Abstract (en)

[origin: US4455203A] Hydrogen peroxide, H2O2, is electrochemically produced from water or an aqueous solution and oxygen in an electrolytic cell using a solid electrolyte (1) made of a perfluorinated polymer and gas-permeable coatings (2,3) as electrodes by supplying the water to the anode side and the oxygen to the cathode side and withdrawing the H2O2 on the cathode side. In this process, the oxygen produced on the anode side can also be made use of by passing it round to the cathode side or passing it through the solid electrolyte (1) in any such case where no undesirable gas (for example chlorine) is simultaneously formed at the anode. The process works largely independently of the cation concentration (salts, bases) and does not require an additional separation of the H2O2 from a liquid electrolyte.
