A Mechanistic Analysis of Hydrogen Entry into Metals during Cathodic Hydrogen Charging

Abstract

A summary of a recently completed analysis of hydrogen electrode reactions during aqueous cathodic charging of metals is presented. The analysis for the first time takes into account the effect of hydrogen permeation into the metal of the h.e.r. From the model, all of the kinetic parameters are computable without use of any adjustable parameters. For the first time, surface coverages and rate constants are determinable from the measured charging and permeation currents. The enhancement of hydrogen entry in the presence of poisons, such as hydrogen sulfide, can be analyzed with the model, taking into account the Frumkin-Temkin isotherms in the discharge and recombination reaction kinetics. Keywords: Electrochemistry; Hydrogen evolution reaction; Permeation flux; Charging flux. Reprints.
