Abstract

Constant current electrolysis of molten CaCl2-NaCl (70-30 mol %) containing CaO and AgCl at 953 K was carried out with a Pt gas anode and a carbon cathode. A novel concept was tested of introducing an oxidizable gas, hydrogen, to depolarize the Pt anode, resulting in the anode potential, and hence the cell voltage, decreasing by 0.3 V when the anode was fed with hydrogen.
