FUEL CELL SYSTEM

摘要

An object is to perform a purge at an appropriate timing. There is provided a fuel cell system mounted on a vehicle. The fuel cell system comprises a gas supplier that is configured to supply a purge gas into a fuel cell; and a controller that is configured to control the gas supplier and perform a purge with the purge as at a stop time of the vehicle. The controller obtains an ambient temperature in a driving state of the vehicle a plurality of times. In a case where an ambient temperature obtained last time among the ambient temperatures obtained in the driving state is lower than a predetermined reference value, the controller performs the purge with enhancing a purging capacity, compared with a case where the ambient temperature obtained last time is higher than the predetermined reference value.

1. A fuel cell system mounted on a vehicle, comprising:
a fuel cell; an ambient temperature sensor configured to obtain a temperature outside of the vehicle as an ambient temperature; a gas supplier configured to supply a purge gas into the fuel cell; and a controller configured to control the gas supplier and perform a purge operation to purge the fuel cell with the purge gas, wherein the controller obtains an ambient temperature in time series from the ambient temperature sensor in a driving state of the vehicle where the vehicle has a non-zero vehicle speed, the controller performs the purge operation after an off operation of a start switch of the vehicle, and in a case where an ambient temperature obtained last time among the ambient temperatures obtained in time series is lower than a predetermined reference value, the controller performs the purge operation after the off operation of the start switch with enhancing a purging capacity, compared with a case where the ambient temperature obtained last time is higher than the predetermined reference value.
