A fuel cell system includes a fuel cell which has a catalyst layer therein and which receives supply of a reactive gas to generate power, and a refrigerant system which supplies a refrigerant to the fuel cell to control its temperature. A method for stopping an operation of the system is also provided. When operated in a low-temperature environment, the system cannot be restarted due to freezing in the fuel cell. When the temperature of the fuel cell during the next system start is a predetermined temperature or less, the supply of the refrigerant is stopped during the system stop, and the supply of the refrigerant is resumed after elapse of a predetermined time. |
