PROBLEM TO BE SOLVED: To improve power generating efficiency by determining the thickness of an oxidizing agent electrode current collector to be optimum. SOLUTION: In a solid electrolyte fuel cell wherein a fuel electrode layer 3 and an air electrode layer 4 are arranged on both faces of a solid electrolyte layer 2, the fuel electrode current collector 6 and an air electrode current detector 7 made of a porous cushion material are arranged on the outsides of these layers, and a separator 8 is arranged on the outsides of these layers, the thickness T of the air electrode current collector 7 is set to be 0.5 mm or more, preferably 0.8 mm or more. |
