摘要： A method for producing an electrode-membrane-frame assembly according to the present invention includes arranging a previously molded first molded body on a circumferential region of first catalyst layer close to first gas diffusion layer, arranging a previously molded second molded body on a circumferential region of second catalyst layer close to second gas diffusion layer, and forming a third molded body by injection molding so as to integrally connect the first molded body and the second molded body and not to be directly in contact with an inner side region of second main surface of a polymer electrolyte membrane positioned on an inner side of an outer edge part of the second molded body when viewed from a thickness direction of the polymer electrolyte membrane, whereby a frame having the first, second, and the third molded body is formed. Thus, the polymer electrolyte membrane can be prevented from deteriorating.
