We study the corrosion behavior of electrode materials in the alkaline-water electrolysis within a broad range of electrolyte concentrations and for electrodes of different nature. It is discovered that the use of steel materials with low contents of chromium and vanadium impurities (0.1–0.3%) increases the corrosion resistance of the electrodes and weakens the dissolution of iron of steel anodes. The operation of anodes made of aluminum- and zinc-based alloys is accompanied by their dissolution. This fact makes it possible (due to the depolarization of the anodic process) to exclude the oxygen release by the mechanism of hydrogen depolarization, substantially simplify the technology of electrochemical synthesis of hydrogen, and to reduce the losses of materials and energy for the electrolysis.
