Progress and Recent Trends in Microbial Fuel Cells: A Comprehensive Guide

Microbial fuel cells (MFCs) have emerged as a promising technology for harnessing renewable energy from organic matter while simultaneously treating wastewater. This article delves into the captivating world of MFCs, exploring their progress and recent trends.

Fundamentals of Microbial Fuel Cells

MFCs utilize microorganisms to generate electricity through the breakdown of organic compounds. Microbes residing on the anode of the cell catalyze the oxidation of organic matter, releasing electrons. These electrons flow through an external circuit, generating electricity, and ultimately reach the cathode, where they combine with oxygen to produce water.
