Abstract:
An electrolytic cell for the production of hydrogen peroxide solution and hypohalide by electrolysis, which comprises an anode chamber housing an insoluble anode capable of oxidizing halide ion; a cathode chamber housing a gas diffusion cathode capable of oxidizing an oxygen-containing gas to produce hydrogen peroxide, said cathode chamber is partitioned by said gas diffusion cathode into a solution chamber and a gas chamber, a gas chamber is arranged on a side of the solution chamber opposite the anode chamber, and the electrolytic cell comprises means for supplying seawater to the solution chamber; a membrane separating the anode and cathode chambers; and means for supplying water containing halide ion to the anode chamber and an oxygen-containing gas to the gas chamber, whereby an anolyte containing hypohalide is produced in the anode chamber and a catholyte containing hydrogen peroxide is produced in the cathode chamber.
