PROBLEM TO BE SOLVED: To shorten a treatment time for removing a residual moisture by suppressing increase of a power consumption, a structural enlargement and complicated work as much as possible.SOLUTION: When an operation shutdown trigger of a fuel cell system is turned on, the air humidified in a humidifying means 3 is supplied to a fuel cell stack 1 in a lower humidification than during a normal operation; an amount of taking out moisture generated inside the fuel cell stack 1 is increased and power generation of the fuel cell stack 1 is continued for a prescribed time; and then power generation is stopped and a cathode electrode side of the fuel cell stack 1 is purged by the air for a prescribed time. |
