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 control system and method for operating a cooling fan in a coolant system of fuel cell power plant having a high temperature coolant loop and a low temperature coolant loop. The fan controller generates a fan control signal based on a first control signal from the high temperature coolant loop and a second control signal from the low temperature coolant loop. The first control signal is a function of the waste heat energy in the high temperature coolant loop, and the second control signal is a function of the temperature in the low temperature coolant loop. The fan control signal may also be generated based on a third control signal which is a function of a localized ambient temperature such as the under hood temperature of a vehicle.

摘要： A method of controlling the operation of a fuel cell system wherein each shutdown command for the system is subjected to decision logic which determines whether the command should be a normal shutdown command or rapid shutdown command. If the logic determines that the shutdown command should be a normal shutdown command, then the system is shutdown in a normal step-by-step process in which the hydrogen stream is consumed within the system. If the logic determines that the shutdown command should be a rapid shutdown command, the hydrogen stream is removed from the system either by dumping to atmosphere or routing to storage.

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 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.
