摘要：

Improved ionic conductivity of electrolytes is necessary for solid oxide fuel cells, meant for the development of efficient and clean energy devices. This study is focused on the enhancement of ionic conductivity in Ca-doped and Ca-La co-doped cerium oxide (ceria) electrolytes for intermediate-temperature solid oxide fuel cells (ITSOFCs). The co-doped ceria electrolytes, LCDC20 (Ce0.8La0.1Ca0.1O2- delta), exhibited enhanced ionic conductivity of 1.06 x10- 1 S cm- 1 at 1073 K, when compared to conventional yttria-stabilized zirconia (YSZ) electrolytes, and has lower activation energy of 1.02 eV. Also, these co-doped electrolytes showed decreased sintering temperatures, which amounts to cost-effective electrolyte materials for IT-SOFCs.
