Abstract
Disclosed is an electrode structure for ozone production which comprises a perfluorocarbon sulfonic acid-based ion-exchange membrane as a solid electrolyte and an anode placed on one side of the solid electrolyte and having a lead oxide as an electrode catalyst, wherein a porous, perfluorocarbon sulfonic acid-based ion-exchange resin layer is formed between the electrolyte and the anode. A process for producing the electrode structure for ozone production is also disclosed, which comprises coating one side of a perfluorocarbon sulfonic acid-based ion-exchange membrane as a solid electrolyte with a liquid, perfluorocarbon sulfonic acid-based ion-exchange resin or with a suspension of ion-exchange resin powder, heating-treating the liquid or suspension-formed ion-exchange resin coating to form an ion-exchange resin layer, and then positioning an anode so as to keep it in close contact with the ion-exchange resin layer, the anode having a lead oxide as an electrode catalyst.
