Apparatus for electrolytic ozone generation

Abstract

An electrolytic ozone generating apparatus comprising a closely adhered electrode structure of (i) an anode composed of an electrically conductive porous material carrying an ozone generating catalyst, (ii) a perfluorocarbonsulfonic acid ion-exchange membrane which is a solid electrolyte, and (iii) a cathode composed of a gas electrode carrying a catalyst, and means for supplying an oxygen-containing gas to the cathode side, wherein the gas electrode as the cathode has a hydrophilic property and a hydrophobic property and carries a catalyst unevenly distributed therein at the ion-exchange membrane side, and a process for generating ozone using the apparatus. The electrolysis is conducted while supplying an oxygen-containing gas to the cathode side.
