An Overview of Microbial Fuel Cell Technology for Sustainable Electricity Production

Membranes, Journal Year: 2023, Volume and Issue: 13(11), P. 884 - 884

Published: Nov. 17, 2023

The over-exploitation of fossil fuels and their negative environmental impacts have attracted the attention researchers worldwide, efforts been made to propose alternatives for production sustainable clean energy. One proposed alternative is implementation bioelectrochemical systems (BESs), such as microbial fuel cells (MFCs), which are environmentally friendly. MFCs devices that use bacterial activity break down organic matter while generating electricity. Furthermore, can produce bioelectricity from various substrates, including domestic wastewater (DWW), municipal (MWW), potato fruit wastes, reducing contamination decreasing energy consumption treatment costs. This review focuses on recent advancements regarding design, configuration, operation mode MFCs, well capacity (e.g., 2203 mW/m2) (i.e., H2: 438.7 mg/L CH4: 358.7 mg/L). this highlights practical applications, challenges, life-cycle assessment (LCA) MFCs. Despite promising biotechnological development great should be implement them in a real-time commercially viable manner.
