FUEL CELL SYSTEM Russian patent published in 2021 - IPC H01M8/04 

FIELD: fuel cell systems.

SUBSTANCE: invention relates to the technology of a fuel cell system. The fuel cell system includes a fuel cell stack and a control device that controls the operation of the fuel cell system based on a measured voltage value measured by a voltage sensor. If, when starting the fuel cell system, the value measured by the temperature sensor is equal to or less than the predetermined temperature, the control device increases the voltage of the fuel cell stack until the predetermined voltage condition is reached by applying an oxidizing gas to the cathode before starting the current supply. The controller sets the voltage setpoint and current setpoint such that the operating point of the fuel cell stack is on the constant energy line of the fuel cell stack when the operating point makes a transition for at least a portion of the transition period.

EFFECT: regulation of the number of charge/discharge cycles of the secondary battery in a certain range, while reducing the possibility of the formation of injection hydrogen.
