  • Patent number: 11539062
    Abstract: A fuel cell system includes a fuel cell, a fuel gas supply channel, a regulator, an injector, and a controller. The controller drives the regulator in conjunction with the injector. The controller compares a fuel gas flow amount necessary for the fuel cell to generate electricity with a predetermined fuel gas flow amount, selects the fuel gas flow amount that is larger, and issues commands to the regulator and the injector. The predetermined fuel gas flow amount is set to be larger than the fuel gas flow amount necessary for the fuel cell to generate the electricity when a generated current or output of the fuel cell is smaller than a predetermined threshold value.
