摘要
以乙酸钠为碳源,铁氰化钾溶液为电子受体,以普通双极膜(膜A)、特种双极膜(膜B)和质子交换膜(膜C)构建的微生物燃料电池进行产电性能的实验研究。得到如下实验结果:膜A开路电压为0.77V,最大体积功率密度为3.23W/m3,由线性拟合方程可知其内阻为91.22Ω;膜B电池的开路电压0.748V,最大体积功率密度为3.52W/m3,内阻为92.26Ω;膜C电池的开路电压为0.796V,最大体积功率密度为3.75W/m3,内阻为79.29Ω。结果表明:各种膜在微生物燃料电池产电性能方面相近。通过膜效率的分析,在微生物燃料电池中,采用离子交换膜替换价格昂贵的质子交换膜是可行的。
In this paper, performance of microbial fuel cell constructed film A, film B and film C, with acetate as carbon source, potassium ferricyanide solution as the electron acceptor, has been studied. The capacity of the microbial fuel cell electrical performance was tested and several membrane microbial fuel cell cost-effective was analyzed. The results show that： open-circuit voltage of membrane A is 0.77V, maximum volume power density is 3.23W/m3, it can be seen from the linear regression equation： the internal resistance is 91.22Ω; open circuit voltage of cell with membrane B is 0. 748V, maximum volume power density is 3.52W/m3 , the internal resistance is 92.26Ω; open circuit voltage of cell with membrane C is 0. 796V, maximum volume power density 3.75W/m3, the internal resistance 79.29Ω. Through the analysis of the membrane efficiency, it is feasible that the expensive proton exchange membrane is replaced by the ion exchange membrane in the microbial fuel cells.
