PROBLEM TO BE SOLVED: To provide a fuel cell with the output voltage and current density enhanced by forming a composite polymer film structured thin, having a high strength and causing less cross-leak amount of the fuel gas and using this composite polymer film as a solid polymer electrolyte film for the fuel cell. SOLUTION: A porous resin base film is impregnated with the solid polymer electrolyte which is allowed to deposit, and part of the electrolyte is formed as a skin layer 3 on at least one surface of the porous resin base film 2. |
