The present invention provides a fuel cell system capable of improving the power generation performance of the fuel cell stack by reducing the flow rate of circulating gas during high-temperature operation to suppress drying in the fuel cell stack. The fuel cell system includes a fuel cell stack, an injector, a first injector that supplies fuel gas to the injector, and a first injector that supplies the fuel gas to the injector and has a smaller injection amount of the fuel gas than the first injector. 2 injectors, a third injector for supplying the fuel gas to each of the fuel electrodes of the fuel cell stack, a fuel gas supply unit, a first supply flow path, and a fuel gas supply unit capable of injecting the fuel from the third injector to the fuel cell stack A second supply flow path for supplying the fuel gas, a circulation flow path, a temperature detection unit, and a control unit are provided. |
