  • Publication number: 20150340717
    Abstract: A method and a system are provided for controlling an air intake of a fuel cell vehicle. The method includes calculating a value for basic air intake of a fuel cell based on a driver requirement and calculating a value of motor current requirement based on the driver requirement. A rate-of-change is calculated of the value of motor current requirement and a value for supplementary air intake is calculated by multiplying the rate-of-change of the value of motor current requirement by a gain value. A value for final air intake is then calculated by adding the value for basic air intake and the value for supplementary air intake. An air blower of an air intake system of the fuel cell is operated with the value for final air intake.

  • Patent number: 8859158
    Abstract: The present invention provides a hybrid fuel cell system that is configured to determine if an idle stop condition has been satisfied during a normal operation mode of the hybrid fuel cell system, cut off air supply to a fuel cell to stop power generation of the fuel cell and reduce a voltage which the fuel cell outputs in response to determining that the idle stop condition has been satisfied. The voltage of a bidirectional converter, connected between a battery and a bus terminal is reduced and the output of the fuel cell is controlled, based on a first predetermined value and maintained at that first predetermined value. Subsequently, the battery is charged via the output current of the fuel cell generated by maintaining the reduced voltage of the bidirectional converter.
