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 (20). A fuel cell (40) has run, standby and shutdown operating modes. A fuel processor (20) provides reformate to the fuel cell(40). A pressure sensor (54) generates a pressure signal based on a pressure of steam supplied to the fuel processor(20). A valve (56) directs steam to or vents steam away from the fuel processor (20). A controller (60) communicates with the pressure sensor (54), the fuel cell (40) and the valve (56) and controls the valve (54) based on the operating mode of the fuel cell (40) and the pressure signal. The controller (60) opens the valve (54) during the shutdown mode. The controller (60) closes the valve (56) during the run operating mode. The controller (60) initially closes the valve (56) during the standby mode. The controller (60) opens the valve (56) if the pressure signal exceeds a first predetermined pressure value and closes the valve (56) when the pressure falls.

IPC分类号： H01M8/04
摘要： Hydrogen in a fuel cell (122) is vented and purged with a fail-closed valve (172) using stored energy (e.g. from a capacitor) when a diagnostic parameter is outside of an acceptable operating range. The valve closes after the stored energy has depleted. A safety switch in the relay circuit of the solenoid switch (or solenoid valve) is also grounded in shutdowns implemented by a computer (164). Benefits from the invention include use of air-compatible catalysts, minimized parasitic losses to power output, minimized contamination of fuel cell internal surfaces after venting, minimized risk of explosive mixture buildup, and efficient operation.

摘要： A sensor (116) for monitoring the lambda of a component of a reactant feed stream (86) flowing through a fuel cell stack (32). The sensor (116) comprises one or more fuel cells (94) that are sensitive to a change in lambda of a specific component of a reactant feed stream (86) flowing through the fuel cell (94). The sensitivity of the fuel cell (94) causes a voltage produced by the lambda of the specific component. The variation of the voltage output can be modeled and/or compared to empirical data to correlate the voltage output to the lambda of the specific component. Based on the lambda of the specific component, the operation of the fuel cell stack (32) can be optimized.

摘要： A control system and method for operating a cooling fan (34) in a coolant system of a fuel cell power plant having a high temperature coolant loop (10). The fan controller (30) generates a fan control signal based on a first control signal from the high temperature coolant loop (10) and a second control signal from the low temperature coolant loop (12). The first control signal is a function of the waste heat energy in the high temperature coolant loop (10), and the second control signal is a function of the temperature in the low temperature coolant loop (12). 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. The control system allows operation of a single coolant fan assembly (34) based on a plurality of independent control signals associated with various coolant subsystems in the fuel cell power plant.
