Abstract
First, a reaction gas is supplied to a fuel cell stack including a laminate of solid polymer electrolyte fuel cells and power generation is performed so that a temperature of the fuel cell stack reaches 65° C. or higher (heating power generation step). Next, the reaction gas is supplied to the fuel cell stack and the power generation is performed under a condition in which relative humidity is 100% or more (cleaning power generation step). Cooling water of room temperature may be supplied to the fuel cell stack from the outside before the cleaning power generation step is performed after the heating power generation step is completed, or after the cleaning power generation step is completed (quenching step).
