Patent ID: 10497995

Abstract:
There is provided a fuel cell system. When receiving an instruction to start power generation of the fuel cell system, the fuel cell system is configured: (i) to obtain an output limit value of a secondary battery according to a predetermined relationship of a temperature of the secondary battery to the output limit value of the secondary battery by using the temperature of the secondary battery; (ii) to control a battery converter such as to increase a voltage of a smoothing capacitor for boosting included in the battery converter to a start-time target voltage that is higher than an open circuit voltage of a fuel cell, such that an output power of the secondary battery does not exceed the output limit value; and (iii) to operate the compressor such as to start supplying the cathode gas by the cathode gas supply system and to open the main stop valve such as to start supplying the anode gas by the anode gas supply system.
