Nickel-based catalysts are an essential part of internal methane steam reforming in solid oxide fuel cells (SOFCs). Unfortunately, nickel is a very good catalyst not only for methane reforming, but also for methane cracking. Progressive progress on anode-supported SOFCs has been made for the last two decades to discover alternative Ni-based alloys that prevent coking from occurring on the catalysts surface. Sn has been known as one of the prospective anode dopants to reduce the nickel poisoning from carbon formation.
Several observations and modelling calculations from various researchers offer the theory of Sn latch on to the Nickel on the anode surface. The role of Sn-infiltration in the Nicermet anode is observed in this study to give better perspective and understanding towards this approach.
Using commercially available Ni/YSZ-based anode supported half cells, Sn-infiltrated Ni/YSZ SOFCs were manufactured. SnCl2 diluted in ethanol was used to make the dopant solution. Pipette drop technique was used to dope the Sn into anodes due to its simplicity and cost-effectiveness. The characterisation results using SEM-EDX shows that Sn is successfully deposited using this method. Observations point at the possibility that Sn adheres to both NiO and ZrO2 surfaces and whilst it is not affected by the morphology of the surface. Al threads found on the Sn-doped cells after calcination lead to the theory of
impurities sublimation when manufacturing the doped cell. These results will serve as supplementary background data for future developments of Ni-based alloys research.
