ELECTROLYTE FILM FOR FUEL CELL CONSISTING OF FLUORINE POLYMER ION EXCHANGE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a fluorine polymer ion exchange membrane excellent in characteristics as a solid polymer electrolyte and in oxidation resistance, for one by radiation graft.

SOLUTION: With the fluorine polymer ion exchange membrane with a sulfonic acid group introduced to a double bond of a graft chain after radiation graft polymerization of fluorinated butadiene with a fluorine polymer film base material, and its manufacturing method, a graft ratio is 10 to 150%, and an ion exchange capacity is 0.3 to 3.0 meg/g.
