Abstract
A method and apparatus for water electrolysis is described, using an electrolytic cell comprising an anode compartment, a cathode compartment, and a diaphragm separating the anode and cathode compartments, comprising the steps of electrolyzing water to evolve oxygen or an ozone-containing oxygen gas in the anode compartment and hydrogen in the cathode compartment, thereby resulting in a net transfer of electrolyte from the anode compartment to the cathode compartment through the diaphragm, and recycling electrolyte from the cathode compartment to the anode compartment.
