In Situ Tailored Nickel Nano-Catalyst Layer for Internal Reforming Hydrocarbon Fueled SOFCs
In this work, non-stoichiometry perovskite (La0.8Ce0.1Ni0.4Ti0.6O3) as reforming layer can lead to Ni nano particle exsolution with homogenous distribution and high population in reduction atmosphere. This catalyst layer was applied on Ni-GDC anode supported single cell to prevent carbon deposition through reforming hydrocarbon fuel at outer surface.
The catalyst layer showed excellent attachment with Ni-GDC anode and resistance of carbon deposition. The performance of Ni–GDC anode-supported single cells with catalyst layer was about 1 W/cm2 in hydrogen fuel as similar as without catalyst layer. We are also analyzing of cell performance in dry methane and partial oxidation of methane to clarify the presence of nano nickel particles in the catalyst layer and its effect on the electrode-catalytic activity and polarization resistance.
