    摘要： A hybrid fuel cell system that employs a fuel cell stack and an ultracapacitor. A diode is provided on a high voltage electrical bus between the fuel cell stack and the ultracapacitor so that high voltage from the ultracapacitor does not affect the operation of the fuel cell stack. During system start-up, a by-pass switch is closed to by-pass the ultracapacitor so that power from the ultracapacitor can be used to start various system loads, such as a cathode side air compressor that provides air to the fuel cell stack. A 12 volt-to-high voltage converter is employed to provide a low power, high voltage supply from a low voltage battery to the system loads at start-up when the by-pass switch is opened, but before a fuel cell stack switch is closed.

    摘要： A gas flow control system for a fuel cell includes a gas supply and a humidifier. A fuel cell stack includes a cathode flow line with an inlet and an outlet. The inlet of the cathode flow line is connected to the outlet of the humidifier. A combustor includes an inlet that receives gas from the outlet of the cathode flow line. A valve and a bypass line bypass gas around the humidifier and the fuel cell stack to the combustor. The valve is preferably one of a gas restriction valve, a throttle valve, and a directional valve. A gas flow sensor generates a gas flow signal based on gas flowing through at least one of the humidifier, the cathode flow line of the fuel cell stack, and the bypass line. A flow controller that is connected to the gas flow sensor and the valve controls the valve based on the gas flow signal.

    摘要： A fuel cell system is provided that includes a fuel cell stack with a plurality of fuel cells and a power converter in electrical communication with the fuel cell stack. The power converter is configured to selectively regulate a power of the fuel cell stack and short circuit the fuel cell stack, as desired. A method for starting the fuel cell stack is also described, including the steps of causing a short circuit of the fuel cell stack by placing the power converter in a short circuit mode; introducing a hydrogen to the anodes of the fuel cell stack to displace a quantity of air on the anodes; and placing the power converter in a power regulation mode. A degradation of the fuel cell stack during start-up is thereby militated against.
