Barium cerate (BaCeO3, BCO) has been prepared as electrolyte for low and intermediate temperature of solid oxide fuel cells. In this study, Barium cerate nanoparticles has beensynthesized by a new method using [(Ce2(pydc)4 (H2O)4 ].pyda.H ]2.2H2O ( 1 ) , Where [pydc ] [pyda] = LH2, pydc = 2,6-pyridine dicarboxylate , pyda = 2,6- pyridinediammine andCe(NO3).6H2O complexes as precursor, under ultrasonic irradiation. The characterization ofthe Ce(III) complex was performed using elemental analysis, FT-IR and Uv- Vis spectroscopes, andX-ray crystallography, SEM ,EDX and TG/DTA analysis. Then thecomplexes were treated under ultrasonic irradiation .Thermal decomposition of as prepared compound in ambient atmosphere leads to BCO Characterization of BCO was performed by XRD, scanning electron microscopy (SEM) , energy dispersive x-ray analysis ( EDX ) . The average particle sizes have been observed was about 63 nm with spherical shape
