Efforts by trial and error between experimental measurements and theoretical approaches have been made to obtain electrochemical parameters of hydrogen evolution reaction occurred on aluminum in sulfuric acid solution. Polarization curves of aluminum in 0.01, 0.1 and 0.5 mol·dm-3 sulfuric acid solutions with dissolved oxygen-free and stagnant conditions were measured and analyzed by the polarization resistance method. The method reveals that the electrochemical characteristics of hydrogen evolution reaction on aluminum in sulfuric acid solution had the exchanged current density of i0=10-4.5 mA·cm-2 in 0.5 mol·dm-3 sulfuric acid solution, which generally corresponded with published data elsewhere.
