摘要： A valve for a fuel cell system includes a valve housing having a valve seat formed therein. The valve seat includes an orifice formed therein to permit a fluid to flow through the valve housing. A movable member is disposed in the valve housing and is movable between an open position and a closed position. The movable member includes a first end having an elongate portion and a generally conical shaped base. At least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position to militate against a formation of ice across the orifice of the valve seat.

摘要： A valve for a fuel cell system includes a main body having a passage through which a fluid is permitted to flow. A sliding member is disposed in the main body and configured to move between an open position and a closed position. The sliding member has an orifice formed therein. At least one biased plug is disposed within the main body adjacent the sliding member. The biased plug abuts an outer surface of the sliding member and permits fluid flow through the orifice of the sliding member when the sliding member is in the open position. The biased plug seals the orifice of the sliding member and militates against a formation of ice in the orifice when the sliding member is in the closed position.

摘要： A method for providing an accurate time that a fuel cell system has been shut-down so that the gas constituents in the anode and cathode side of the fuel cell stack can be known for an efficient next system start-up sequence. The method uses two timers, a stand-by timer that provides a time count for how long the fuel cell system has been off, but the vehicle ignition is still on, and a shut-off timer that provides a time count of how long the vehicle ignition has been off. The two time counts are added to give a complete time count of how long the fuel cell stack has been shut-down.

摘要： A system and method for improving fuel cell system start-up reliability. The method includes determining if the resistance of the membranes in a fuel cell stack is too high, where the reliability of system start-up will be reduced, and if so, providing one or more remedial actions to help ensure that the start-up is more reliable. In one embodiment, the system and method determine that the fuel cell membranes are to dry based on whether a high frequency measurement of the fuel cell stack exceeds a predetermined HFR threshold. If the HFR threshold has been exceeded, a special start-up procedure is used that increases the reliability that the start-up will be successful using the remedial actions, such as reducing cathode airflow and turning on stack end cell heaters.

摘要： A method for providing a fast and reliable start-up of a fuel cell system. The method uses a stack voltage response to a load to assess if hydrogen and oxygen are being sufficiently distributed to all of the fuel cells by coupling an auxiliary load to the fuel cell stack until a predetermined minimum cell voltage has been reached or a first predetermined time period has elapsed. The method then determines whether a minimum cell voltage has dropped to a first predetermined voltage and, if so, reduces the maximum power allowed to be below the first predetermined voltage value, determines whether the minimum cell voltage in the stack is below a second predetermined voltage, or determines whether the minimum cell voltage drop rate is greater than a predetermined voltage drop rate. If none of these conditions are met, the method returns to loading the stack with system components.

摘要： A system and method for monitoring anode bleed trigger events and determining when to adjust a proactive bleed schedule in a fuel cell system. The system employs a bleed trigger monitor algorithm for monitoring proactive bleed and reactive bleeds that determines whether the reactive bleeds are caused by excess nitrogen in the anode. The algorithm monitors the number of reactive bleeds that are cause by nitrogen accumulation in the anode side of the fuel cell stack and changes the proactive bleed schedule in response thereto, if necessary.
