Studies on Batio3 Anode Material for Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFC)
J. Environ. Nanotechnol., Volume 5, No 3 (2016) pp. 24-28
Abstract
BaTiO3 (0 ≤ x 0.5) nano crystalline powders were synthesized by Ba(NO3)2, TiO(NO3)2, and aspartic acid (fuel) in a combustion method with heating at 550 °C for 6 hours. This process remarkably reduced the synthesis time and less energy consumable to obtain BaTiO3. The structure of BaTiO3 nano powders wereconfirmed by x-ray diffraction. The average crystallite size was determined from X-ray line broadening analysis by using the scherrer equation. The surface morphology of the synthesized product was observed by SEM studies. The formation of the product BaTiO3 was confirmed by FTIR studies. The synthesis and crystallization were followed by thermochemical techniques (TGA/DTA) studies. The synthesized materials showed reasonable electrical conductivity. These results indicates that assisted combustion method is a promising method to prepare nanocrystallite BaTiO3 anode material for solid oxide fuel cell.
