A fuel cell system includes: a reaction gas supply unit configured to supply a reaction gas to a fuel cell stack; a humidifier configured to transfer moisture from an off-gas discharged from the fuel cell stack to the reaction gas; and a controller configured to control the reaction gas supply unit so as to regulate a supply amount of the reaction gas, wherein the controller is configured to acquire a temperature of the humidifier and set the supply amount of the reaction gas based on a target power generation amount of the fuel cell stack, and in a case where the temperature of the humidifier is equal to or lower than a prescribed warm-up determination value, the controller executes warm-up control to increase the supply amount of the reaction gas as compared with a case where the temperature of the humidifier is higher than the warm-up determination value.

Fuel cell system

An ECU of a fuel cell system determines whether or not temperature information exceeds a temperature threshold for determination when receiving a signal related to power generation stop of a fuel cell stack during operation of a moving body. When the temperature information exceeds the determination temperature threshold, the ECU performs a stop control for stopping power generation of the fuel cell stack. On the other hand, when the temperature information is equal to or lower than the determination temperature threshold, the ECU performs an idle control for generating electric power smaller than electric power consumed by the air pump.
