions from Mn in oxygen-deficient samples. The results are discussed in the context of oxygen deficiency δ, carrier concentration, defect chemistry, and disorder.

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    The dynamic behavior of the oxygen ion conductivity of a cubic Zr0·85Ca0·15O1·85 single crystal has been investigated with AC impedance spectroscopy and a dynamic pulse method as a function of both temperature and frequency between 450 and 1200 K and 20 and 108 Hz. This is the frequency-temperature range where the relaxation dispersion of the ionic conductivity can be observed. From the temperature dependence of the relaxation frequency, the diffusion coefficient and the mobility of oxygen vacancies were determined. In the entire temperature range investigated, the temperature dependence of the ionic conductivity of a Zr0·85Ca0·15O1·85 single crystal arises exclusively from the temperature dependence of the mobility of oxygen vacancies, the concentration of which remains constant with temperature and is equal to the concentration of all extrinsic oxygen vacancies created by calcia stabilizing. No transition in the Arrhenius plot of the ionic conductivity due to a gradual dissociation of oxygen vacancy-defect cation associates, as proposed in the literature, has been observed. A simple model for the temperature dependence of the ionic conductivity of solid electrolytes in terms of the parallel and serial combination of RC-elements is given.
