    摘要： A system and method for limiting the amount of hydrogen being bled from an anode exhaust line. The method includes maintaining a pressure bias between an anode outlet and a cathode outlet of a fuel cell stack so that when an anode exhaust gas is bled from the anode exhaust line and mixed with the cathode exhaust gas, the concentration of hydrogen in the mixed gas is maintained below a predetermined percentage. The pressure bias is such that the anode exhaust gas has a higher gas pressure than the cathode exhaust gas.

    摘要： A fuel cell system that employs a technique for nitrogen bleeding. The fuel cell system includes a fuel cell stack having a first sub-stack and a second sub-stack, where the hydrogen gas flow is flow-shifted between the sub-stacks. A first nitrogen bleed valve is provided in an anode gas input line coupled to the first sub-stack and a second nitrogen bleed valve is provided in an anode gas input line coupled to the second sub-stack. When the first sub-stack is receiving the anode gas, and a nitrogen bleed is requested, the first bleed valve is closed and the second bleed valve is opened to provide the nitrogen bleeding. When the second sub-stack is receiving the anode gas, and a nitrogen bleed is requested, the second bleed valve is closed and the first bleed valve is opened to provide the nitrogen bleed.

    摘要： A method for triggering an anode bleed from split fuel cell stacks in a fuel cell system that employs anode flow-shifting. The method requests the bleed if any one of three different conditions are met. Those conditions include that the concentration of nitrogen in the anode side of the split stacks is above a predetermined percentage, the voltage spread between the maximum cell voltage and the minimum cell voltage of two fuel cells in the split stacks is greater than a predetermined spread voltage and the absolute value of the difference between the overall voltage of the two split stacks is greater than a predetermined voltage. The concentration of nitrogen in the anode can be determined in any suitable manner, such as by a nitrogen cross-over model or a sensor.

    摘要： A fuel cell system that increases stack stability by reducing the amount of liquid water droplets at the anode input of a fuel cell stack in the system. Re-circulated anode exhaust gas from the fuel cell stack and fresh hydrogen gas are sent to an anode heat exchanger so that both the fresh hydrogen gas and the re-circulated anode exhaust gas are heated to reduce the formation of water droplets in the anode input gas. Further, a portion of the heated cooling fluid directly from the fuel cell stack is sent to the heat exchanger to heat the fresh hydrogen gas and the re-circulation hydrogen before the cooling fluid is sent to an isolation heat exchanger to have its temperature reduced.
