PROTON-CONDUCTIVE ELECTRODE, PROCESS FOR PRODUCING THE SAME, AND ELECTROCHEMICAL DEVICE

A proton conducting electrode useful for a fuel battery. The proton conducting electrode is comprised of a mixture including a fullerene derivative and an electron conducting catalyst, wherein the fullerene derivative is composed of carbon atoms forming fullerene molecules and a proton (H) dissociating group introduced into said carbon atoms. This proton conducting electrode is manufactured by coating mixture containing the fullerene derivative and the electron conducting catalyst on a gas transmitting current collector.
