Abstract
A fuel-cell electrode and a method of manufacturing the fuel-cell electrode achieves a high catalyst utilization ratio and makes it possible to obtain higher output characteristics with a smaller amount of catalyst. The fuel-cell electrode includes a catalytic layer composed of an ion conductive substance, an electron conductive substance and catalytic activation substances. The catalytic activation substances are electrolytically deposited on the electron conductive substance.
