摘要：
A membrane/electrode assembly for solid polymer fuel cells is disclosed wherein a fluorinated sulfonic acid polymer having a monomer unit represented by the following general formula (3): (3) (wherein, Rf1 represents a divalent perfluorohydrocarbon group having 4-10 carbon atoms) is used for at least one of the membrane and the catalyst binder. The fluorinated sulfonic acid polymer has a melt flow rate (MFR) of not more than 100 g/10min at 270˚C when the -SO3H group in the polymer is changed into -SO2F.
