Abstract: Systems and methods are provided for maintaining and/or improving operating lifetime for molten carbonate fuel cells that contain reforming catalyst in the anode when processing cathode input flows that contain sulfur oxides. The systems and methods can include a serial arrangement of molten carbonate fuel cells, where a first fuel cell includes a reduced or minimized amount of reforming catalyst in the anode. A second molten carbonate fuel cell can include reforming catalyst in the anode.
