The microstructures and electrical properties of the electrolytes are analyzed by using XRD, SEM, XPS, Raman, electrochemical analysis and AC impedance spectroscopy. The XRD results showed that all samples have an almost single LSGM phase. SEM results show that the all samples have the dense structure. XPS results show a clear doublet structure in the narrow region scan of the core level La 3d3/2 and 3d5/2. The LSGM1520 has the higher ionic conductivity (0.22 S/cm) at 800°C. At 800°C, the open circuit voltages and maximum power densities of the Cell–LSGM1520, Cell–LBSGM03, Cell–LBSGM05, Cell–LCSGM03 and Cell–LCSGM05 electrolyte-supported cells were 0.95 V and 539 mW/cm2, 0.95 V and 500 mW/cm2, 0.94 V and 506 mW/cm2, 0.94 V and 567 mW/cm2, and 0.93 V and 547 mW/cm2, respectively. The Ohmic resistances of the Cell–LSGM1520, Cell–LBSGM03, Cell–LBSGM05, Cell–LCSGM03 and Cell–LCSGM05 cells measured at 800°C were 0.307, 0.31, 0.32, 0.25 and 0.272 Ω∙cm2, respectively. 吳玉娟 2017 學位論文 ; thesis 183 zh-TW |
