Study of hydrogen accumulation in palladium, silver and silver-palladium alloy

This work present a results of investigation of the hydrogen accumulation characteristics in palladium, silver and palladium-silver alloy (Pd₆₀Ag₄₀) at their saturation with hydrogen from different aggregate states of the ambient medium (plasma, liquid, hydrogen atmosphere). The presence of silver in the alloy of palladium-silver leads to the following features: the capture of hydrogen by Pd and Pd₆₀Ag₄₀ samples depends on the method of saturation. In the case, while plasma and electrolytic hydrogen saturation in both samples is being trapped in the same type of traps (not significantly different in binding energy). While the saturation by Sieverts method takes place, traps formed are characteristic for each type of the samples. In case of electrolytic and plasma saturation in palladium and palladium-silver alloy, the main type of trap is the binding of hydrogen in palladium hydride. Alloying palladium with silver does not lead to a decreasing of sorption capacity of the alloy Pd₆₀Ag₄₀ compared to Pd.
