Electrochemical Energy Conversion in a Palladium Hydrogen Diffusion Electrode

摘要

A high efficiency palladium-hydrogen diffusion electrode has been developed. Current densities of 165 ma/cm are achieved at 30C on 0.010 inch wall electrodes after pretreatment by abrading and oxidizing in air at 800C. Hydrogen transport is governed by solid state diffusion. An equation for hydrogen diffusion in beta-pd has been determined: D(sub beta) = 3.8 x 0.0001 exp(-2930/RT). (Author)
