A method for operating a fuel cell system is provided. The method includes controlling the provision of fuel to the fuel cell system operating in a steady-state mode. A 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.
