Abstract The effect of the surface treatment by H3PW12O40 solution on electrochemical properties of the LaCo4.8Bi0.2 alloy was investigated. A significant increase of hydrogen absorption and a distinct increase of exchange current density was obtained for LaCo4.8Bi0.2 alloy activated with tungstophosphoric acid. Potentiokinetic polarization curves show that the anodic currents increase with the amount of absorbing hydrogen. Graphical abstract [...]
