摘　　要：本文采用电化学聚合法在碳毡表面沉积制备聚苯胺基改性阳极。通过傅里叶变换红外光谱(FT-IR)进行成分表征,用光学显微镜对改性电极表面形貌进行表征,并进行了一系列电化学测试。结果表明,聚苯胺和聚吡咯优异的电化学性能使电池的抗极化性能得到提高,最大输出功率密度提高了3倍左右,电池的整体性能得到改善。最后探讨了聚苯胺基改性阳极的作用机理。To prepare the polyaniline-based modified anode on the surface of carbon felt,the method of electrochemical polymerization has been utilized.The compositionis characterized by Fourier transform infrared spectroscopy（FT-IR）.Also the electrochemical performancehas beeninvestigated.Results show thatthe polarization resistance of the battery has been improved,and the maximum output power density has been increased about three times.In a word,the overall performance of the battery is improved.In the end of the paper,the mechanism of the polyaniline based modified anodeis discussed.
