A gas diffusion electrode for an electrochemical cell and a fuel cell employing the electrode are disclosed. The electrode includes a porous body in contact with a catalyst layer comprising (i) a catalyst dispersed on the surface of a carbon support; (ii) a water-insoluble sulfonated polystyrene, poly( alpha -methylstyrene) or SEBS block copolymer; and (iii) a nonionic fluorocarbon polymer. The fuel cell includes two of the foregoing electrodes and a membrane of a proton-conducting polymer between the electrodes. It also includes an inlet for a gaseous fuel, an inlet for an oxygen-containing gas, and an outlet for reaction products.
