Abstract
A method of making electrodes using a solid polymer electrolyte base member and catalyst is disclosed. Before the catalyst is deposited upon the surface of the solid polymer electrolyte, the surface is treated by a suitable abrading or roughening means which contacts the surface of the solid polymer electrolyte base member in at least two directions. In a preferred mode, the solid polymer electrolyte membrane is abraded with a silicon carbide sheet to provide the desired roughness. The catalyst is deposited upon the roughened or abraded surface and fixed thereto by suitable means, e.g., pressure and/or heat. By this method, substantially reduced loadings of catalysts are possible. Solid polymer electrolyte catalytic electrodes made by this method are superior to prior art electrodes having substantially higher catalytic loadings when used as anodes in water electrolysis.
