Title:
SOLID POLYMER ELECTROLYTIC FILM, SOLID POLYMER FUEL CELL EMPLOYING IT, AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/051776
Kind Code:
A1
Abstract:
A solid polymer electrolytic film in which bondability to a catalyst layer is enhanced even if an ion-exchange resin in the catalyst layer is composed of a different material. In a fuel cell (10), the solid polymer electrolytic film (20) consists of a first solid polymer electrolytic film (200) and second solid polymer electrolytic films (202, 204) provided on the opposite sides thereof. The second solid polymer electrolytic films (202, 204) are composed of the same material as an ion-exchange resin (not shown) contained in the catalyst layer (30).
