PURPOSE: To provide a fuel electrode for a barium-cerium oxide solid electrolyte fuel cell having small polariztion and high performance by optimizing a particle diameter, mixing ratio or the like of raw material powder. CONSTITUTION: This fuel electrode for a barium-cerium oxide solid electrolyte fuel cell is composed of a sintered body of fuel electrode raw material having a particle diameter of 0.1-2μm. As the fuel electrode raw material, a mixture of at least one kind of powder selected from a group composed of Ni, NiO and Co with barium-cerium oxide powder is used, and after sintering in the atmosphere, a reducing process is applied in the hydrogen atmosphere to obtain a porous sintered body electrode. The mixing ratio of the barium-cerium oxide powder is desirable within a range of 5-30wt.%. |
