摘　　要：以活性炭颗粒为阳极,气体电极为阴极,葡萄糖模拟废水为基质构建了上流式直接空气阴极单室生物燃料电池(UACMFC),在连续运行条件下考察了电池的产电性能和水力停留时间(HRT)对电池性能的影响。结果表明,UACMFC具有较好的产电能力和稳定性,在外阻为9000Ω条件下,最大输出电压为0.915V。HRT对生物燃料电池的产电性能和COD的去除效果均有影响,水力停留时间为8h时,电池的最大输出功率密度为44.3W·m-3(废水),COD去除率为45%。An upflow air-cathode microbial fuel cell （UACMFC）was constructed by using gas electrode as cathode, activated carbon particles as anode and glucose as the anode fed. The electricity generation of UACMFC and the effect of hydraulic retention time （HRT） on the performance of MFC were studied at the continuous operating conditions. The results demonstrated that UACMFC have good stability and performance. The maximum output voltage was 0.915 V at external resistance of 9 000 Ω.The performance of MFC and the removal rate of COD also can be affected by HRT. When HRT was 8 h, the maximum output power of UACMFC was 44.3 W. m^-3 （waste water）and the removal rate of COD was 45%.
