浅谈微藻型微生物燃料电池技术进展

A Brief Discussion on the Progress of Microalgae-Based Microbial Fuel Cell Technology

微藻型微生物燃料电池(MFCs)是利用厌氧或兼性厌氧微生物的催化作用,将新能源与环境治理相结合的一种技术。典型的微生物燃电池是由阳极和阴极,以及一片质子交换膜所构成,微生物于阳极分解氧化燃料,并同时产生电子和质子,电子可经由外部导线到达阴极,而质子则通过质子交换膜到阴极,在阴极会消耗电子和质子与氧结合产生水,从而将化学能转化为电能,将未经净化的废水转化为清洁的饮用水和电源。微藻型MFC具有成本低、生物质价值高、二氧化碳封存率高、操作条件温和、耐有害物质、反应速率高等优点,微藻型MFC是一种高效、可持续的工艺。

Microalgae-based microbial fuel cells(MFCs)are a technology that combines new energy with environmental governance by utilizing the catalytic effect of anaerobic or facultative anaerobic microorganisms.A typical microbial fuel cell consists of an anode,a cathode,and a proton exchange membrane.Microorganisms on the anode decompose and oxidize the fuel,producing electrons and protons simultaneously.Electrons can travel to the cathode via external wires,while protons pass through the proton exchange membrane to the cathode.At the cathode,electrons and protons combine with oxygen to produce water,converting chemical energy into electrical energy,thus transforming unpurified wastewater into clean drinking water and a power source.Microalgae-based MFCs have advantages such as low cost,high biomass value,high carbon dioxide sequestration rate,mild operating conditions,resistance to harmful substances,and high reaction rates,making them an efficient and sustainable process.
