PURPOSE:To restrain the mismatch of the thermal expansion coefficients of a fuel electrode side collecting body and an electrolyte (YSZ) within 10%, and also reduce weight of a fuel electrode side collecting plate, with required electronic conductivity ensured. CONSTITUTION:A fuel electrode collecting plate is composed of porous Ni/AB2O4 thermet (A=Mg, Mn, Fe, Co, Ni, Cu, Cd, and Zn, B=Al, Fe, and Cr). Consequently, since AB2O4 has a low thermal expansion coefficient, a thermal expansion coefficient can be restrained within an allowable range with electronic conductivity required for as a collecting plate ensured, and the logical density of a fuel electrode side collecting plate can be reduced. Catalyst activity, high for a long time, can be obtained for reforming reaction of hydrocarbon fuel (C/H fuel) such as methane, and methanol. |
