PROBLEM TO BE SOLVED: To restrict the thermal stress distribution in a plane of a power generation film from being unbalanced. SOLUTION: In a flat plate shaped solid electrolytic fuel cell provided with an inter-connectors 11 and 12 spaced with each other and arranged in parallel and a protruded and recessed power generation film 13 having an air pole arranged between these inter-connectors and formed respectively at a solid electrolyte and on both face sides thereof and a fuel pole and constituted so as to flow an oxidizer 14 on an air pole side of the power generation film 13 and flow a fuel on the foregoing fuel pole side, recessed and protruded pitches of the power generation film 13 become coarse from an inlet from the oxidizer 14 or the fuel toward an exit direction. |
