摘要： A remedial method for starting a fuel cell system is described. The method includes determining if the remedial method is required; providing air to an exhaust of a fuel cell stack; setting a hydrogen flow rate to an anode side of the fuel cell stack; providing a predetermined volume of hydrogen to the anode side of the fuel cell at the hydrogen flow rate; providing a predetermined volume of air to a cathode side of the fuel cell stack after the predetermined volume of hydrogen has been provided to the anode side while continuing to provide air to the exhaust of the fuel cell stack and hydrogen to the anode side of the fuel cell stack; determining if a stack voltage is stable after the predetermined volume of air has been provided to the cathode side; and closing the anode outlet valve after the stack voltage is stable.

摘要： A system and method for determining a loss of cooling fluid from a thermal sub-system in a fuel cell system. The method includes monitoring current feedback from a high temperature pump that pumps the cooling fluid through a coolant loop. A measured current from the pump is compared to an expected current for the system operating conditions, and if that current is significantly less than what is expected, then it may be as a result of low cooling fluid. If the measured current is less than the expected current for a predetermined period of time, then the system can take mitigating action as a result of a low cooling fluid. Further, if the pump speed is too low to provide an accurate current measurement, then it can be increased if an overflow tank level sensor indicates a low cooling fluid level.

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 fuel cell system that employs an algorithm for limiting the current output from a fuel cell stack using feedback during high stack temperature operation. The system includes a PID controller that receives an error signal that is the difference between the cooling fluid output temperature from the stack and a predetermined temperature value. The algorithm detects whether the cooling fluid output temperature goes above a predetermined temperature value, and if so, calculates a proportional gain component and an integral gain component that sets the proportional and integral gains of the PID controller. Based on the proportional gain component, the integral gain component and the error signal, the algorithm generates a total current allowed, and sets the maximum current draw from the stack accordingly. The rate of the rise or fall of the allowed current from the stack from the actual current is limited to provide a smooth transition.
