Microbial Fuel Cells (MFCs)

Microbial Fuel Cells (MFCs) are innovative bioelectrochemical devices that utilize microorganisms to convert organic matter into electricity. These systems are a promising alternative for sustainable energy production, wastewater treatment, and bioremediation. By leveraging the natural metabolic processes of bacteria, MFCs provide a renewable and environmentally friendly solution for power generation. MFCs operate by using electrogenic bacteria that break down organic substrates and release electrons in the process. Where bacteria consume organic material and release electrons. electrons combine with protons and an electron acceptor (usually oxygen) to form water. Separates the chambers and allows proton flow while preventing oxygen diffusion. Conduct electricity, enabling electron transfer to generate current. Separate anode and cathode chambers connected by a proton exchange membrane (PEM).Higher efficiency but more complex in structure. Require electron shuttles like methylene blue or ferricyanide to transport electrons.
