    • A fuel cell system (100) and operational methods (200, 300 and 400) are described that utilize a combination of sensor input and component models for causing the system's cathode effluent (150) to selectively bypass cathode effluent processing components (140) so as to obtain or maintain a desired cathode inlet relative humidity or dew point. The described system and methods may operate open loop (e.g., without sensor feedback to verify operation) or closed loop (e.g., relying on cathode inlet relative humidity/dew point sensors or fuel cell stack membrane conductivity measures).

    • A method is provided for controlling the concentration of nitrogen in a fuel cell stack. The method includes providing a fuel cell stack with cathode passages and anode passages including a valve in communication with the anode passages. The method further comprises selecting a maximum desired amount of nitrogen to be found in the fuel cell stack and calculating an actual amount of nitrogen in the fuel cell stack. Next, the method provides for comparing the maximum desired amount of nitrogen in the fuel cell stack to the actual amount of nitrogen in the fuel cell stack, and opening the valve if the actual amount of nitrogen in the fuel cell stack is greater than the maximum desired amount of nitrogen in the fuel cell stack. The method calculates the actual amount of nitrogen in the fuel cell stack based on an amount of nitrogen that enters the anode passages due to an age of the fuel cell stack.

    • Fuel cell parameters and limited electrochemical fuel cell sensors are used to calculate the concentration of diluting gas on the anode side of the fuel cell. The calculated concentration is then used to optimize fuel cell efficiency and/or stability by controlling the evacuation of diluted fuel from the anode side of the cell. In accordance with one embodiment of the present invention the dilution gas crossover rate of the membrane electrode assembly is calculated and the dilution gas concentration in the anode flow field is determined as a function of the crossover rate. The vent valve is opened when the dilution gas concentration in the anode flow field is above a high threshold value and is closed when the dilution gas concentration in the anode flow field is below a low threshold value.
    • 燃料电池参数和有限的电化学燃料电池传感器用于计算燃料电池阳极侧稀释气体的浓度。 然后计算的浓度通过控制从电池的阳极侧排出稀释燃料来优化燃料电池的效率和/或稳定性。 根据本发明的一个实施例,计算膜电极组件的稀释气体交叉速率,并且确定阳极流场中的稀释气体浓度作为交叉率的函数。 当阳极流场中的稀释气体浓度高于高阈值时,排气阀打开,并且当阳极流场中的稀释气体浓度低于低阈值时关闭。

    • A system and method for putting a fuel cell vehicle into a performance mode by preloading sub-systems in the fuel cell system so that high power is available from the fuel cell stack quicker than during normal fuel cell system operation. For example, if a driver activates a vehicle performance mode, the fuel cell system can respond by, for example, increasing the compressor speed, increasing anode recirculation, increasing air and cooling fluid flow through the radiator, increasing battery state-of-charge, etc. Thus, when the driver requests the high power after the system is in the performance mode, the system is able to deliver the desired power immediately or at least quicker and for a longer time period.

    • A system and method for controlling an anode exhaust gas bleed valve in a fuel cell system that includes estimating the gas composition in the anode exhaust gas, using an inverse valve model to calculate a desired valve flow coefficient, and bleeding the anode exhaust gas at a flow rate that results in the desired valve flow coefficient. The method includes determining the partial pressure of nitrogen in the anode exhaust gas, calculating the partial pressure of water vapor and hydrogen in the anode exhaust gas, and calculating the gas mole fraction of the nitrogen, water vapor and hydrogen in the anode exhaust gas. The method also includes using the gas mole fraction of nitrogen, water vapor and hydrogen to determine the desired valve flow coefficient, and using the desired valve flow coefficient to determine when to open and close the bleed valve.
