摘要： A method for performing a plausibility check of a fuel cell stack anode side pressure sensor to determine whether the pressure sensor is providing an accurate measurement. Prior to system start-up when a cathode side compressor is not providing cathode air to a fuel cell stack, and the cathode side of the stack is at ambient pressure, a pressure measurement from a differential pressure sensor between the anode side and the cathode side of the fuel cell stack is provided. The differential pressure sensor reading is added to a pressure measurement from an ambient pressure sensor, where the sum should be about the same as the pressure measurement from the anode side pressure sensor if the anode side pressure sensor is operating properly.

摘要： A method for quickly and efficiently heating a fuel cell stack at system start-up. The method uses and prioritizes various stack heat sources based on their efficiency to heat the stack. A thermal set-point for heating the stack to the desired temperature is determined based on the ambient temperature and, the stack cooling fluid temperature. The set-point is then compared-to the stack heating provided by the heat sources that are operating through normal system start-up operation. If more heat is necessary to reach the set-point, the method may first charge a system battery using stack power where the load causes the fuel cell stack to heat up. If additional heating is still required, the method may then turn on a cooling fluid heater, then flow a small amount of hydrogen into the cathode inlet stream to provide combustion, and then increase the compressor load as needed.
摘要翻译：一种在系统启动时快速有效地加热燃料电池堆的方法。该方法基于它们的效率来使用并优先考虑各种堆叠热源以加热堆叠。基于环境温度和叠层冷却流体温度来确定用于将叠层加热到所需温度的热定形点。然后将设定点与通过正常系统启动操作操作的热源提供的堆叠加热进行比较。如果需要更多的热量来达到设定点，则该方法可以首先使用负载使燃料电池堆加热的堆叠功率对系统电池充电。如果仍然需要额外的加热，则该方法然后可以打开冷却流体加热器，然后将少量氢气流入阴极入口流以提供燃烧，然后根据需要增加压缩机负载。

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.

摘要： A system and method for quickly heating a fuel cell stack at fuel cell system start-up. The fuel cell system includes a three-way valve positioned in the anode exhaust that selectively directs the anode exhaust gases to the cathode input of the fuel cell stack so that hydrogen in the anode exhaust gas can be used to heat the fuel cell stack. During normal operation when the fuel cell stack is at the desired temperature, the three-way valve in the anode exhaust can be used to bleed nitrogen to the cathode exhaust.

摘要： A system for bleeding the anode side of first and second split fuel cell stacks in a fuel cell system that employs anode flow-shifting, where each split stack includes a bleed valve. The system determines that one or both of the bleed valves is stuck in an open position if there is flow through an orifice and a bleed has not been commanded. A shut-off valve is then used to provide the bleed if the cathode exhaust gas is able to dilute the hydrogen in the bled anode exhaust gas. An outlet valve between the first and second split stacks is used to bleed the anode exhaust gas if the cathode exhaust gas is not significant enough to dilute the hydrogen in the anode exhaust gas. If the first or second bleed valve is stuck in the closed position, then the outlet valve is used to provide the bleed.
