REGENERATIVE ELECTROCHEMICAL POWER SUPPLY SYSTEM OF MANNED SPACE VEHICLE WITH WATER-CLOSED WORK CYCLE AND METHOD OF SYSTEM OPERATION Russian patent published in 2014 - IPC H01M8/00 H01M8/06 C25B1/04 

FIELD: electricity.

SUBSTANCE: regenerative electrochemical power supply system of a manned space vehicle with water-closed work cycle includes a water electrolyser and an oxygen-hydrogen generator interconnected hydraulically through a water collection tank and interconnected pneumatically with hydrogen and oxygen storage cylinders, the latter of which is connected to the space vehicle life support system by an air-pressure line with a gate, a metal-hydrogen accumulator having a union for hydrogen through which it is connected to the hydrogen storage cylinder by an air-pressure line with a gate. The operating method of the above system includes a closed cycle of water decomposition by current into hydrogen and oxygen, stoichiometric compounding of these gases with production of electricity and water and off-take of oxygen from this cycle, excess of hydrogen is used as a reagent in the metal-hydrogen accumulator which is charged preliminary with removal of hydrogen formed in it during charging.

EFFECT: maintenance of energy intensity, disposal of excess hydrogen, increase of the system safety.
