Abstract: The investigation of the electrolytic hydrogen evolution reaction on nickel has been carried out in both H2S04a nd HCl solutions, using permeation-potential and current-potential relationships as a diagnostic criterion for mechanism determination. The mechanism for hydrogen evolution reaction on nickel in both solutions, regardless of the addition of H2SeO3 is a "Slow discharge-fast recombination", not depending upon pH values. However, the experimental results could not distinguish that the mode of adsorption of hydrogen is either the Langmuir or Temkin type. The effect of addition of H2SeO3 may be aUributed not to so much the lowering the binding energy of M-Hads bond as the increase of the entropy change of adsorbed hydrogen atoms.
