Microbial Fuel Cells Turn Waste Into Electricity While Cleaning Water

Unlike conventional power generation, MFCs use bacteria that break down organic matter and generate electrons as part of their natural metabolism. These electrons can be tapped from the fuel cell by electrodes to create an electrical current. The review points out that wastewater, food waste and agricultural byproducts can all be used as a food supply for the bacteria and therefore as a sustainable fuel source for power production.
