Cyclic voltammetry, quasipotentiostatic linear polarization and electrochemical impedance spectroscopy were methods used in the study of electrocatalytic activity of the Ni-28Mo electrode for the hydrogen evolution reaction. The measurements were performed in a 0.5 mol dm -3 NaOH solution at a temperature of 20 ̊C. The cyclic voltammogram was recorded over a wide range of intervals and clearly shows the potentials that lead to the formation and reduction of metal oxides and hydroxides. Electrocatalytic activity of the electrode is expressed by the catalytic parameters of the current density exchange j 0 and the Tafel cathodic slope b k which were determined by quasipotentiostatic linear polarization and electrochemical impedance spectroscopy. Using a modified Randles equivalent electric circuit, spectra obtained by electrochemical impedance were matched, and roughness of the electrode was determined from the value of the double layer capacity using Brug equation. The obtained impedance results were matching with the results of quasipotentiostatic linear polarization, and the Tafel slopes confirmed that the hydrogen evolution reaction takes place according to Volmer-Heyrovski mechanism and that the speed of the overall reaction is determined by the Heyrovski reaction.
