PROBLEM TO BE SOLVED: To provide a fuel cell in which local stress concentration between a fuel cell body and a collector is reduced.SOLUTION: The fuel cell includes: a flat plate-like fuel cell body formed by laminating an air electrode layer, an electrolyte layer, and a fuel electrode layer, wherein a surface of one of the air electrode layer and the fuel electrode layer is a first main surface; and a flat plate-like collector which is in contact with the first main surface of the fuel cell body and is laminated in the laminating direction. That region of the collector which corresponds to the first main surface has a rectangular boundary having chamfered corners. |
