摘要： In an improved method, the voltage of one or more cells in a fuel cell stack is monitored. The monitored voltage is compared to first and second preselected voltage values as a function of load, where the second preselected value is less than the first preselected value. Next, either a first signal is generated if the monitored voltage is less than the first preselected voltage value and greater than or equal to the second preselected voltage value; or a second signal is generated if the monitored voltage is less than the second preselected voltage value.

摘要： A venting methodology and system for rapid shutdown of a fuel cell apparatus of the type used in a vehicle propulsion system. H2 and air flows to the fuel cell stack are slowly bypassed to the combustor upon receipt of a rapid shutdown command. The bypass occurs over a period of time (for example one to five seconds) using conveniently-sized bypass valves. Upon receipt of the rapid shutdown command, the anode inlet of the fuel cell stack is instantaneously vented to a remote vent to remove all H2 from the stack. Airflow to the cathode inlet of the fuel cell stack gradually diminishes over the bypass period, and when the airflow bypass is complete the cathode inlet is also instantaneously vented to a remote vent to eliminate pressure differentials across the stack.

摘要： A control method for monitoring a fuel cell stack in a fuel cell system in which the actual voltage and actual current from the fuel cell stack are monitored. A preestablished relationship between voltage and current over the operating range of the fuel cell is established. A variance value between the actual measured voltage and the expected voltage magnitude for a given actual measured current is calculated and compared with a predetermined allowable variance. An output is generated if the calculated variance value exceeds the predetermined variance. The predetermined voltage-current for the fuel cell is symbolized as a polarization curve at given operating conditions of the fuel cell.

摘要： A venting methodology and pressure sensing and vent valving arrangement for monitoring anode bypass valve operating during the normal shutdown of a fuel cell apparatus of the type used in vehicle propulsion systems. During a normal shutdown routine, the pressure differential between the anode inlet and anode outlet is monitored in real time in a period corresponding to the normal closing speed of the anode bypass valve and the pressure differential at the end of the closing cycle of the anode bypass valve is compared to the pressure differential at the beginning of the closing cycle. If the difference in pressure differential at the beginning and end of the anode bypass closing cycle indicates that the anode bypass valve has not properly closed, a system controller switches from a normal shutdown mode to a rapid shutdown mode in which the anode inlet is instantaneously vented by rapid vents.

摘要： A control system controls steam in a fuel cell system including a fuel processor. A fuel cell has run, standby and shutdown operating modes. A fuel processor provides reformate to the fuel cell. A pressure sensor generates a pressure signal based on a pressure of steam supplied to the fuel processor. A valve directs steam to or vents steam away from the fuel processor. A controller communicates with the pressure sensor, the fuel cell and the valve and controls the valve based on the operating mode of the fuel cell and the pressure signal. The controller opens the valve during the shutdown mode. The controller closes the valve during the run operating mode. The controller initially closes the valve during the standby mode. The controller opens the valve if the pressure signal exceeds a first predetermined pressure value and closes the valve when the pressure falls.

摘要： A system and method for controlling hydrogen gas flow to an anode side of a fuel cell stack using a pressure regulator in the event that an injector that normally injects the hydrogen gas into the fuel cell stack has failed in a stuck open position. During normal operation, the control of the injector is determined based on the pressure of an anode sub-system and the position of the pressure regulator is determined based on a supply pressure between the pressure regulator and the injector. If it is determined that the injector is stuck in an open position, then the position of the pressure regulator is controlled to the anode pressure instead of the supply pressure. If the pressure regulator is an electrical pressure regulator, then it is pulsed to mimic normal system operation. Alternately, another valve, such as a shut-off valve, can be employed to provide the flow pulsing.
