Silver anode for direct carbon solid oxide fuel cell (DC-SOFC) has great chemical stability and resistance to sulfur and carbon deposition. However, the electrochemical performance of DC-SOFC is still unsatisfactory due to the poor catalytic performance. Strontium cobalt doped lanthanum ferrite (LSCF) is an electrode material with good catalytic performance as well as electronic and ionic conductivity. In this paper, silver anode (silver-gadolinium doped cerium oxide, Ag-GDC) was modified with LSCF to improve the catalytic performance of the silver anode and the output performance of the corresponding cell. At 850 ℃, the maximum power density of the corresponding DC-SOFC increases from 224 mW/cm2 to 264 mW/cm2. According to the results by impedance spectroscopy for the corresponding half-cell, microscopic morphology and crystal structure of the electrode material, and constant current discharge tests, the polarization resistance of Ag-GDC decreases from 0.543 Ω·cm2 to 0.373 Ω·cm2, the microstructure and crystal structure of the electrode become stable, and the fuel utilization of the corresponding cell increases from 51.3% to 57.9% after the LSCF modification. Therefore, LSCF-modified Ag-GDC is an ideal anode material for DC-SOFC with good performance and chemical stability, which is expected to promote the further development of DC-SOFC.
