Abstract
The cathodic injection, anodic extraction, and solid-phase diffusion of atomic hydrogen in the compact metallurgic Cu-Pd and Ag-Pd alloys in aqueous solutions 0.1 M H2SO4 are investigated by linear voltammetry and step controlled-potential multicycle chronoamperometry and chronopotentiometry. The basic kinetic characteristics of processes of hydrogenation of the studied alloyed systems at X Pd ≥ 30 at % are obtained. The weak effect of the nature of the electronegative component on the characteristics of the injection and extraction of atomic hydrogen is revealed. The contribution of irreversible sorption is no more than 6–12%.
