Components Used in Microbial Fuel Cells for Renewable Energy Generation: A Review of Their Historical and Ecological Development

Abstract

This review article addresses microbial fuel cells (MFCs) as a renewable energy source. Microbial fuel cells are bio-electrochemical systems that use exoelectrogenic bacterial communities under anaerobic conditions to convert chemical energy into electrical energy. These systems are attracting attention due to their potential to reduce overall energy consumption, produce zero carbon emissions, and exhibit high energy density. The rapid development of renewable energy sources has increased the potential for bioenergy, particularly MFCs, to become one of the most important energy sources of the future. In addition to energy production, MFCs show potential for bioremediation and efficient removal of various pollutants. While MFC technology currently has limited application at the laboratory level, it is expected to increase in commercial use in the near future and offers great potential in the areas of renewable energy and environmental sustainability. This review article focuses on the historical and ecological development of the components used in MFCs, examining in detail their evolution and use in MFCs for renewable energy production.
