Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid polymer electrolyte fuel cell which, although being low in internal resistance, has sufficient generating performance, without adversely affecting electrode reactions, by having a high water content, and using a water-repellent polymer electrolyte film for its surface. SOLUTION: This fuel cell comprises a solid polymer electrolyte film having ion exchangeability and a positive electrode and a negative electrode which are placed in contact with both sides thereof. In this case, the surface of the solid polymer electrolyte film has a water-repellent solid polymer electrolyte film formed by the crosslinked structure of styrene and divinyl benzene, the water repellency angle of the surface of the solid polymer electrolyte film being 85 deg. or more.
