CATALYST COATED MEMBRANE (CCM) AND CATALYST FILM/LAYER FOR ALKALINE MEMBRANE FUEL CELLS AND METHODS OF MAKING SAME

摘要

Alkaline membrane fuel cells designed with silver cathode catalysts include a catalyst layer comprising silver metal nano-particles and an anion-conducting ionomer. The silver nano-particles are mixed with a solution of the ionomer to form a catalyst ink that is applied to an alkaline membrane to form an ultra-thin cathode catalyst layer on the membrane surface.
