Energy generation in a Microbial Fuel Cell using anaerobic sludge from a wastewater treatment plant

Scientia Agricola
In microbial fuel cells (MFCs), the oxidation of organic compounds catalyzed by microorganisms (anode) generates electricity via electron transfer to an external circuit that acts as an electron acceptor (cathode). Microbial fuel cells differ in terms of
