摘要： PROBLEM TO BE SOLVED: To purge rapidly without using a gas for exclusive use for purging. SOLUTION: When a reformer 30 and a fuel cell 40 are purged at the stopping of the system, a control valve 38 is closed and supply of steam to the city gas as a reforming material supplied to the reformer 30 is stopped, and a control valve 47 is closed, and by opening a control valve 48, the gas pushed from the fuel cell 40 by the city gas is introduced into the combustor 48 and burned and exhausted. And after waiting the completion of purging of the reformer 30, a CO selective oxidation part 34, and the fuel cell 40, the control valve 28 is closed and the control valve 48 is opened, and the purge process is completed. Since the reformer 30 and the fuel cell 40 are purged using the city gas which is used for reforming material as a purging gas, it is not necessary to prepare a gas for exclusive use for purging. And since it is not necessary to carry out temperature control and moisture control to the city gas when used as a purging gas, rapid purging can be made. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an advantageous fuel cell system for securing an appropriate humidification state of the inside of the fuel cell. SOLUTION: A humidification part 20 has a humidification member 20n capable of absorbing moisture. The humidification member 20n is humidified by an off-gas of a reactant gas after power generation discharged from a fuel cell 8, and the reactant gas prior to the power generation going to the fuel cell 8 is humidified at the humidification member 20n. This system has a humidification state detecting means of the fuel cell to detect the humidification state of the inside of the fuel cell 8 based on a dimensional change in the lamination direction or a load change in the lamination direction of the fuel cell 8. In accordance with the humidification state of the fuel cell, the amount of the off-gas of the reactant gas after the power generation going to a by-path passageway 202 without passing through the humidification part 20 from the fuel cell 8 is made variable. Therefore, the amount of the off-gas of the reactant gas after the power generation going to the humidification part 20 is made variable. Because of this, moisture content in the humidification member 20n is made variable, and the humidified state of the reactant gas prior to the power generation supplied to the fuel cell 8 is controlled.
