Abstract:
1. A membrane for polymer electrolyte fuel cell used for preparing a membrane-electrode assembly, which comprises: a hydrocarbon anion-exchange resin membrane wherein an anion-exchange group is covalently bonded to a hydrocarbon resin, and an adhesive layer used for bonding a catalyst electrode layer formed on at least one side of the hydrocarbon anion-exchange resin membrane, wherein the adhesive layer consist essentially of a hydrocarbon anion-exchange resin, which hydrocarbon anion-exchange resin is made of a styrene-based anion-exchange resin in which a quaternary ammonium salt group is covalently bonded to a non-crosslinked styrene-based elastomer, and has a Young's modulus of 1 to 1,000 MPa, and wherein the adhesive layer has a solubility of less than 1% by mass in water of 20° C. and has a thickness of 1 to 10 μm.
