FUEL CELLS BASED SYSTEM AND THE CONTROL DEVICE Russian patent published in 2019 - IPC H01M8/06 

FIELD: machine building.

SUBSTANCE: invention relates to the fuel cells based system and the control device. Fuel cells based system includes a pressure control unit, which is located in the supply path for the hydrogen supply and reduces supplied to the fuel cells battery hydrogen pressure, expansion device, which is located upstream of the pressure control valve in the supply path, and reduces the pressure and expands supplied from the hydrogen tank hydrogen, and the second control valve, which is located upstream of the expansion device in the supply path and is adapted to switch to one of the open state, in which the hydrogen is supplied to the expansion device, and the closed state, in which the hydrogen supply to the expansion device is interrupted or supplied to the expansion device hydrogen volume is less than volume in the open state. System also includes comprising the control unit control device, which controls the second control valve.

EFFECT: enabling the possibility of hydrogen expansion energy in the expansion device effective recovery.
