摘要： The present invention intends to provide a solid oxide fuel cell having a supported electrolyte film, which shows sufficiently high reliability, yields a high output, and exhibits high output power density per unit volume. The present invention is characterized by use of a first cermet comprising catalyst and a second solid electrolyte, which has a bending strength of more than 500 MPa and exhibits oxide ion conductivity, for a fuel electrode substrate in an SOFC having a supported electrolyte film equipped with an electrolyte-electrode assembly that is made by bonding the fuel electrode substrate and an air electrode on both sides of an electrolyte film consisting of the first solid electrolyte capable of exhibiting oxide ion conductivity. As a preferred embodiment, stabilized zirconia containing 2 to 4 mol% yttria or 3 to 6 mol% scandia is preferred for the second solid electrolyte.

摘要： A material for a fuel electrode of a solid oxide fuel cell with which volume change of the fuel electrode during performance of oxidation-reduction cycles is reduced as compared to conventional materials. The fuel electrode material includes a powder containing: (a) at least one of nickel and nickel oxide, (b) at least one of titanium oxide (IV) and a titanium source capable of changing into titanium oxide (IV) by heat treatment in air, (c) a solid electrolyte exhibiting oxide ion-conductivity. The fuel electrode material is sintered to prepare the fuel electrode, which is provided for the solid oxide fuel cell. The resulting fuel cell shows a stable power generation even after exposure of the fuel electrode to oxidation-reduction cycles.
