  A simple spin coating approach is introduced to fabricate Yttria-Stabilized
Zirconia (YSZ) electrolyte layer on NiO-YSZ anode substrate for solid oxide
fuel cell applications. Heating the substrate during the slurry spin coating
process enhances the affected area through the layer and leads to optimize the
compacting amount of coated electrolyte particles before sintering procedure.
On top of this bilayer substrate, LCFN is deposited as an intermediate
temperature solid oxide fuel cell cathode, in order to have suitable output
performances at intermediate temperature ranges. Applying humidified hydrogen
as fuel and ambient air as the oxidant, cell performance characterizations
exhibit higher power outputs for prepared sample. Electrochemical Impedance
Spectroscopy measurements on single cells also demonstrate that both
interfacial and Ohmic resistances are reduced. These results along with
Scanning Electron Microscope micrographs reveal that the density of the YSZ
layer which is coated by the suggested approach is better than the usual slurry
spin coating method.
