Abstract

An electrolytic cell comprises an anode plate, a cathode plate, and a permeable membrane interposed between the anode and cathode plate. An anode sealing gasket is interposed between the anode plate and the permeable membrane forming an anode chamber, the anode sealing gasket may comprise a bipolar electrode. A cathode sealing gasket is interposed between the cathode plate and the permeable membrane forming a cathode chamber. An anolyte reservoir external to the anode chamber supplies anolyte to and removes mixed oxidant gases from the anode chamber. An anolyte make-up tank external to the anolyte reservoir and anode chamber supplies anolyte solution to the anolyte reservoir. The anolyte solution is transferred from the anolyte make-up tank, to the anolyte reservoir, and into the anode chamber by gravity. A catholyte reservoir external to the cathode chamber supplies catholyte to and removes gases from the cathode chamber. The catholyte in the catholyte reservoir is transported into the cathode chamber by gravity. A voltage is applied between the anode and cathode plate to effect electrolysis reactions in each chamber producing the desired quantity and proportion of mixed oxidant g…
