APPARATUS FOR ELECTROLYSIS OF WATER UNDER PRESSURE AND METHOD FOR OPERATION THEREOF Russian patent published in 2014 - IPC C25B1/12 C25B1/02 C25B1/04 C25B9/00 

FIELD: chemistry.

SUBSTANCE: invention relates to an apparatus for electrolysis of water under pressure, which consists of an electrolysis cell with a water feed line connected to a supply unit, which is electrically connected to a control unit, receivers connected to the electrolysis cell through hydrogen and oxygen lines for accumulating hydrogen and oxygen, said receivers being fitted with hydrogen and oxygen pressure sensors, electrically connected to the control unit, valves for releasing hydrogen and oxygen from the apparatus fitted on the hydrogen and oxygen lines; each receiver is equipped with a water filling line, a water draining line and a sensor for measuring the amount of water, wherein the water filling and draining lines are fitted with valves, and the sensor for measuring the amount of water and the valves on the water draining lines are electrically connected to the control unit. The invention also relates to a method of operating the apparatus for electrolysis of water under pressure, which involves feeding water and electric current to the electrolysis cell, accumulating hydrogen and oxygen in the receivers, monitoring process parameters, levelling gas pressure and delivering the obtained gases to a consumer, wherein before the beginning of the operating cycle, the hydrogen and oxygen receivers are filled with water in amount of 15% to 30% of the volume of the corresponding receiver, and during operation, the amount of water is controlled, hydrogen and oxygen pressure is recorded and if the pressure drop of hydrogen and oxygen exceeds an allowable value, water is drained from that receiver where gas pressure is higher until pressure in the receivers levels.

EFFECT: increasing cost-effectiveness of the apparatus by 15-20% by preventing loss of gases, high safety of operation by eliminating the possibility of mixing gases.
