PROTON CONDUCTIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a proton conductive resin composition which has in the presence of water a good proton conductivity and is capable of forming a film showing flexibility and a good unity and is suitable for forming a proton conductive film interposed between electrodes of a polymer electrolyte fuel cell.

SOLUTION: The proton conductive resin composition which is a core/shell resin comprising a mixture of a carbon cluster having a proton-dissociating functional group and a vinylidene fluoride resin, wherein the vinylidene fluoride resin comprises a core part made of a vinylidene fluoride copolymer (a) and a vinylidene fluoride polymer (b) having a vinylidene fluoride content (wt.%) larger than that in the vinylidene fluoride copolymer.
