METHOD FOR WATER ELECTROLYSIS UNDER PRESSURE IN ELECTROLYSIS SYSTEM Russian patent published in 2015 - IPC C25B1/12 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for water electrolysis under pressure in an electrolysis system which includes accumulators operating with a working cycle closed through water. The method includes supplying dc voltage from a power supply and water; partial decomposition of the water with current during water electrolysis with separate generation of hydrogen and oxygen; separating said gases from water in gas separators while ensuring pressure equilibrium of said gases during the generation process and filling system vessels with the obtained gases, wherein generation of the gases and filling the vessels with said gases is carried out in turns, with pneumatic isolation of the gas separators of the system from the vessels when generating hydrogen and oxygen, and from the electrolysis cell when filling the vessels, wherein before filling the vessels the gas separators are isolated from each other and then reconnected after filling.

EFFECT: enabling generation of hydrogen and oxygen with the same pressure without power load on cell membranes and filling vessels of the electrolysis system with gases with different pressure without losing gases owing to a two-step operating algorithm of the electrolysis gas accumulator, ie time-separation of the processes of generating gases and filling vessels with said gases.
