| 英文摘要 | La0.6Sr0.4Co0.2Fe0.8O3−δ-Gd0.2Ce0.8O2-δ (LSCF-GDC) composite material is co-synthesized by the in-situ sol-gel method for solid oxide fuel cell (SOFC) cathodes. For the in-situ sol-gel method, the composite precursors are mixed at the sol state, which makes more uniform mixture than the solid state. Both the co-synthesized and physically mixed LSCF-GDC composites have been investigated for phase homogeneity by TEM energy-dispersive X-ray spectroscopy mapping and backscatter electron image. The results indicate that the dispersion of LSCF and GDC at the nanometer and micrometer scale is more homogeneous in the co-synthesized composites. Electrochemical impedance spectroscopy measurements confirm that the in-situ synthesized composites show lower polarization resistance than the physically mixed composites. An anode-supported fuel cell consisting of the in-situ synthesized LFCS-GDC composite cathode demonstrates a maximum power density of 1068 mW cm−2 at 800 °C, which is promising for intermediate temperature SOFC systems. |
