Abstract

An electrolytic cell having first (14) and second (10) electrode structures in which the first electrode structure has a surface area (28) which is in heat transfer relation with the electrolyte and part only of said surface area (18) is electrolytically active. The first electrode structure may be an anode structure suitable for use in the production of ozone and the remaining part (28) of the surface area of the anode structure may be rendered electrolytically inactive by masking this part from the cathode structure. The masked surface of the anode structure is maintained in heat transfer relation with the electrolyte.
