METHOD OF OPERATING HIGH-PRESSURE ELECTROLYSIS SYSTEM Russian patent published in 2016 - IPC C25B1/12 C25B15/02 

FIELD: chemistry.

SUBSTANCE: method of operating a high-pressure electrolysis system includes a process of decomposing water with electric current with separate generation of hydrogen and oxygen; collecting the obtained gases in containers with a volume ratio of 2:1, respectively, and measuring the pressure of said gases; after measuring the pressure of oxygen $$P_{O_2},$$ increasing the volume $$V_{H_2}$$ of the hydrogen container to a value defined by the relationship: $$V_{H_2}=\frac{V_{O_2}{\rho }_{O_2}}{8{\rho }_{H_2}},$$ where $$V_{O_2}$$ is the volume of the oxygen container; $$V_{H_2}$$ is the volume of the hydrogen container; $${\rho }_{O_2}$$ is the density of oxygen at pressure $$P_{O_2}$$ (in the oxygen container); $${\rho }_{H_2}$$ is the density of hydrogen at pressure $$P_{O_2}$$ (in the hydrogen container).

EFFECT: ensuring reliable pumping into hydrogen and oxygen cylinders at high pressure while maintaining balance of pressure of said gases during electrolysis.
