Electrochemical properties of Ni-Pd Electroplatings at evolution of hydrogen and oxygen in acid and alkaline environments

Abstract

There are actually important based on the technical-economical analysis questions of creation of highly effective bipolar electrodes, electrode-diaphragm blocks with zero-gap for alkaline electrolyzes, and from there are questions of replacement of expensive oxygen Pt-Ir electrode and the cathode with the platinum electrocatalyst for membrane electrolyzes. The work purpose was plating and investigation of electrocatalytical and hydrogen sorption properties of galvanic Ni-Pd coverings on various substrates. The Ni-Pd coverings were obtained from ammonium-chloride and ammonium-sulfuric-chloride electrolytes.
