    摘要： A system and method for reducing the frequency of stack stand-by mode events, if necessary, as a fuel cell stack ages and experiences lower performance. The method determines an irreversible voltage loss of the fuel cell stack at predetermined time intervals and determines a stack voltage degradation variable based on the irreversible voltage loss. The method also determines if the stack voltage degradation variable indicates that the fuel cell stack will not meet predetermined stack end-of-life voltage requirements and calculates a maximum allowed voltage degradation rate of the fuel cell stack. The method calculates a maximum number of stand-by mode events per unit time that can be allowed to prevent the stack from exceeding the maximum allowed degradation rate and controls the number of stand-by mode events based on the calculated maximum number of stand-by mode events.

    摘要： A method for purging water from a fuel cell stack at fuel cell system shutdown. The method includes determining a stack water generation request to control the rate of drying of membranes in the stack and determining a cathode catalytic heating water generation request. A maximum charge a battery in the fuel cell system can accept is also determined. An ancillary power request for powering components of the fuel cell system during shutdown is determined. The method allocates how much of the water generation request will be fulfilled by operating the fuel cell stack to charge the battery and to provide the power needed for the ancillary power request, and how much of the water generation request will be fulfilled by cathode catalytic heating that produces water and heat in a cathode side of the fuel cell stack.

    摘要： A system and method for controlling the reactants in anode and cathode compartments of a fuel cell stack while the fuel cell stack is in a stand-by or idle-stop mode. The method includes identifying a voltage set-point for an average voltage of the fuel cells in the fuel cell stack or an overall stack voltage that is a minimum voltage acceptable for the idle-stop mode. The actual cell voltage average or stack voltage is compared to the voltage set-point to generate a voltage error. The voltage error is provided to a controller that does one or both of providing hydrogen gas to the anode compartment of the stack to increase the anode compartment pressure, which decreases the voltage error if the voltage is above the voltage set-point, or providing more cathode air to the cathode compartment of the fuel cell stack if the voltage error is below the voltage set-point.

    摘要： A method for determining if more hydrogen has been added to a fuel cell system than a predetermined threshold amount to detect leaks in an anode subsystem or a cathode subsystem of a fuel cell system. The method includes determining a quantity of hydrogen added to the fuel cell system for a given period of time during a predetermined operating condition of the fuel cell system and determining whether the quantity of hydrogen added is more than the predetermined threshold amount. The method also includes adapting an anode subsystem reactant gas concentration model if the quantity of hydrogen added to the fuel cell system is more than the predetermined threshold amount to provide precise control of pressure in the anode subsystem and the cathode subsystem of the fuel cell system.
