摘要： When it is detected that the ignition switch is turned off a short period of time after the ignition switch turned on at the temperature below the freezing point, the charge threshold of a capacitor is changed to a larger charge threshold C for increasing the amount of electrical energy charged in the capacitor based on the charge threshold C. The capacitor is used for performing a scavenging process for a sufficient period of time. At the time of starting operation of the fuel cell system at the temperature below the freezing point the next time, using the electrical energy of the capacitor, a fuel cell is warmed rapidly by a heater or the like to start operation of the fuel cell system.

摘要： A fuel cell system includes a fuel cell, a fuel gas supply channel, a fuel off-gas discharge channel, an oxidant gas supply channel, an oxidant off-gas discharge channel, a first shut valve, a second shut valve, a shut valve controller, a temperature detector, a scavenging device, and an elapsed-time detector. The elapsed-time detector is configured to detect an elapsed time elapsed from a timing at which the fuel cell is shut down. The scavenging device scavenges the oxidant gas flow channel and the fuel gas flow channel in sequence if the elapsed time detected by the elapsed-time detector is within a first predetermined period of time. The scavenging device scavenges the fuel gas flow channel and the oxidant gas flow channel in sequence if the elapsed time detected by the elapsed-time detector is outside the first predetermined period of time.

摘要： A fuel cell system comprises a fuel cell stack, a cell voltage monitor, a hydrogen tank, a hydrogen supply channel, an ejector, a hydrogen off-gas channel, a purge valve, a compressor, an air supply channel, a pressure control unit for controlling air pressure, a pilot pressure input channel branching off from the air supply channel and inputting the air pressure to the ejector as pilot pressure, and a control unit for controlling the purge valve and the pressure control unit. The ejector includes a pressure control mechanism which increases the ejector's secondary-side pressure by increasing the area of the nozzle's ejecting hole when the pilot pressure input from the pilot pressure input channel rises. When electricity generation status of the fuel cell stack is judged to be poor, the control unit opens the purge valve after raising the air pressure and the pilot pressure by using the pressure control unit.
