- Abstract:
- The BaCe0.8In0.1Y0.1O3-δ (BCIY and Ta doped BaCe0.7Ta0.1In0.1Y0.1O3-δ (BCTIY) electrolyte powders were successfully synthesized by citrate combustion and solid phase reaction method in this paper.Under the 200 MPa pressure dry-pressing molding,the electrolyte flakes were obtained by sintered at different temperatures.The phase of samples was analysed by the x-ray diffraction (XRD);the microstructure was obtained by scanning electron microscope (SEM).The electrochemical performance was measured by the electrochemical workstation.The characterization of XRD,SEM and electrochemical workstation demonstrated BCIY and BCTIY both with a single perovskite structure after 5 h at 1 000℃ calcination.Moreover,BCIY and BCTIY Could be dense sintered under 1 250℃ and 1 350℃,respectively.In addition,the conductivity of BCTIY is a little smaller than that of BCIY in the air and humid H2.Meanwhile,the chemical stability of BC-TIY is superior to that of BCIY in CO2 and boiling water environment.These results indicated that BCTIY could be stable electrolyte materials applied in intermediate temperature solid oxide fuel cells.
