摘要
不锈钢纤维毡因作为微生物燃料电池(microbial fuel cells,MFC)阳极材料具有高电导率、低成本和易于适用不同流态的优点而受到广泛的关注。本文通过构建不锈钢纤维毡阳极-活性炭空气阴极的MFC,探索不同孔径(5、20、40μm)的不锈钢纤维毡阳极对MFC性能的影响,结果表明,随着不锈钢孔径的增大,MFC的产电性能提高,孔径为40 um时,MFC产电性能达到最佳,最大输出电压0.53 V,内阻最低(188.3Ω),最大功率密度为0.80 W/m~2。对阳极菌落结构分析,结果表明,阳极主要菌属为Geobacter sp.和Sphaerochaeta sp.,分别占阳极生物群落的22.3%和18.0%。
