Abstract
A membrane-electrode assembly for solid polymer electrolyte fuel cell that exhibits superior dimensional stability to high temperature of hot water generated on power generation, and that has both excellent power generation performance and durability in a low temperature environment is provided. According to the membrane-electrode assembly for solid polymer electrolyte fuel cell in which a polyarylene-based copolymer having a specific repeating constitutional unit is used as a proton conductive membrane, the membrane-electrode assembly for solid polymer electrolyte fuel cell that exhibits superior dimensional stability to high temperature of hot water generated on power generation, and that has both excellent power generation performance and durability in a low temperature environment can be provided.
