微生物燃料电池高效产电的研究进展

结合微生物燃料电池研究进展,从提高微生物燃料电池的产电性能出发,讨论了目前微生物燃料电池发展的主要限制因素和应用前景.对影响微生物燃料电池产电性能的4个主要影响因素,电池构型、阳极室(电活性微生物、阳极材料)、阴极室(电子受体、催化剂)、阴阳极分隔材料进行了分析.认为目前对于低成本的电极材料和构型的扩大研究较少,微生物燃料电池由于其成本较高、产能较低,仍然难以进行实际的扩大应用.开发出低成本的电极材料和催化剂,并在实际应用中将其与其他水处理技术进行耦合应是是未来微生物燃料电池的研究重点.在此基础上,建立和优化微生物燃料电池数学模型,深入研究堆叠式微生物燃料电池产生的电压反转的原因也会对未来这一技术的改进提供可靠的帮助.

Research Progress of High Efficiency Power Generation for Microbial Fuel Cells

Based on the latest research progress of microbial fuel cells, this paper started with improving the electricity generation performance of microbial fuel cells, the main limiting factors and application prospects of current microbial fuel cell development were discussed. The four main influencing factors of MFCs on electricity generation performance, configuration, anode chamber (electroactive microorganisms, anode materials), cathode chamber (electron acceptors, catalysts) and separator materials for cathode and anode were analyzed. The development of low-cost electrode materials or catalysts, and coupling it with other water treatment technologies in practical applications should be the focus of future research of microbial fuel cells. On this basis, the establishment and optimization of microbial fuel cell mathematical models, and in-depth study of the reasons for the voltage inversion generated by stacked microbial fuel cells will also provide reliable help in the future improvement of this technology.
