摘　　要：微生物燃料电池(MFC)的阳极性能差,导致其输出功率较低,实际应用受到了极大的限制。针对这一问题,本文提出了一种基于多粒径碳组合构筑高性能阳极的方法,以40~60目、100目的活性碳与碳黑为原材料,在不锈钢基底上,制备了三维多孔阳极(CCB),同时在其制备过程中引入碳酸氢铵,获得了孔隙率更高的阳极(CCB-N)。表征实验结果表明,CCB、CCB-N与单一活性碳阳极(C40:40~60目、C100:100目)相比,不仅提高了比表面积,还增强了导电性。在产电性能方面,装配CCB-N的MFC最大功率密度达1831.7 mW/m^(2),比CCB、C40、C100分别提高了9.5%,24.8%和52.3%,这得益于碳酸氢铵辅助造孔,增大了阳极表面可供微生物利用的孔隙率。本研究制备的阳极有效提升了MFC性能,也为高性能阳极的构筑提供了一种新思路。Microbial fuel cell(MFC)has poor anode performance,which leads to low output power,and its practical application is greatly limited.In order to solve this problem,this paper proposes a multiple particle size of carbon composite building high-performance anode method,with 40~60,100 object of active carbon and carbon black as raw material,the stainless steel substrate,the preparation of the three-dimensional porous anode(CCB),at the same time introduced in the process of the preparation of ammonium bicarbonate,obtained the higher porosity anodic(CCB-N).The characterization experiment results show that CCB and CCB-N not only improve the specific surface area,but also enhance the electrical conductivity compared with the single activated carbon anode(C40:40~60 mesh,C100:100 mesh).In terms of electrical performance,the maximum power density of MFC equipped with CCB-N reached 1831.7 mW/m^(2),which was 9.5%,24.8%and 52.3%higher than that of CCB,C40 and C100,respectively.This was attributed to the addition of ammonium bicarbonate to pore formation,which increased the porosity of anode surface available for microbial utilization.The anode prepared in this study can effectively improve the performance of MFC,and also provide a new idea for the construction of high-performance anode.
