中文摘要：

以乙酸钠为燃料,制作涂层型三维复合阳极并组建铁碳布空气阴极微生物燃料电池。以铁网为三维框架,将碳毡覆盖至其上,并使用碳粉和30%PTFE溶液的混合液作为涂料在阳极表面添加涂层。将制作好的自制涂层型三维阳极和铁网分别组装微生物燃料电池,测试了铁网单独作为阳极时电池的产电性能,以及涂层含量和配合比对微生物燃料电池产电性能的影响。结果表明,相比铁网阳极,自制涂层型三维阳极能有效地提高电池的产电性能;涂层的含量和配合比均对电池产电性能有较大影响;当碳粉和PTFE的含量分别为750 mg和10 m L时,即配比为75∶1时,电池的产电性能最好,表观内阻为190 W,最大比功率为5 189.4 m W/m3。

英文摘要：

Sodium acetate was used by the microbial fuel cells with three- dimensional coating composite anode and Network Rail was used by the three-dimensional coating composite anodeas frameworkto cover the carbon felt on it. A mixture of toner was used and 30% PTFE solution was added as a coating on the anode surface. The Network Rail alone was used as the anode to test the electrical performance of the microbial fuel cells, and the impact of the coating content was researched, and ratio on the production of microbial fuel cell electdcal performance. The results show that compared to iron mesh anode, an anode made of three-dimensional coating can effectively improve the electrical properties of the battery capacity; contents and mix of coatings have a greater impact on the electrical properties of the battery; when the content of the toner and PTFE is 750 mg and 10 mL, ratio of 75 ： 1, Microbial Fuel Cells shows the best electrical perfomance, with the apparent resistance of 190 Ω, and the maximum power density is 5 189.4 mW/m3.
