    摘要： A temperature control system and method controls temperatures of front and back ends of a shift reactor. Front and back end temperature sensors sense temperatures of the front and back ends of the shift reactor and generate front and back end temperature signals. An actuator injects fluid into the front end of the shift reactor. A controller communicates with the front end temperature sensor, the back end temperature sensor and the actuator and controls the temperature of the front end and the back end. The controller includes primary and secondary control loops. The secondary control loop communicates with the back end temperature sensor. The primary control loop communicates with the front end temperature sensor. The secondary control loop generates a temperature setpoint for the primary control loop. The secondary control loop has a slower response time that the primary control loop.

    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 method for delaying an air purge of a fuel cell stack at system shut-down until the temperature of the stack is reduced below a predetermined temperature. The fuel cell stack includes an anode side, a cathode side, an anode input, a cathode input and an anode exhaust. A temperature sensor monitors the temperature of a cooling fluid flowing through the stack. The anode side of the fuel cell stack is purged at the stack shut-down by directing air from the cathode input line to the anode input line after the temperature of the cooling fluid is reduced to the predetermined temperature.
