Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a membrane-electrode assembly for a fuel cell with improved durability by restraining permeation of fuel and an oxidant between an anode and a cathode. SOLUTION: The membrane-electrode assembly for the fuel cell 10 is formed by laminating the anode; a polymer electrolyte membrane 2 having proton conductivity; an inside electrode 3 having electron conductivity; an electron conductive polymer electrolyte membrane 4 having proton conductivity and electron conductivity; and the cathode 5; in a thickness direction of the polymer electrolyte membrane 2 in this sequence. A thickness of the polymer electrolyte membrane 2 is thinner than that of the electron conductive polymer electrolyte membrane 4. The fuel cell utilizing the membrane-electrode assembly for fuel cell use 10 is provided. COPYRIGHT: (C)2007,JPO&INPIT
