This invention relates generally to a process and apparatus for producing halogens by the electrolysis of aqueous halides in a cell having an oxygen depolarized cathode
Chlorine electrolysis cells which include ion transporting barrier membranes have been previously used to permit ion transport between the anode and the cathode electrodes while blocking liquid transport between the catholyte and anolyte chambers. Chlorine generation in such prior art cells have, however, always been accompanied by high cell voltages and substantial power consumption.
