ELECTROLYTE FILM FOR FUEL CELL AND ITS FORMING METHOD, FUEL CELL AND ITS MANUFACTURING METHOD, AND SOLID POLYMER-MODIFIED ELECTRODE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an electrolyte film low in cost and excellent in water-resisting property and methanol-resisting property, and a manufacturing method for a fuel cell using it.

SOLUTION: Aromatic hydrocarbon polymers are denatured by sulfonic acid groups, sulfoalkyl groups, carboxyl groups, or phosphoric acid ester groups, and modified by the irradiation of ionizing radiation.
