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 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.

摘要： A system and method for putting a fuel cell vehicle system into a stand-by mode where there is little or no power being consumed, the quantity of fuel being used is minimal and the fuel cell system is able to quickly recover from the mode. The method includes determining whether predetermined stand-by mode vehicle level entrance criteria have been satisfied at a vehicle control level and predetermined stand-by mode fuel cell level entrance criteria have been satisfied for a fuel cell system control level, and putting the vehicle in the stand-by mode if both the vehicle level entrance criteria and the fuel cell level entrance criteria have been satisfied. The method exits the stand-by mode if predetermined vehicle level exit criteria have been satisfied or predetermined fuel cell level exit criteria have been satisfied.

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 method for improving fuel cell system reliability in the event of end cell heater failure in a fuel cell stack. The method includes detecting that an end cell heater has failed. If an end cell heater failure is detected, then the method performs one or more of setting a cooling fluid pump to a predetermined speed that drives a cooling fluid through cooling fluid flow channels in the fuel cell stack, limiting the output power of the fuel cell stack or the net power of the fuel cell system, limiting the maximum temperature of the cooling fluid flowing out of the stack, turning off stack anti-flooding algorithms that may be used to remove water from reactant gas flow channels in the stack, and turning off cathode stoichiometry adjustments for relative humidity control in response to water accumulating in cathode flow channels in the fuel cell stack.
