Abstract
Disclosed is a method of electrolyzing alkali metal chloride brines by passing an electrical current from an anode in an aqueous alkali metal chloride anolyte liquor through a permeable barrier to a cathode in an aqueous catholyte liquor, whereby to evolve chlorine at the anode and hydrogen at the cathode. Also disclosed is the addition of a compound of an electrolytic hydrogen evolution catalyzing transition metal to the catholyte liquor while passing electrical current from the anode to the cathode. The addition of the compound of the transition metal through the catholyte liquor causes a reduction in the cell voltage.
