摘要：A method of reducing the overvoltages for hydrogen and oxygen evolution inalkaline water electrolyzers while preventing displacement of the potential of
electrically-floating cell components to a region where they are susceptible to corrosionis disclosed. The method comprises adding to the electrolyte between 0.01 and 10 gpl ofvanadium ions and controlling the potential of the electrically-floating cell componentsso as to maintain such potential out of the region where corrosion cracking may occur bysimultaneously adding between 0.1 and 20 gpl chromium ions to the electrolyte, or byusing an electrical circuitry requiring no external source of power.
