A fuel cell system includes a fuel cell, a first temperature sensor configured to acquire a first temperature that is a temperature of the fuel cell, a plurality of accessories that is used to operate the fuel cell, a second temperature sensor configured to acquire a second temperature that is a temperature of at least any one of the plurality of accessories, and a controller configured to perform control on the plurality of accessories to execute a warming-up operation of the fuel cell. The controller is configured to execute the warming-up operation when any of a first condition that the first temperature is lower than a predetermined first threshold temperature and a second condition that the first temperature is equal to or higher than the first threshold temperature and the second temperature is lower than a predetermined second threshold temperature is satisfied.

Fuel cell system

A fuel cell system includes: a fuel cell that is supplied with a reaction gas to generate electricity; a plurality of auxiliary components used for power generation of the fuel cell; and a control device that causes the fuel cell to generate electricity when a predetermined scavenging start condition is satisfied and controls the auxiliary components using electric power generated by the fuel cell to perform a scavenging process of removing water in a flow path of the reaction gas using the reaction gas, during a stop period in which electric power is not supplied to a load from the fuel cell system.

A fuel cell system includes a fuel cell stack, a temperature measurement unit, and a controller. The controller is configured to, when the stack temperature is equal to or lower than a predetermined first threshold temperature at the time of startup of the fuel cell system, control a heat generation amount per unit time of the fuel cell stack to a set heat generation amount to perform a warming-up operation until the stack temperature increases to a target temperature, and when the stack temperature is equal to or higher than a predetermined second threshold temperature, execute at least one of setting the target temperature to be lower than the target temperature when the stack temperature is lower than the second threshold temperature and setting the set heat generation amount to be smaller than the set heat generation amount when the stack temperature is lower than the second threshold temperature.
