摘要： A diagnostic system and method identifies fuel injector failure in a fuel cell system including a fuel processor and a fuel source. A fuel injector supplies fuel from the fuel source to the fuel processor. A pressure sensor generates a pressure signal based on pressure between the fuel source and the fuel injector. A fuel injector diagnostic identifies fuel injector failure based on the pressure signal. The fuel injector diagnostic includes a moving window tracker that tracks the pressure signal over a moving window. The fuel injector diagnostic further includes a standard deviation or variance calculator that generates a standard deviation or variance based on the pressure signal in the moving window.

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.

摘要： An air control system (20) and method for a fuel cell system (56) includes a manifold (28), a air delivery device (24) that supplies air to the manifold (28), and a plurality of fuel cell components. A plurality of flow controllers (FCs) (32) control airflow from the manifold (28) to the fuel cell components. A controller (100) communicates with the FCs (32) and the air delivery device (24) and generates a manifold pressure setpoint based on a first factor that is related to fuel cell system (56) stability and a second factor that is a based on minimum and maximum pressures of the air delivery device (24) for a predetermined airflow. If the first and second factors are met, the controller (100) optionally generates the manifold pressure setpoint based on a third factor that is related to fuel cell system (56) efficiency.

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.
