MANUFACTURING METHOD OF ELECTROLYTE MEMBRANE FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an electrolyte membrane for a fuel cell which is superior in proton conductivity and which can retain mechanical strength of the membrane.

SOLUTION: This is the manufacturing method of the electrolyte membrane for the fuel cell including a process of irradiating radiation to a basic solid polymer film under existence of oxygen, and a process of doping a proton conductive compound to the radiation-irradiated basic solid polymer membrane.
