RESIN FILM, LAMINATE, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING FUEL CELL

摘要

This resin film is formed by a resin composition including: a cyclic-olefin-based resin (A) including an olefin unit that includes a C3-10 alkyl group in a side chain thereof; and a chlorine-containing resin (B). The chlorine-containing resin (B) may be a vinylidene-chloride-based polymer. The proportion of the chlorine-containing resin (B) to 100 parts by weight of the cyclic-olefin-based resin (A) may be from 0.5 to 60 parts by weight. Because this film has appropriate releasability and adhesiveness with respect to an electrolyte membrane and an electrode membrane of a solid polymer fuel cell, and can adhere tightly to a general-purpose substrate film without interposing an adhesive layer such as a highly adhesive layer, this film is suitable as a release film for producing a membrane electrode assembly of a solid polymer fuel cell.
