Studies on the effects of pre-firing and sintering temperature on NSDC nanocomposite electrolytes
文献摘要：
Solid oxide fuel cells(SOFCs)technology,with fuel flexibility,is one of the most promising power generation technology.However,the high operating temperature of SOFCs has hindered their commercial applications.As a crucial requirement to enhance its performance,SOFCs electrolytes should operate at a low temperature.Car-bonate/ceria composites are developed as electrolytes for low operating temperature SOFCs,and a better un-derstanding of the mechanism of its ionic conductivity serves this purpose.In this work,ceria-carbonate composite electrolyte,Na2CO3/samarium doped ceria(NSDC)were synthesized by the co-precipitation method.The synthesized electrolytes were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS),and UV-Vis spectroscopy.The XRD and SEM results showed that the sintered NSDC nanocomposite comprised a single-phase dense electrolyte structure.The crystallite size of the NSDC nanocomposite was greatly affected by the different pre-firing temperatures and different sintering tem-peratures.Also,the ionic conductivity of the prepared NSDC nanocomposite electrolytes was strongly dependent on the pre-firing and sintering temperatures.The NSDC nanocomposite electrolytes were pre-fired at 950℃and 650℃and sintered at 1200℃and 900℃respectively,had ionic conductivity in H2 and air high as 0.36 S/cm and 0.3 S/cm.
