DEVICE FOR WATER ELECTROLYSIS Russian patent published in 2020 - IPC C25B1/10 C25B9/10 

FIELD: chemistry.

SUBSTANCE: invention relates to three versions of a water electrolysis device. According to one version, the device comprises: a housing comprising a sidewall; electrolytic cell with ion-exchange membrane in housing, made with possibility of water electrolysis and hydrogen and oxygen release, wherein electrolytic cell with ion-exchange membrane comprises first side, second side corresponding to first side, an ion-exchange membrane, a cathode, an anode, a hydrogen discharge tube and an oxygen discharge tube, wherein the ion-exchange membrane is located between the cathode and the anode; and a built-in water reservoir module for housing inside the housing and connected to the electrolytic cell with the ion-exchange membrane, wherein the built-in water reservoir module comprising a water reservoir, is configured to supply water into the electrolytic cell with the ion-exchange membrane; wherein when electrolytic cell with ion-exchange membrane performs water electrolysis, hydrogen is released at cathode, which is discharged through the hydrogen discharge tube, and oxygen is released at the anode, which is discharged through the oxygen discharge tube; wherein the hydrogen outlet tube and the oxygen discharge tube are connected to the electrolytic cell second side with the ion-exchange membrane, and hydrogen and oxygen are removed from second side of electrolytic cell with ion-exchange membrane; wherein built-in module of water tank receives hydrogen and oxygen, extracted by electrolytic cell with ion-exchange membrane through hydrogen outlet tube and oxygen discharge tube respectively.

EFFECT: invention is efficient with respect to use of space and has low noise.
