以不锈钢网为集流体,采用辊压工艺制备了Fe3O4质量分数分别为0％、2.5％、5.0％和7.5％的不锈钢网、活性炭粉和Fe3O4构成的复合阳极AcM、AcFeM1、AcFeM2和AcFeM3,研究了Fe3O4含量对单室无膜空气阴极微生物燃料电池(MFC)产电性能的影响,并通过塔菲尔曲线和阳极充电-放电测试研究了不同Fe3O4含量的阳极的电化学行为.结果表明,阳极Fe3O4质量分数由0％增加至2.5％、5.0％时,MFCs的最大输出功率和净电容电荷由AcM阳极的664 mW/m2和293.9 C分别上升至AcFeM1、AcFeM2电极的731 mW/m2和300.4 C、809 mW/m2和388.5 C,当Fe3O4含量继续增加至7.5％时,MFCs的产电效率和净电容电荷均减小,Fe3O4质量分数在5.0％时,MFCs性能最佳；电化学测试进一步说明Fe3O4质量分数在5.0％时,MFCs阳极的动力学活性最好.
