Beschreibung
Zusammenfassung:	The present invention discloses a membrane for polymer electrolyte fuel cell, which comprises a hydrocarbon cation exchange resin membrane wherein a cation exchange group is covalently bonded to a hydrocarbon resin, and an adhesive layer formed on at least one side of the hydrocarbon cation exchange resin membrane, wherein the adhesive layer is made of a hydrocarbon cation exchange resin having a Young's modulus of 1 to 300 MPa and a solubility of less than 1% by mass in water of 20°C; and a membrane-electrode assembly which is obtained by forming a catalyst electrode layer on at least one side of the above-mentioned membrane for polymer electrolyte fuel cell.
