Abstract
In this research work, we report the synthesis and characterization of NiO-Ce0.95Nd0.05O2-δ-Ce0.95Gd0.05O2-δ (NiO-CNO-CGO) nanocomposite anode material for LTSOFC. The thermal properties of NiO-CNO-CGO precursor were studied using TGA-DSC analysis which inferred that the formation of pure-phase was completed at around 600 °C. XRD analysis reveals a single fluorite cubic phase structure. FTIR data confirmed the occurrence of stretching vibration of M-O bond in the sample. Presence of nano-sized particles was confirmed by particle size analysis. The surface morphology was studied using SEM resulting in unsmooth grains. Respective atomic weight percentage of Ni, Ce, Nd, Gd and O was confirmed by EDAX studies. The surface roughness was studied using AFM. The sample resulted in a conductance of 4.55 x 10−4 Scm−1 in air atmosphere with activation energy of 0.4483 eV. The obtained results were discussed in order to use the material as an efficient anode for LTSOFC application.
