Abstract

The contaminant and terminable potential of fossil fuels resulted in researchers finding an enduring and green energy source. Microbial fuel cells (MFC) are considered as a new alternative to lead people to a more sustainable, accessible, and green energy source that consumes wastes and other cheap resources. Some conventional MFCs include two chambers that acquire cathode or anode electrodes and an ion-exchange membrane. Microorganisms that exist on the anode surface are regarded as the only electrical energy production factor in the MFCs. The chemical energy is converted to electricity by the microbes and then conducted to an anode surface. The stretchable and flexible MFCs have been lately introduced to extend MFCs usages in different areas, e.g., portable devices and medical science. Some basic and construction methods and followers of flexible MFCs are considered as the most significant issues examined in the present study to help resolve future energy generation.
