Lattice Expansion and Crystallite Size Analyses of NiO-BaCe0.54Zr0.36Y0.1O3-δ Anode Composite for Proton Ceramic Fuel Cells Application

This study reports on the structure analyses of NiO-BCZY (BCZY = BaCe0.54Zr0.36Y0.1O3-δ) anode composite materials with ratio 50:50 for proton ceramic fuel cells (PCFCs) application. A product sintered was developed to understand structural properties materials. The objectives this work were (a) investigate lattice expansion by using a high-temperature XRD (HT-XRD) from 400–700 °C; and (b) calculate crystallite size sample Scherrer’s Williamson Hall’s methods. results obtained HT-XRD revealed that diffraction peaks NiO BCZY are matched cubic phase perovskite structure. For example at T 400 °C, parameter is 4.2004 Å 4.3331 Å. observation also showed increased temperature. Furthermore, Scherrer Hall methods, respectively, strongly correlated expansion, which proved as operating temperature increased. increment over contributed conductivity values single cell.
