Patent ID: 8425754

Claim:
Cathode for electrolysis cell having an internal volume delimited by a foraminous conductive surface comprising two major faces suitable for being coated with a chemically inert porous diaphragm, said internal volume comprising at least an upper element and a lower element for distribution of fluids and electric current, each of said distributing elements comprising one plate of a first conductive material equipped on both faces of the plate with a multiplicity of bumps, the bumps on one face in electrical contact with one of said major faces of said conductive surface, and the bumps on an opposed face in electrical contact with an opposed major face of said conductive surface, and each of said distributing elements comprising one foot of a second conductive material, said foot of said upper element disposed in the bottom part and in electrical contact with one major face of said conductive surface, said foot of said lower element disposed in the top part, in electrical contact with the opposed major surface of said conductive surface and provided with a multiplicity of protrusions delimiting grooves for the passage of fluids, said feet of said upper and lower element facing each other at least partially.
