A curable resin composition for fuel cell electrolyte films characterized by comprising (1) 100 parts by mass of a monomer having at least one ethylenically unsaturated group per molecule and having, per molecule, either at least one, ionically conductive group or at least one precursor group capable of giving an ionically conductive group through a chemical reaction, (2) 10-400 parts by mass of an oligomer which has, per molecule, at least two reactive groups copolymerizable with the ethylenically unsaturated group of the ingredient (1) and has a number-average molecular weight of 400 or higher, (3) 10-400 parts by mass of a fluororesin, and (4) 0-2,000 parts by mass of a solvent.

L~invention concerne une composition de résine durcissable pour films électrolytiques de pile à combustible, caractérisée en ce qu~elle comprend (1) 100 parties en masse d~un monomère ayant au moins un groupe éthyléniquement insaturé par molécule et ayant, par molécule, soit au moins un groupe ioniquement conducteur soit au moins un groupe précurseur capable de produire un groupe ioniquement conducteur par le biais d~une réaction chimique, (2) 10 à 400 parties en masse d~un oligomère ayant, par molécule, au moins deux groupes réactifs pouvant être copolymérisés avec le groupe éthyléniquement insaturé de l~ingrédient (1) et ayant un poids moléculaire moyen en nombre de 400 ou plus, (3) 10 à 400 parties en masse d~une fluororésine et (4) 0 à 2 000 parties en masse d~un solvant.
