Abstract
Disclosed is a fuel cell in which an electrolyte membrane-electrode structure is held between the first separator and a second separator. The electrolyte membrane-electrode structure comprises a solid polymer electrolyte membrane, a cathode-side electrode and an anode-side electrode. An end portion of the solid polymer electrolyte membrane projects outwardly beyond end portions of gas diffusion layers, and the both surfaces of the end portion of the solid polymer electrolyte membrane are held between the first protective film and a second protective film. The thickness of the first protective film is set to be thinner than the thickness of the second protective film.
