Study on Synthesis of Nano-Crystalline Ba0.5Sr 0.5Co 0.8Fe 0.2O3 Cathode Material by Glycine-Nitrate Combustion Process for Solid Oxide Fuel Cells| Chapter 10 | Newest Updates in Physical Science Research Vol. 15

 Nano ceramics comprising Ba0.5Sr0.5Co0.8Fe0.2O3 (BSCF) powders have been manufactured for solid oxide fuel cells (SOFC) applications utilising a glycine-nitrate combustion process and metal nitrate-based chemicals, as these powders are believed to be more promising cathode materials for SOFC. X-ray diffraction was used to determine the development of crystalline phases in powders after heat treatments at various temperatures (XRD). After thermal treatment of the combustion produced BSCF nanopowders, single phase perovskites were formed. Scanning electron microscopy was used to examine the morphological aspects of powders calcined at various temperatures (SEM). Thermogravimetry (TGA) plots demonstrate that there is no weight loss after 500oC, indicating that combustion is complete. In terms of compositional homogeneity and purity of the end product, combustion synthesis has an advantage over solid state synthesis.
