<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell wherein a stable output is kept by reducing the contact resistance between a current collector and a cell separator on an air electrode side. <P>SOLUTION: This fuel cell 10 has the structure in which a plurality of unit cells are laminated through metallic cell separators 211 and 212 (a heat resisting alloy such as SUS430). Each cell unit comprises a solid electrolyte layer 11 (a stabilized zirconia such as ScSZ, etc.), a fuel electrode 12 (Ni and ScSZ, etc.) provided on one side of the solid electrolyte layer, the air electrode 13 (La<SB>1-x</SB>Sr<SB>x</SB>MnO<SB>3</SB>, etc.) provided on the other side, and the current collector 5 (a dense body consisting of inconel or the like) interposed between the air electrode and the cell separator. At least a part of the current collector 5 is the dense part, and at least a part of the dense part is in contact with the cell separator through a bonding material (silver brazing filler material, etc.). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
