MANUFACTURING METHOD OF ION-EXCHANGE MEMBRANE ELECTRODE JUNCTURE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of an ion-exchange membrane electrode juncture which can be made to hold enough amount of catalyst metal by absorption reduction method in the case of an electrode carrier applied water repellent treatment used for an ion-exchange membrane electrode juncture for a fuel cell. SOLUTION: A juncture of a water-repellent porous body and cation exchange membrane contacts the mixed solution of alcohol containing cationic complex of platinum and water, and then, contacts the mixed solution of alcohol containing hydrogenated boron compound and water.
