Abstract: A distributed fault management system includes at least one sensor associated with a fuel cell system and at least one first fault management computing device coupled to the at least one sensor. The at least one first fault management computing device is configured to receive data associated with a first fault condition. The at least one first fault management computing device is further configured to generate a resolution to the first fault condition and transmit at least one resolution command signal to at least one second fault management computing device. The at least one resolution command signal configures the at least one second fault management computing device to use the resolution to resolve a second fault condition in a similar manner.

Abstract: A power system includes a first power asset include a first power source and a first power controller. The first power controller includes a first filter configured to receive an error amount at a first frequency range and a second power controller includes a second filter configured to receive the error amount at a second frequency range. The first power controller is configured to instruct the first power source to produce a first amount of power, adjust the first amount of power based on the error amount received by the first filter until the error amount received is substantially zero. When the error amount received is substantially zero, the first power controller is configured to determine a first desired operating amount of power based on the first power source, and adjust the first amount of power based on the first desired operating amount of power.

Abstract: A technique that is usable with a fuel cell system having a fuel cell stack includes storing in a memory a healthy behavior pattern and an unhealthy behavior pattern for the fuel cell stack, comparing observed behavior of the fuel cell stack to the healthy and unhealthy behavior patterns, and classifying the observed behavior as healthy or unhealthy based on the comparison. The technique further includes modifying the stored healthy behavior pattern and the stored unhealthy behavior pattern based upon the occurrence of a predetermined event, such as the detection of an unhealthy condition, the issuance of an alarm, or the passage of a time interval. Modifying the behavior patterns enhances the accuracy of the health classification since the modification takes into account actual system behavior and any performance degradation that may occur over time.

Abstract: In a fuel cell system, a reactor oxidizes excess fuel from an exhaust of a fuel cell. Based on at least fuel flow to the reactor and a temperature associated with the reactor, a change to be made to the oxidant flow to the reactor is determined. A setting of at least one oxidant flow control element is adjusted in response to the determined change.

Abstract: A technique includes controlling the formation of coke during a startup phase of a reformer. The controlling includes during the startup phase regulating a hydrocarbon flow rate into the reformer to be near or below a lower boundary of a range of rates over which the hydrocarbon flow rate varies after the startup phase.

Abstract: Input parameters regarding operation of a fuel cell system are received, where the input parameters include, as examples, a setting of a valve, a setting of a blower, and a temperature in a reformer. The input parameters are applied to a model. Based on applying the input parameters to the model, an indication regarding source fuel flow in the fuel cell system is produced.

Abstract: A technique that is usable with a fuel cell system includes using the fuel cell system to provide power to a load. The technique includes providing a model that indicates a future power demand from the load and regulating an operation of the fuel cell system in response to the future power demand that is indicated by the model.
