Patent ID: 8591719

Claim:
An electrolysis cell for hydrogen peroxide production comprising: a cathodic compartment, the cathodic compartment comprising: a gas-diffusion cathode comprising a catalytic porous film for the reduction of oxygen to hydrogen peroxide, means for feeding oxygen, and a bottom part adapted to withdraw a solution of hydrogen peroxide of 1 to 5% by weight concentration; an anodic compartment, the anodic compartment comprising: an anode equipped with a catalyst for oxygen evolution, and means for feeding an aqueous anolyte; and a membrane subdividing the cell into the cathodic compartment and the anodic compartment, the membrane being an ionomer membrane having an equivalent weight below 700 and provided with a first surface facing the cathodic compartment and a second surface facing the anodic compartment, wherein, the catalytic porous film of the gas-diffusion cathode comprises at least one hydrophobic material, at least one hydrophilic material and at least one catalytic material and has a bimodal internal structure comprising hydrophobic micro-regions and hydrophilic micro-regions.
