摘要： A method for determining whether a fuel cell stack is overheating. The method measures the temperature of end cells in the stack using end cell temperature sensors, and calculates an average end cell temperature based on the end cell temperature measurements. The method also measures the temperature of a cooling fluid being output from the fuel cell stack. The method determines if any of the measured end cell temperatures are outlying by comparing each end cell temperature measurement to the average. The method determines that the cooling fluid outlet temperature sensor has possibly failed if the cooling fluid outlet temperature is greater than the average end cell temperature and the cooling fluid outlet temperature minus the average end cell temperature is greater than a predetermined temperature value.

摘要： A system and method for reducing cathode carbon corrosion during start-up of a fuel cell stack. If a long enough period of time has gone by since the last system shutdown, then both the anode side and the cathode side of the stack will be filled with air. If the system includes split sub-stacks, then a start-up sequence uses a fast hydrogen purge through each sub-stack separately so as to minimize the time of the hydrogen/air front flowing through the anode side of the stacks. The start-up sequence then employs a slow hydrogen purge through the sub-stacks at the same time. If the time from the last shutdown is short enough where a significant amount of hydrogen still exists in the cathode side and the anode side of the sub-stacks, then the fast hydrogen purge can be eliminated, and the start-up sequence proceeds directly to the slow hydrogen purge.

摘要： A fuel cell system that employs a method for increasing stack power ramp up for high power up-transients by decoupling the build-up of stack current density from the cathode side pressure. The system gives the compressor power priority during the power up-transient to quickly provide the proper compressor speed, and therefore the proper air mass flow, for the desired current density of the fuel cell stack. The system also maintains the cathode side pressure of the stack low by keeping a cathode back-pressure valve open. By increasing the cathode input airflow rate to the proper level at the power up-transient, the current density of the stack will increase to the desired stack power level. Subsequently, the back-pressure valve is closed to increase the stack voltage to provide the total maximum power achievable by the stack.
摘要翻译：一种燃料电池系统，其采用通过将堆叠电流密度与阴极侧压力的积聚解耦来增加堆叠功率的方法来提高高功率上变频。该系统在上电瞬态期间给出压缩机功率优先权，以便快速提供适当的压缩机速度，并因此提供适当的空气质量流量，用于燃料电池堆的所需电流密度。该系统还通过保持阴极背压阀打开来保持堆的阴极侧压力低。通过在上电瞬变时将阴极输入气流量增加到适当水平，堆叠的电流密度将增加到所需的堆叠功率水平。随后，背压阀关闭以增加堆叠电压，以提供堆叠可实现的总的最大功率。

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.
