PROBLEM TO BE SOLVED: To prevent excessive load on an outer peripheral end of an electrode catalyst layer when a fuel cell is fastened, and to reliably prevent damage to a solid polymer electrolyte membrane.SOLUTION: An electrolyte membrane/electrode structure 12 with protective films includes: an MEA 12a that has a cathode electrode 20, and an anode electrode 22, that sandwich a solid polymer electrolyte membrane 18 therebetween; and protective films 24a and 24b that are bonded to an outer peripheral end edge part of the solid polymer electrolyte membrane 18. The electrolyte membrane/electrode structure 12 with protective films has a power generation section 46 and an edge periphery section 48. On an outer peripheral edge thereof having contact with the MEA 12a, a cathode separator 14 has a depression 14c that houses the edge periphery section 48 including an outer peripheral end 20ae. On an outer peripheral edge thereof having contact with the MEA 12a, an anode separator 16 has a depression 16c that houses the edge periphery section 48 including an outer peripheral end 22ae. |
