Abstract: A fuel cell system and method for using a peak shaving gas, the system including: a fuel inlet configured to receive fuel from a fuel source; a catalytic partial oxidation (CPOx) reactor configured to at least partially oxidize the fuel during startup of the system; a blower configured to provide air to the CPOx reactor; a gas analyzer configured to determine a composition of fuel provided to the CPOx reactor from the fuel inlet; an oxidation catalyst configured to reduce an O2 content of fuel received from the CPOx reactor; a reforming catalyst configured to partially reform fuel received from the oxidation catalyst; and a stack of fuel cells configured to generate electricity using fuel received from the reforming catalyst.

Abstract: 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.
