Study of Water Gas Shift Reaction over Ceria Based Catalysts in Solid Oxide Fuel Cells

The production of hydrogen with low CO concentration from ethanol steam reforming for use in solid oxide fuel cell has been studied. The performance of tubular SOFC with internal reforming of ethanol in the anode side integrated with water gas shift reaction which is situated at low temperature side of tubular SOFC is studied to compare with a conventional tubular SOFC. The preparation method of Ni supported ceria based catalysts SOFC anode is also taken into consideration. The structural properties, particle size changes and the microstructure of the anodes are investigated using X-ray diffraction and scanning electron microscopy as well as the performance investigation. The Thermogravimetric and SEM analyses are employed to mainly characterize the carbonaceous deposits formed.
