摘　　要：将化学相容性良好的SrMo_(0.94)Fe_(0.06)O_(3-δ)(SMF)与Gd_(0.2)Ce_(0.8)O_(1.9)(GDC)进行复合,制备成SOFC阳极材料,研究以甲烷为燃料的情况下单电池功率输出性能,借助电化学工作站测试了电池的电化学阻抗,分析了单电池的运行稳定性和阳极侧的积碳情况。结果表明,随着GDC含量逐渐增多,阳极的极化电阻先增加后减小,含50 wt%GDC复合阳极的单电池获得了最大功率密度值112.4 mW·cm^(-2);能谱显示阳极内存在部分积碳现象,使得单电池输出性能偏弱,而GDC的添加能够减弱阳极的积炭行为。研究成果可为甲烷燃料气下的阳极研究提供参考和借鉴。SrMo_(0.94)Fe_(0.06)O_(3-δ)(SMF)and Gd_(0.2)Ce_(0.8)O_(1.9)(GDC)with good chemical compatibility were combined to prepare SOFC anode.The power output performance of single cell was studied when methane was used as fuel.The electrochemical impedance of the cell was tested by electrochemical workstation,and the stability of single cell and carbon deposition at anode side were analyzed.The results show that the polarization resistance of anode increases first and then decreases with the increasing amount of GDC,and the maximum power density of single cell is obtained to be 112.4 mW·cm^(-2) when the cell contains 50 wt%of GDC composite anode.Partial carbon deposition revealed by the energy spectrum in the anode is the primary cause of the instability of the single cell output.However,the addition of GDC can reduce the carbon deposition behavior of the anode.The results of this study can provide useful reference for the anode research when anode is fed with methane gas.
