A recently granted patent (Publication Number: US11876257B2) discloses a method for operating a fuel cell system using a peak shaving fuel. The method involves determining the composition of a fuel stream provided to the fuel cell system and injecting air into the fuel stream if it contains ethane, propane, or a combination of both in concentrations greater than about 9 vol %. The fuel stream is then passed through a reforming catalyst to generate reformed fuel, which is subsequently supplied to a fuel cell stack.

Furthermore, the method includes various additional steps such as adjusting the flow rate of the fuel stream based on temperature and voltage readings from the system. It also involves providing the fuel stream to oxidation and hydrogenation catalysts to catalyze reactions between different components in the fuel stream before supplying it to the reforming catalyst. The patent emphasizes the use of solid oxide fuel cells in the fuel cell stack and the integration of an anode tail gas oxidizer to optimize the operation of the system. Overall, the method outlined in the patent aims to enhance the efficiency and performance of fuel cell systems utilizing peak shaving fuels through a series of carefully orchestrated steps and catalyst interactions.
