Patent ID: 7670472

Claim:
Electrolysis cell for an electrochemical process comprising an anodic compartment comprising an anode and a cathodic compartment containing a cathode separated by an ion-exchange membrane, at least one of the compartments containing an assembly consisting of a current distributor connected to the wall of the relative compartment by means of supports, a gas diffusion electrode in contact with the surface of the current distributor, means for feeding said gas-diffusion electrode with gas located in the lower part of the cell, means for discharging the exhausted gas from the gas-diffusion electrode located in the upper part of the cell, and a planar porous element made of a hydrophobic plastic material selected from the group of high density polyethylene and fluorinated plastics inserted between said membrane and said gas-diffusion electrode and adapted to be fed with at least one liquid reactant percolating in its interior.
