摘要:
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.
摘要:
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.
摘要:
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.
