摘要:
采用柠檬酸盐燃烧法和固相反应相结合的方法制备BaCe0.8In0.1Y0.1O3-δ(BCIY)和掺杂Ta的BaCe0.7Ta0.1In0.1Y0.1O3-δ(BCTIY)电解质粉体,在200 MPa压力下干压成型后在不同温度下烧结成电解质片,并使用X射线衍射仪(XRD)、扫描电子显微镜(SEM)和电化学工作站分别对样品的物相、微观结构和电导率进行了表征.XRD结果显示,1 000℃煅烧5h的BCIY和BCTIY均表现出单一的钙钛矿相.收缩率和SEM结果显示,BCIY在1 250℃下就可以烧结致密,掺杂Ta的BCTIY在1 350℃下也可以烧结致密.在空气和湿润的H2气氛下BCTIY的电导率比BCIY的略有降低.在CO2和沸水环境下,BCTIY比BCIY明显表现出较好的化学稳定性.研究结果表明:BCTIY有望成为中低温固体氧化物燃料电池稳定的电解质材料.
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.
