摘要： 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).

摘要： A water electrolysis device is configured to obtain hydrogen and oxygen by performing electrolysis of water with a plurality of water electrolysis cells. The water electrolysis device includes a water electrolysis stack that includes the water electrolysis cells, a water supply side passage including first piping through which water supplied to the water electrolysis stack flows, and second piping, a hydrogen side passage through which hydrogen generated in the water electrolysis stack flows, a gas-liquid separator that is provided in the water supply side passage and that is configured to perform gas-liquid separation of a fluid containing oxygen and water discharged from the water electrolysis stack, and a hydrogen combustion member that contains a hydrogen combustion catalyst and that is disposed on an inner side of the second piping. The second piping connects the water electrolysis stack and the gas-liquid separator.
