Abstract
The effect of electrolyte composition and cathodic current density (i( cat)) on the hydrogen permeability of electrochemically hydrogenated p alladium was studied. Hydride beta-phase PdH0.706 was shown to form in palladium as a result of this hydrogenation, the phase content being dependent on the pH of the electrolyte. At T = 292 K, hydrogen permeab ility of palladium membranes increases with increasing i(cat) and pH.
