  • 摘要: 为了降低构建微生物燃料电池（MFCs）的成本，比较了以碳毡和碳布作为阴极材料，在阴极利用功能微生物作为催化剂时电池的产电性能。结果表明，两电池启动时间基本相同，20 d左右达到稳定，但稳定期碳布作阴极的电池电压比碳毡作阴极的电池电压高出了60 mV左右。碳毡和碳布作阴极时，电池在10 d和20 d的最大功率密度分别由10.24和11.14 mW/m2提升到了18.18和30.15 mW/m2，相应内阻则分别由1 000和600 Ω降到了250和200Ω。循环伏安法（CV）显示两材料单独做电极时氧化还原情况相似，扫描电镜（SEM）观察到两者不同表面特性导致碳毡对污泥附着强于碳布，进而使氧气传递受到限制，产电降低。
    Abstract: To decrease the cost of MFCs,electricity generation characteristics of two MFCs using carbon felt and carbon cloth as biocathode materials with functional species as catalyst were investigated.The results show that the starting time of the two MFCs was almost the same,about 20 days,but the voltage of the former one was 60 mV lower than the latter one.The maximum power density of the two MFCs at 10 and 20 days increased from 10.24,11.14 mW/m2 to 18.18,30.15 mW/m2,while the internal resistance decreased from 1 000,600 Ω to 250,200 Ω,respectively.The redox condition of two biocathode materials was similar in the cyclic voltammogram.Scanning electron microscope results show that the two materials have different surface characteristics,carbon felt is more likely to adhere to the sludge,which may generate bad effects on DO diffusion and electricity production.
