ELECTROCHEMISTRY OF FUEL CELLS ELECTRODES. HYDROGEN EVOLUTION AT DILUTE PLATINUM AND PALLADIUM AMALGAM ELECTRODES,

Abstract

The hydrogen overpotential and double-layer capacity of liquid amalgams containing 0.028 atom % platinum or 0.006 atom % palladium are identical with those for pure mercury. Triangular voltage sweep studies on the platinum amalgam give results identical with pure mecury, but the palladium amalagam shows behaviour which may result from the formation of colloidal palladium or of a palladium-hydrogen complex on the surface. These results imply that electro-catalysis of the hydrogen reaction by these metals is a cooperative phenomenon, rather than an independently additive, atomic one. (Author)
