In this paper, we will present that various metals mixed with ceria are good sulphur tolerant shift reaction catalysts. Without adding the shift catalyst to Ni-based anode, although stable fuel cell performance is achieved in carbon monoxide fuels, fuel cell experiences catastrophic degradation when adding 1 ppm hydrogen sulphide. While the nickel-based anode will still be poisoned by 1 ppm hydrogen...
In this paper solid oxide fuel cells operating with dry synthetic biogas have been examined. In order to increase their stability the layers of CuO-CeO 2 , Cu 1.3 Mn 1.7 O 4 and Y 0.08 Sr 0.92 Ti 0.8 Fe 0.2 O 3-δ have been deposited on the Ni-YSZ anode site. These layers should catalyze the internal biogas reforming and prevent...
