Exploring the key factors enhancing the microbial fuel cell performance

Microbial Fuel Cells are an emerging technology widely used for metabolizing organic matter by microorganisms to produce electricity. The exponential technology of MFC encompasses the potential achievements of power generation in addition to wastewater treatment, desalination and biosensor, etc. However, the prime bottlenecks of the process that affect application include unstable power supply and low production of power production. Hence to acquire efficient performance, the desirable properties like membrane in the cell membrane, microbes involved, and their respective metabolism influencing MFCs have been considered and discussed in the present review. Meanwhile, it is also essential to eliminate certain remarkable defies, including automation, cost, and performance encountered by the conventional MFC technology. Thus, pertinent integrated approaches enabling microscale MFCs, Ceramic or clay-designed MFCs, and CW- MFCs (Constructed wetland- Microbial Fuel Cells) employing rhizodeposition are highly promising in advancing MFC applications. Along with wastewater treatment, the MFCs utilize organic substrates as proficient medium for the growth of exoelectrogenic bacteria in wastewater. Thus, recent overview of MFCs developments for higher and inexpensive energy production encloses the utmost understanding of the factors mentioned above. The present review focuses on the development of different methodologies to enhance the important factors and applications of MFC technology. In addition, it also explains the cohesive, environmentally friendly prospects of MFCs with bioremediation, rhizodeposition influential treatments and desalination.
