FUEL CELL AND METHOD FOR MANUFACTURING FUEL CELL

A fuel cell includes a membrane electrode assembly, a first gas diffusion layer, a second gas diffusion layer, a support, and a cover sheet. There is a space having a distance Lbetween an end face of the support and an end face of the membrane electrode assembly. The expression of E>0.048×L/tis satisfied, where E is the elastic modulus of the cover sheet, and t is the thickness of the cover sheet. The reduction rate of voids in at least a part of a portion of the first gas diffusion layer under which the cover sheet is located with respect to voids in a portion of the first gas diffusion layer under which the cover sheet is not located is 5% or more and 25% or less.
