Abstract:
1. A method for controlling a fuel cell system having a fuel cell to generate power according to an electrochemical reaction of an oxide gas supplied to a cathode side with a fuel gas supplied to an anode side, an oxide-gas supply apparatus to supply the oxide gas to the fuel cell, and a fuel-gas supply apparatus to supply the fuel gas to the fuel cell, the method comprising: an in-stop-mode power generating process of, when an operation stop instruction to stop an operation of the fuel cell is detected, stopping supply of the fuel gas from the fuel-gas supply apparatus to the fuel cell, supplying the oxide gas to the fuel cell to generate power from the oxide-gas supply apparatus, and stopping power generation of the fuel cell; and a first startup process performed when a pressure of the anode side is equal to or lower than a first threshold pressure of, when an operation start instruction to start the fuel cell system is detected after the in-stop-mode power generating process, starting supplying the fuel gas from the fuel-gas supply apparatus to the fuel cell, and starting supplying the oxide gas from the oxide-gas supply apparatus after the starting of supply of the fuel gas.
