摘要： PROBLEM TO BE SOLVED: To reduce time required for forming an interface between hydrogen gas and air in an anode at starting of a fuel cell system and suppress deterioration of the fuel cell.
SOLUTION: At starting of the fuel cell system, a cut-off valve 10 provided in a hydrogen gas circulation passage 9 is closed and a purge valve 11 is opened, whereby a gas remaining in an anode 4 is scavenged by a gas circulation device 8, and the pressure of the anode 4 is controlled at a negative pressure (pressure lower than atmospheric pressure). A target value of the negative pressure may be changed according to temperature, oxygen concentration (or hydrogen concentration), and the time passed since the previous stop of the fuel cell. After the anode pressure is made at the negative pressure, a pressure control valve 6 and the cut-off valve 10 are opened and the purge valve 11 is closed, and hydrogen gas is supplied to the anode 4 and the fuel gas circulation is started.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of reducing an uncomfortable feeling of a system user and expecting fuel economy enhancing effect.
SOLUTION: A system control device 130 stops power generation by a fuel cell 10 after satisfying the prescribed conditions, and when the power generation by the fuel cell is restarted, even if the prescribed conditions are satisfied in idle stop inhibit time after restarting of power generation, the system control device 130 does not stop power generation by the fuel cell 10. During the idle stop inhibit time, since the system do not become an idle stop state, the system can prevent the system user from being given an uncomfortable feeling by repetition of usual operation and idle stop. The system control device 130 exhausts gas through a gas exhausting line 40 during the idle stop inhibit time. Therefore, nitrogen concentration is decreased, and even in a fuel cell system releasing the idle stop state when the nitrogen concentration reaches a prescribed value, the idle stop state is not immediately released.
