An electrolytic cell has a carboxylic acid permionic membrane 33 interposed between the anolyte NaCl and catholyte H2O, the membrane having electrocatalytic anode 35 and an electrocatalytic cathode 41 on opposite faces thereof. The cathode may be a depolarized cathode, e.g., a peroxy compound depolarized cathode, a redox couple depolarized cathode, or an oxidant- complex depolarized cathode. The cathode may be a boride, e.g., titanium, diboride, an intercalation compound of carbon and fluorine, or a transition metal, e.g., iron, cobalt, or nickel. The electrocatalysts, may be adhered to the permionic membrane by chemdeposition. The anode may be particulate with hydrophobic material. The individual anode particles may be silicon extended. The electrolytic process may be carried out at high pressure whereby to obtain liquid chlorine, which is then separated from the brine. The cell may be horizontal, with internal heat exchange means. In the case of a bipolar cell, the bipolar conductor element may be silicon, or a titanium alloy, and may have heat transfer and reagent feed means incorporated therein. <IMAGE> |
