ELECTROLYTIC CELL FOR PRODUCING HYDROGEN AND OXYGEN FROM WATER Russian patent published in 2017 - IPC C25B9/08 C25B1/10 

FIELD: chemistry.

SUBSTANCE: invention relates to an electrolytic cell for the production of hydrogen and oxygen from water, consisting of a casing with a cathode housed therein in the form of a hollow cylinder of a porous hydrophobic material and an anode in the form of a metal tube located between them in the form of a gas-stop membrane, gas cavity between the outer wall of the cathode and the inner wall of the casing, the anode cavity inside the anode, with the anode applied to the surface and the cathode surface by the catalyst. The cell is characterized in that an anode made of perforated metal sheet attached on the outer surface of the metallic mesh coated with a catalyst, a cathode made of a porous hydrophobised material coated on its outer surface by the hydrogen cavity catalyst and the inner side with attached to it mesh coated with a catalyst gas-closing separator consists of a porous membrane of a hydrophilic material, surrounded on both sides by one or more layers of the separating material, sealing the cavity relative to the cavity hydrogen oxygen is carried out in the assembly due to the cell as a flange made of insulating material and having a ring grooves with gaskets to create a seal along the ends of the cathode at the points of contact with the flanges, and by squeezing the upper and lower ends of the separator when the electrolyser is assembled, protruding beyond the anode and the grids attached to the cathode and anode, between the outer end conical surfaces of the corresponding flanges and corresponding to the inner end conical surfaces of the cathode.

EFFECT: use of the proposed device allows to minimize energy costs for own needs and, as a result, to increase the efficiency of the claimed cell, increase the reliability of the cell operation and the purity of the produced gases.
