摘　　要：以葡萄糖为碳源,研究不同浓度对微生物燃料电池产电性能的影响。结果表明:葡萄糖的较佳浓度范围为0.5~4.0g/L,启动时间3~6d,运行稳定,且持续时间长,葡萄糖浓度为0.5g/L的MFC的电动势为0.75V,电池内阻为47.8Ω,最大体积功率为5.3W/m^3;浓度为1.0g/L的MFC的电动势为0.71V,内阻为56Ω,最大功率密度4.0W/m^3;浓度为2.0g/L的MFC的电动势为0.70V,内阻为86Ω,最大功率密度为2.67W/m^3;浓度为4.0g/L的MFC的电动势为0.64V,内阻为99Ω,功率密度2.25W/m^3。The effect of glucose concentration on power-generation performance of microbial fuel cell （ MFC ） had been studied. The experimental results showed that Glucose concentration： 0.5-4.0g/L were better concentration range for power-generation performance of MFC, and start-up time needed 3-6 days. MFC in this situation can keep stable, and will last longer duration comparing other concentration. When the glucose concentration is 0.5g/L, the electromotive force of MFC is 0.75V, internal resistanceof imum is 47. 812, maximum volume power density is 5.3W/m3 ; at 1.0g/L, the electromotive force of MFC is 0.71V, the internal resistanc is 56Ω, maximum, volume power density 4.0W/m3 ; at 2.0g/L, the electromotive force of MFC is 0.70V, the internal resistance is 8612, the maximum power density is 2.67 W/m3 ; at 4.0g/L , the electromotive force of MFC is 0.64V, the internal resist- ance is 99Ω, power density 2.25W/m3. When glucose concentration is above 12%, it is impossible for MFC to start and generate power.
