Abstract The potentiostatic pulse method was used to study the electrochemical evolution of hydrogen on polycrystalline iron electrodes in concentrated KOH solutions. It was found that in pure KOH solutions there appeared to be two reaction mechanisms for hydrogen evolution, one at high the other at low overpotentials. The addition of Li+, at constant hydroxide ion concentration, altered the kinetic parameters of these two mechanisms. Furthermore in pure LiOH only one reaction mechanism for all overpotentials was observed.
