Abstract
Gas depolarized cathodes having hydrophobic barrier layers for circulation electrolyte electrochemical cells; methods of making said cathodes; and methods of electrolyzing solutions of halide containing compounds using said electrodes. Typically, in electrochemical cells cathodes are oriented vertically resulting in significant electrolyte pressure against the cathode. The barrier layer comprising fluorocarbon polymer and carbon results in substantially no electrolyte leakage through the cathode when the electrolyte pressure is up to three pounds per square inch above ambient.
