... is advisable to use Fe or Ni as a passive electrode. The overvoltage of hydrogen evolution on Ni is 210 mV, and on Fe is 80 mV (see Table 1). The low overvoltage of hydrogen and oxygen evolution at the passive Ni-electrode allows obtaining these gases directly from the very beginning of the electrochemical decomposition of the water (current density from 200 A/m 2 to 600 A/m 2 ). ...
