| 中文摘要 | 以阳极开路电势和阳极内阻为评价指标,比较了碳纸、石墨和碳毡3种阳极材料的产电性能,考察了孔体积、表面积、孔径分布、表面粗糙度和表面电位5种阳极特性对微生物燃料电池产电性能的影响。结果表明,增加多孔电极的孔体积、表面积以及内孔径都可以提高阳极上的微生物量,并降低了阳极内阻;增加非多孔电极的表面粗糙度也可增大阳极上的微生物量,同时还能降低阳极的内阻。表面电位对阳极微生物富集和产电也有影响,对于初始电位分别为450、300和40 mV的阳极,产电稳定后其上的蛋白质含量分别为38、82和98μg/cm2,说明表面电位越低则生物量越高,内阻越小。; Taking anodic internal resistance and anodic open circuit potentials as evaluation indexes,the power generation performances of three anodic materials including carbon paper,graphite and carbon felt were compared.The influence of anodic characters such as the pore volume,surface area,aperture distribution,surface roughness and surface electric potential on the power generation performances of microbial fuel cell was investigated.The results show that the increasing of the pore volume,surface area and internal aperture of porous electrodes can increase biomass on the anode and decrease anodic internal resistance.The increasing of surface roughness of non-porous electrodes can also increase biomass on the anode and decrease anodic internal resistance.The surface electric potential has an effect on anodic microbial enrichment and power generation.When the initial potentials of anodes are 450 mV,300 mV and 40 mV,the total amounts of protein on these anodes are 38 μg/cm2,82 μg/cm2 and 98 μg/cm2,respectively.Therefore,lower surface potential results in higher biomass and lower anodic internal resistance.; 国家自然科学基金资助项目(20577027) |
