Electrolytic production of ozone by a process wherein an oxygen-saturated mixture of water and oxygen, or air, is led along both sides of a solid electrolyte (1), which acts as an ion-exchange membrane and carries coatings (2,3) of electrically conductive materials, both on the cathode side and on the anode side, ozone being evolved, in addition to oxygen, on the anode side and, on the cathode side, the evolution of hydrogen being suppressed by the depolarizing effect of the oxygen which is entrained in the water stream, and merely water being formed. The electrolysis is carried out under an increased pressure. Individual electrolysis cell bounded by bipolar plates (6), and comprising a solid electrolyte (1), provided, in each case, with a surface coating (2,3), and centrally located between current-collectors (4) and adjoining open metallic structures (5). A plurality of individual cells integrated together between end plates (7), electrically connected in series and hydrodynamically connected in parallel, combined to form a block. Use in water-treatment, and as a component of chemical processes (oxidation processes).

Process for the synthetic production of ozone by electrolysis, wherein water saturated with oxygen is used as starting material and, as the electrolyte, a solid electrolyte is used, which is coated with platinum on the cathode side and with PbO2 on the anode side and is in the form of a thin cation exchange membrane, wherein the oxygen-saturated water is led along, both on the cathode side and on the anode side, parallel to the solid-electrolyte membrane, and wherein the current supply to the coatings of the solid electrolyte, which serve as electrodes, is effected, in each case, via an open metallic structure having a low flow-resistance for the water, and wherein the water is simultaneously utilized for removing the heat generated during the process.
