Title:
RELEASE FILM FOR MOLDING SOLID POLYMER FUEL CELL MEMBERS
Document Type and Number:
WIPO Patent Application WO/2017/026365
Kind Code:
A1
Abstract:
[Problem] To obtain a release film for molding solid polymer fuel cell members, which has fine transferability (releasability), in which the rate of thermal shrinkage is suppressed, and which enables molding without causing cracking or the like to be formed in a polymer electrolyte film or a catalyst layer even when thermal molding at a high temperature equal to or higher than 150°C is performed. [Solution] A release film for molding solid polymer fuel cell members, which is obtained by laminating a release layer on at least one side of a polyester film, and is characterized in that the rate of thermal shrinkage after a heat treatment is performed at 160°C for 30 minutes is not higher than 0.8%.
