摘要： A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer containing an olefin unit having a C3-10alkyl group as a side chain thereof and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.

摘要： A release layer of a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell comprises a cyclic olefin polymer comprising an olefin unit having a C3-10alkyl group as a side chain thereof. The release layer may have a glass transition temperature of about 210 to 350° C. The release layer may have a transition point of a dynamic storage modulus E′ in a range from −50 to 100° C. An ion exchange layer comprising an ion exchange polymer may be laminated on the release layer of the release film by a roll-to-roll processing to produce a laminate. The release film may be separated from the laminate to give the membrane electrode assembly. The release film achieves improved production of a membrane electrode assembly (an electrolyte membrane and/or an electrode membrane) of a polymer electrolyte fuel cell.
