Summary: | PROBLEM TO BE SOLVED: To provide a membrane-electrode structure for a solid polymer fuel cell equipped with a solid polymer electrolyte film containing a sulfonated polymer having excellent hot water resistance and mechanical characteristics even with an increased amount of introduction of a sulfonic acid group. SOLUTION: In the membrane-electrode structure for a solid polymer fuel cell equipped with an anode electrode on one face of the solid polymer electrolyte film and a cathode electrode on the other, the solid polymer electrolyte film contains a polyarylene group copolymer having a constitutional unit expressed in general formula (1'). In the formula, Y denotes either -CO- or -SO2-, Z denotes either oxygen atom, sulfur atom, -CO-, -SO2-, or -SO-, l denotes an integer of 0 to 4, and m denotes an integer of 0 or larger. Ar denotes a structure expressed in general formula (2') or (3'). COPYRIGHT: (C)2007,JPO&INPIT |
