<P>PROBLEM TO BE SOLVED: To provide coating solution for forming a catalyst film for a fuel cell having high dispersibility, no risk of contact with platinum catalyst particles, and satisfying coating property such as no breakage or no repellency, film performance influencing on battery performance, and storage stability; and to provide the catalyst film for the fuel cell. <P>SOLUTION: The coating solution for forming the catalyst film for the fuel cell is manufactured in such a way that platinum catalyst particles are dispersed in water in which a polymer electrolyte is dissolved, and then an alcohol dispersion medium or an ester dispersion medium is added into the dispersed solution. The catalyst film for the fuel cell is manufactured by using the coating solution, and the catalyst film is used in the fuel cell. <P>COPYRIGHT: (C)2009,JPO&INPIT |
