WATER ELECTROLYSER AND OPERATION METHOD THEREOF Russian patent published in 2018 - IPC C25B1/12 C25B1/10 C25B9/08 C25B15/00 

FIELD: technological processes.

SUBSTANCE: invention relates to water electrolyzer comprising current source, control unit, sealed housing, on the external surface of which there is temperature sensor connected to control unit, device for maintaining temperature of hermetic body within predetermined limits, located in hermetic housing, porous hydrophilic membrane, two adjacent to it porous hydrophobic electrode – anode and cathode, connected to current source, two sealed partitions, one of which is connected to the end part of the anode and a sealed enclosure with the formation of an oxygen cavity between the outer surface of the anode, the partition and the inner surface of the hermetic housing, and the other – with the end part of the cathode and the hermetic case with the formation of a hydrogen cavity between the outer surface of the cathode, the partition and the inner surface of the hermetic housing, while between the partitions an electrolyte cavity is formed connected to the water supply line with the water filling valve, the hydrogen and oxygen supply lines with valves for their discharge from the respective cavities, gas differential pressure regulator connected to the discharge lines of said gases, and pressure sensor connected to the control unit. In this case, the inner surface of the hermetic body is covered with a layer of porous hydrophilic material, similar to the membrane material and having a hydraulic connection with the cavity of the electrolyte and with the membrane, and the sealed partitions are made flexible and elastic, and the elasticity of each partition is chosen such that, throughout the working range of its displacements the value of the elastic pressure on the electrolyte was lower than the capillary pressure of the membrane and a layer of a porous hydrophilic material. invention relates to a method of operating electrolysis unit.

EFFECT: technical result of the proposed invention is the simplification of the design of the water electrolyzer, as well as the deeper dehydration of gases.
