粉体状触媒物質とその製造方法およびそれを用いた固体高分子型燃料電池電極

Document Type and Number:

Japanese Patent JP5108199

Kind Code:

B2

Abstract:

The battery performance of a solid polymer fuel cell is enhanced by improving a three-phase interface. A catalyst carrier conductive material 10, solid polymer electrolyte 20 and 30, and a good solvent and a poor solvent with respect to the solid polymer electrolyte are mixed so as to prepare an ink in which at least part of the solid polymer electrolyte is colloidalized. The ink is then dried to produce a powder catalytic material 40, which is applied to an electrolyte membrane or a gas diffusion layer, thereby forming a catalyst layer of an electrode.
