Abstract: A fuel cell system includes a microprocessor configured to perform, during an external power supply in which power is supplied to an external load, controlling a power generation of a fuel cell so as to generate a power at a predetermined power generation efficiency and supplying a surplus power not consumed out of the generated power of the fuel cell to a battery to charge the battery. The controlling includes, during the external power supply, stopping the power generation of the fuel cell when a charge rate of the battery becomes a first predetermined value or larger, controlling an output of the battery so that the power of the battery is supplied to the external load, and resuming the power generation of the fuel cell when the charge rate becomes a second predetermined value smaller than the first predetermined value or lower.
