摘要： A fuel cell system that employs a method for determining the potential that a freeze condition will exist after the system is shut-down based on predetermined input, such as ambient temperature, geographical location, user usage profile, date, weather reports, etc. If the system determines that a freeze condition is probable, then the system initiates a purge shut-down of the fuel cell system where water is purged out of the reactant gas flow channels. If the system determines that a freeze condition is unlikely, then it will initiate a normal shut-down procedure without purging the flow channels. The system will then periodically determine if the conditions have changed, and will initiate the purge if a freeze condition subsequently becomes probable.

摘要： A system and method for providing dynamic cathode stoichiometry control in a fuel cell during stack load transients to minimize relative humidity excursions. Particularly, changes in the cathode stoichiometry is controlled as a function of time in response to a decrease or increase in stack current density. Thus, if the stack current density drops to a predetermined current density, the dynamic stoichiometry logic will monitor the low power condition and determine if the condition is sustained, i.e., for an extended period of time. If the low power condition is not sustained, then the cathode stoichiometry does not change, but if it is sustained, then the cathode stoichiometry is increased. The same delay in changing the cathode stoichiometry can be provided for a transition from a low power condition to a high power condition.
摘要翻译：一种用于在堆叠负载瞬变期间在燃料电池中提供动态阴极化学计量控制以最小化相对湿度偏移的系统和方法。特别地，响应于堆叠电流密度的降低或增加，阴极化学计量的变化被控制为时间的函数。因此，如果堆叠电流密度下降到预定的电流密度，则动态化学计量逻辑将监视低功率状态并确定该条件是否持续，即延长的时间段。如果低功率条件不持续，则阴极化学计量不变，但如果持续，则阴极化学计量增加。对于从低功率状态到高功率状态的转变，可以提供改变阴极化学计量的相同延迟。

摘要： A fuel cell monitor connector electrically connects a fuel cell monitor to a fuel cell stack. The fuel cell monitor connector includes a non-conductive housing. First connectors on the housing align with second connectors located on fuel cell plates of the fuel cell stack. A third connector on the housing mates with a fourth connector coupled to the monitor.

When the clamping device is in the locked position, the first connectors retain the second connectors. When the clamping device is in the released position, the first connectors release the second connectors. The clamping device is a zero insertion force connector.

摘要： A method and apparatus for detecting leakage current in the coolant of a fuel cell stack. The invention eliminates the use of a conductivity sensor by using a voltmeter to measure the voltage across the coolant. If the coolant voltage is at or below a predetermined level, an excessive level of conductivity in the coolant exists, and the presence of leakage current is reported. The invention can also compare the coolant voltage to two different predetermined voltage levels, the second one higher than the first. A coolant voltage at or below the lower voltage level could signal a shut down of the stack, while a coolant voltage at or below the higher voltage level could signal an alarm or another diagnostic. The invention can optionally use a second voltmeter to measure the voltage across the stack and calculate the resistivity and conductivity of the coolant.
