    摘要: Disclosed is a method of electrolyzing an aqueous alkali metal chloride, which method comprises passing an electrolytic current from an anode of an electrolytic cell through an alkali metal chloride electrolyte to a cathode of the cell, evolving chlorine at the anode and hydrogen at the cathode. The method is characterized by the use of a cathode having a layer of an oxy-compound of a platinum group metal and an alkaline earth metal on an electroconductive cathode substrate.

    摘要: Disclosed is a method of operating an electrolytic cell having an active, catalytic cathode and an iron structure in contact with an alkaline electrolyte. The dissolution of iron into the electrolyte is reduced by a sacrificial anode in proximity to, and preferably in contact with, the iron structure.
