题目:Scaling Up Microbial Fuel Cells and Practical Limits in Power Production

时间:2017828日(周一)上午9:30 —1130

地点:城市水资源与水环境国家重点实验室612会议室

  

摘要:Substantial progress has been made in treating wastewater using anaerobic technologies such as microbial fuel cells (MFCs) that can also produce electricity. Two different designs have emerged based on tubular cells or plate-andframe (flat) geometries. For both cases, the choice of the electrode size and spacing can impact cathode packing densities and thus possible volumetric performance. The cathode has been the main focus of MFC research in recent years, with modifications of activated carbon cathodes that have resulted in power densities of 2.5 to 4.7 W/m2 in laboratory scale MFCs using acetate, and up to 0.8 W/m2 with typical low-strength domestic wastewater. How much higher could these power densities go? What are the limits? Based on an intra- and inter-laboratory comparisons of MFCs, it is now possible to understand the limits of power production both in terms of electrode area and volume. New data will be presented that examines limits in power production from the perspective of minimizing electrodes spacing while utilizing reactor configurations that promise to be effective in wastewater treatment.
