摘要：PROBLEM TO BE SOLVED: To provide a gas purging method for a fuel cellcapable of quickly discharging fuel gas and hydrogen ions remaining in the fuel cell. A gaspurging method for a fuel cell according to the present invention includes a fuel gas flowpath in a state where supply of an oxidizing gas to an oxidizing gas flow path (21A) and

supply of a fuel gas to a fuel gas flow path (21B) are stopped. A differential pressure isapplied so that the pressure of the inert gas in (21B) is higher than the pressure of theinert gas in the oxidizing gas passage (21A), and the oxidizing gas passage (21A) and thefuel gas passage (21B) ), the step of supplying an inert gas into at least the fuel gas flowchannel (21B) is included.
