摘要： PROBLEM TO BE SOLVED: To solve the problem of the conventional fuel cell systems in which a cathode catalyst deteriorates during suspension of a power-generating operation if it is not properly determined whether or not to suspend a power-generating operation of a fuel cell.SOLUTION: In a fuel cell system, a control valve is periodically opened and closed so as to periodically increase and decrease pressure of anode gas downstream of the control valve. A power-generating operation of a fuel cell is suspended in response to a power-generation suspension command given to the fuel cell. When a predetermined condition for the resumption of operation is satisfied, the power-generating operation of the fuel cell, along with supply of anode gas to the fuel cell, is resumed. Anode gas concentration in a position in a power-generating region of the fuel cell where the anode gas concentration becomes locally low is determined. According to the anode gas concentration as determined, it is determined whether or not to shift to a process of suspending a power-generating operation of the fuel cell.

摘要： PROBLEM TO BE SOLVED: To effectively restrain performance degradation of a fuel cell, and shorten time needed for operation stoppage of a system. SOLUTION: While oxygen remaining at a cathode 1b side is fully consumed by current extraction from a fuel cell stack 1 by a current extraction part 31, an air system inlet valve 23 and an air system outlet valve 24 are closed to restrain ingress of outer air into a regulated zone. Here, closing of the air system inlet valve 23 and the air system outlet valve 24 is to be carried out after an anode pressure is boosted above atmospheric pressure and higher than a cathode pressure. With this, oxygen consumption speed at a cathode 1b side can be heightened without adversely affecting an electrolyte film of the fuel cell stack 1, so that time needed for stoppage of the system can be shortened.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system that efficiently discharges inert gas while suppressing fuel-gas discharge.
SOLUTION: A purge valve 14 is opened in response to a hydrogen pressure increasing process in a fuel electrode of a fuel cell stack 1. By this, if high-hydrogen-concentration gas is introduced in response to the pressure increase, low-hydrogen-concentration gas remaining in the fuel electrode is pushed out to a volumetric capacity part 12 so as to be replaced with the high-hydrogen-concentration gas. The low-hydrogen-concentration gas pushed out to the volumetric capacity part 12 is discharged from the purge valve 14.
