摘要： A system and method for controlling a fuel cell system. An anode tail gas oxidizer (ATO) receives air and fuel exhaust streams from one or more fuel cell stacks of the fuel cell system. The one or more fuel cell stacks provide current to one or more loads. An ATO temperature signal is used to control at least one of a fuel inlet flow to the one or more fuel cell stacks or the current provided to the one or more loads.

摘要： A method for operating a fuel cell system is provided. The method includes controlling a provision of fuel to the fuel cell system operating in a steady-state mode. The catalyst sensor is operated by providing a portion of the fuel and anode exhaust generated by the system to the catalyst sensor. Further, a change in an outlet temperature of the catalyst sensor is detected. Thereafter, it is determined whether a reformation catalyst of the catalyst sensor is poisoned by contaminants in the fuel based on the detected change in the outlet temperature.
