Abstract
A fuel cell includes a plate-like cell, a separator on one side of the plate-like cell, and a separator on the other side of the plate-like cell. The plate-like cell includes a solid polymer electrolyte membrane, an anode, and a cathode. The anode has a stacked body composed of a catalyst layer and a gas diffusion layer. The cathode has a stacked body composed of a catalyst layer and a gas diffusion layer. The catalyst layer contains a porous carbon material formed with micro pores, which functions as an electric double layer, and an ion-exchange resin. At least part of the porous carbon material supports a catalytic metal such as platinum. The porous carbon material to be used is preferably a carbide-derived carbon. The carbide-derived carbon preferably has micro pores of 1 nm or less.
