摘要：
A membrane electrode assembly for a polymer electrolyte fuel cell characterized by using, as solid polyelecrolyte of at least one of a membrane and a catalyst binder, a fluorinated sulfonic acid polymer with a monomer unit represented by the following general formula (3): (wherein Rf1 is a bivalent perfluoro-hydrocarbon group having a carbon number of from 4 to 10), wherein said fluorinated sulfonic acid polymer has melt flow rate (MFR) not higher than 100 g/10 min at 270° C. when a —SO3H group in said polymer is converted to —SO2F.
