PROBLEM TO BE SOLVED: To provide a fuel cell capable of especially shortening a dimension of a power generation cell in the lamination direction as much as possible and capable of also achieving compactification.SOLUTION: A fuel cell 10 includes a power generation unit 12 in which a first metal separator 14, a first electrolyte membrane/electrode structure 16a, a second metal separator 18, a second electrolyte membrane/electrode structure 16b and a third metal separator 20 are provided. A second fuel gas inlet buffer part region 36b which is a deep groove buffer part of the second metal separator 18 and an inlet deep embossed part region 84a which is a fuel gas recess of a first resin frame member 70 are overlapped on each other to form a comparatively large buffer part space in the lamination direction. |
