| 英文摘要 | a bi-layered composite cathode of la0.8sr0.2mno3 (lsm)-ysz and lsm-la0.4ce0.6o1.8 (ldc) was fabricated for anode-supported solid oxide fuel cells with a thin ysz electrolyte film. the cell with the bi-layered composite cathode displayed better performance than the cell with the corresponding single-layered composite cathode of lsm-ldc or lsm-ysz. at 650 degrees c, the cell with the bi-layered composite cathode gave a higher maximum power density than the cells with the single-layered lsm-ldc and lsm-ysz composite cathodes, by 52% and 175%, respectively. the impedance spectra results show that the thin lsm-ysz interlayer not only improves the cathode/electrolyte interface but also reduces the polarization resistance of the cathode. the activation energy for oxygen reduction on the bi-layered composite cathode is much smaller than that on lsm-ysz composite cathode, and it is suggested that the special redox property of ce4+/ce3+ in ldc facilitates the oxygen reduction process on the bi-layered composite cathode. the cell with the bi-layered composite cathode operated quite stably during a 100 h run.
