Synthesis of barium cerate by co-precipitation method using a new precipitation agent for solid oxide fuel cells

Barium cerate (BaCeO3, BCO) has been studied as a promising material for application as an electrolyte in solid oxide fuel cells. In this work , BaCeO3 powder has been prepared via coprecipitationmethod using [pydc] [pyda] = LH2 , pydc = 2,6-pyridine dicarboxylate, Pyda = 2,6-pyridinediammine, complex as a new precipitating agent , under ultrasonicirradiation and BCO powder characterized by x-ray powder diffraction ( XRD) , scanningelectron microscopy (SEM ) , energy dispersive x-ray ( EDAX) spectrometer. The average particle size have been observed was about 54 nm with spherical shape
