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.

直接碳固体氧化物燃料电池（DC-SOFC）银基阳极具有高化学稳定性和抗硫抗积碳性能，然而受制于较差的催化性能，使得DC-SOFC的电化学性能一直无法让人满意。锶钴掺杂铁酸镧（LSCF）是一种催化性能佳，且兼具电子电导和离子电导的电极材料。通过LSCF修饰DC-SOFC的银基阳极（银-钆掺杂的氧化铈，Ag-GDC），显著提高了银基阳极的催化性能和相应的电池输出性能。在850 ℃，对应的DC-SOFC的最大功率密度由224 mW/cm2提高264 mW/cm2。相应的半电池阻抗谱、电极材料的微观形貌和晶型结构、与恒电流放电测试表明，在LSCF修饰后，Ag-GDC的极化阻抗由0.543 Ω·cm2降低至0.373 Ω·cm2，电极的微观形貌和晶型结构稳定，对应电池的燃料利用率由51.3%提升至57.9%。因此，LSCF修饰的Ag-GDC是一种性能良好且化学稳定的DC-SOFC理想阳极材料，有望推动DC-SOFC技术的进一步发展。

直接碳固体氧化物燃料电池（DC-SOFC）银基阳极具有高化学稳定性和抗硫抗积碳性能，然而受制于较差的催化性能，使得DC-SOFC的电化学性能一直无法让人满意。锶钴掺杂铁酸镧（LSCF）是一种催化性能佳，且兼具电子电导和离子电导的电极材料。通过LSCF修饰DC-SOFC的银基阳极（银-钆掺杂的氧化铈，Ag-GDC），显著提高了银基阳极的催化性能和相应的电池输出性能。在850 ℃，对应的DC-SOFC的最大功率密度由224 mW/cm2提高264 mW/cm2。相应的半电池阻抗谱、电极材料的微观形貌和晶型结构、与恒电流放电测试表明，在LSCF修饰后，Ag-GDC的极化阻抗由0.543 Ω·cm2降低至0.373 Ω·cm2，电极的微观形貌和晶型结构稳定，对应电池的燃料利用率由51.3%提升至57.9%。因此，LSCF修饰的Ag-GDC是一种性能良好且化学稳定的DC-SOFC理想阳极材料，有望推动DC-SOFC技术的进一步发展。

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.
