A method of replacing a gas in a fuel cell system is provided, which comprises the steps of detecting that a fuel cartridge is connected to the fuel cell system having a fuel cell and supplying a fuel from the fuel cartridge on the basis of the detection to start replacement of gas in the fuel cell system.

Especially, a user does not have to perform the gas replacement operation manually. The gas replacement can be automatically performed.
