PROBLEM TO BE SOLVED: To aim at enhancing a performance of a solid polyelectrolyte-type fuel cell, in which an adequate three-phase interface is formed to a deep portion of an electrode, by using a composite catalyst, in which a water retention does not occur. SOLUTION: In the solid polyelectrolyte-type fuel cell, the catalyst particles are carbon supporting a catalytic metal, and the surface of the catalyst particles are comprised of the first resin and the second resin. A composite catalyst in which the first resin is an ion-exchange resin, and the second resin is a porous composite catalyst, or a composite catalyst, in which the second resin is non- porous and at least a part of the catalyst particle surface is not covered by the second resin, is used. |
