摘　　要：利用机械混合及化学复合两种混合方式制备出用于微生物燃料电池(MFC)阴极的Mn O_2与活性炭导电材料的混合催化剂,混合质量比分别为1∶3,1∶1和3∶1。将以各催化剂制作的碳布阴极置于空气阴极MFC中运行,利用线性扫描伏安法测试碳布阴极的性能。研究表明,两种混合催化剂均在混合质量比为1∶1时具有最佳性能;化学复合催化剂MFC的最大功率密度达到336 m W/m^2,是单纯使用Mn O_2粉末时的2.51倍,优于机械混合的催化剂。The mixed catalysts of MnO= and activated carbon were prepared using mechanical mixing and chemical composing method for air-cathode of microbial fuel cells （MFCs）. And the composite proportion （MnOE：AC）of the mixed catalysts was 1：3,1：1 and 3：1, respectively. These catalysts were coated onto carbon cloth as air-cathode to test by linear sweep voltammetry （LSV）, and operated in air-cathode MFCs. The experimental results showed that the catalysts with feeding ratio of 1：1 displayed the best performance. The maximum power density was 336 mW/mE,which is higher than mechanical mixing one. Furthermore, it is 2.51 times as MnO2 powder MFC.
