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 C_(3-10)alkyl group as a side chain thereof. The release layer may have a glass transition temperature of about 210 to 350C. The release layer may have a transition point of a dynamic storage modulus E in a range from -50 to 100C. 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.
