摘要: 分析了微生物燃料电池的研究现状和影响其产电性能的主要因素,以及阳极活化过电势影响电池产电性能的过程,综述了从改善阳极电流-电势关系角度提高微生物燃料电池产电性能的研究进展. 分析认为,改善阳极电流-电势关系的关键是增加交换电流密度和增强异相电子传递,具体方法包括选择最适的阳极材料、优化阳极表面物理化学性质、筛选高效产电菌. 未来可从优化阳极材料几何结构、筛选高电催化活性产电菌及深入研究产电菌胞外电子传递过程的限制因素,如纳米导线与胞外细胞色素的作用机理等方面加强研究,优化微生物燃料电池产电性能.

Abstract: Recent research advances in microbial fuel cell and the major influential factors on the cell power generation are reviewed. The effect of anodic activation overpotential on cell performance is analyzed. The latest research progress on promotion of its power output by optimizing anodic current-potential curve is summarized. The key measures include increasing exchange current density and enhancing heterogeneous electron transfer, which can be achieved by selecting optimal anodic materials, optimizing the anode surface physicochemical properties and screening efficient anodic electrogens. Anodic materials with advanced geometric structures and highly efficient electrogens, and further understanding on the limiting factors of microbial extracellular electron transfer processes, such as the interactions between nano wire and extracellular cytochrome, will be needed in the future development.

Key words: microbial fuel cell, power generation performance, anodic activation overpotential, optimization
