Yb-Doped BaCeO(3) and Its Composite Electrolyte for Intermediate-Temperature Solid Oxide Fuel Cells
BaCe(0.9)Yb(0.1)O(3−α) was prepared via the sol-gel method using zirconium nitrate, ytterbium trioxide, cerium nitrate and barium acetate as raw materials. Subsequently, it reacted with the binary NaCl~KCl salt to obtain BaCe(0.9)Yb(0.1)O(3−α)-NaCl~KCl composite electrolyte. The structure, morpholog...

Sumario: | BaCe(0.9)Yb(0.1)O(3−α) was prepared via the sol-gel method using zirconium nitrate, ytterbium trioxide, cerium nitrate and barium acetate as raw materials. Subsequently, it reacted with the binary NaCl~KCl salt to obtain BaCe(0.9)Yb(0.1)O(3−α)-NaCl~KCl composite electrolyte. The structure, morphology, conductivity and fuel cell performance of the obtained samples were investigated. Scanning electron microscope (SEM) images showed that BaCe(0.9)Yb(0.1)O(3−α) and NaCl~KCl combined with each other to form a homogeneous 3-D reticulated structure. The highest power density and conductivity of BaCe(0.9)Yb(0.1)O(3−α)-NaCl~KCl was 393 mW·cm(−2) and 3.0 × 10(−1) S·cm(−1) at 700 °C, respectively. |
