ABSTRACT:
Disclosed is a water electrolysis process for producing hydrogen in which a nickel anode is prepared by an electrolytic corrosion procedure. This procedure reduces the anode overpotential by about 0.2 volts at commercially used current densities which leads to greater process efficiency and significant reduction in electrical energy consumption.
