阳极微生物的固定方式对微生物燃料电池性能的影响

Effects of anodic microbial immobilization method on performance of microbial fuel cell

研究了一种将微生物包埋在导电水凝胶中制备成微生物燃料电池(microbialfuelcell,MFC)阳极的新方法,该方法可以增加阳极上微生物的数量,并使多数微生物处于分散状态以利于代谢的扩散.该方法构建的阳极用在MFC中,显示了良好的效果.其最高功率密度和工作电压分别为0.243W/m^2和0.350V,比使用传统阳极的MFC分别高出89.843%和16.667%;其内阻则为263.780Ω,比使用传统阳极的MFC低78.973%.

A new method of preparing microbial fuel cell anode by embedding microorganisms in conductive hydrogel was studied.The method could change the population and distribution state of anodic microbial.The anode has been applied in MFC,and better results have been obtained.Its maximum power density and operating voltage (0.243 W/m^2,0.350 V) was 89.843% and 16.667% higher than those of the MFC using anode prepared by absorbing method,respectively.While the former's internal resistance (263.780 Ω) was 78.973% lower than the latter.This work may provide a novel anodic microbial enrichment method for improving the performance of MFC.
