FUEL CELL SYSTEM Russian patent published in 2021 - IPC H01M8/4298 

FIELD: fuel cell systems.

SUBSTANCE: invention relates to the technology of a fuel cell system. The fuel cell system contains a fuel cell stack and a control device. The control increases the voltage in the fuel cell stack until a predetermined voltage condition is reached by supplying an oxidizing gas to the cathode before starting the supply of current, if the value measured by the temperature sensor is equal to or less than the predetermined temperature at the start of the fuel cell system. The controller performs standby control in which the current setpoint is held constant when the measured voltage value reaches the control start voltage value that is lower than the transient voltage setpoint, and ends the standby control by allowing the current setpoint to change when the measured voltage value reaches the value permissive voltage equal to or higher than the set voltage value during the backup control.

EFFECT: prevention of over-supply of current, control of the number of charge/discharge cycles of the battery, suppression of the formation of injection hydrogen.
