Abstract
An electrolytic cell for the production of hydrogen peroxide with faradic efficiency and a method for the production of highly pure hydrogen peroxide with high faradic efficiency are disclosed. The cell is provided with a separator of high hydraulic permeability and is equipped with an oxygen-fed gas-diffusion cathode and with an anode activated with a catalyst for oxygen evolution. The high faradic efficiency of hydrogen peroxide generation is allowed by the dilution of product hydrogen peroxide by the anolyte crossing the permeable separator, and by keeping the operating temperature at values below 50° C.
