Abstract:
1. A scavenging method for a fuel cell system, the fuel cell system comprising: a fuel cell for performing power generation by electrochemical reactions of an oxygen-containing gas and a fuel gas supplied to the fuel cell, an oxygen-containing gas flow field being formed in the fuel cell for supplying the oxygen-containing gas to the cathode, a fuel gas flow field being formed in the fuel cell for supplying the fuel gas to the anode, an oxygen-containing gas supply apparatus for supplying the oxygen-containing gas to the oxygen-containing gas flow field; a fuel gas supply apparatus for supplying the fuel gas to the fuel gas flow field; a scavenging gas supply apparatus for supplying air as a scavenging gas to the fuel gas flow field; and a control device, the scavenging method comprising the steps of:
