To provide an operating method whereby wet reaction air can be supplied to a fuel cell stack when restarting the polymer electrolyte fuel cell generating device, and an air passage is not blocked, in an operating method of the polymer electrolyte fuel cell generating set using a humidifier to humidify reaction air by using off-air.
In this operating method of the polymer electrolyte fuel cell generating device provided with a humidifier 2 to humidify reaction air introduced into the fuel cell stack 1 by using moisture in off-air derived from the fuel cell stack 1 through a flat diaphragm 4, opening and closing valves (3 and 5) are provided between the humidifier 2 and the fuel cell stack 1 on a reaction air introducing line and at the outlet of the humidifier on the off-air deriving line, and when stopping operation of the fuel cell generating device, the two opening and closing valves are closed.
