Beschreibung
Zusammenfassung:	Disclosed is a fuel cell (10) in which an electrolyte membrane-electrode structure (12) is held between a first separator (14) and a second separator (16). The electrolyte membrane-electrode structure (12) comprises a solid polymer electrolyte membrane (26), a cathode-side electrode (28) and an anode-side electrode (30). An end portion of the solid polymer electrolyte membrane (26) projects outwardly beyond end portions of gas diffusion layers (30a, 28a), and the both surfaces of the end portion of the solid polymer electrolyte membrane (26) are held between a first protective film (32) and a second protective film (33). The thickness of the first protective film (32) is set to be thinner than the thickness of the second protective film (33).
