Microbial Fuel Cell as New Renewable Energy for Simultaneous Waste Bioremediation and Energy Recovery

Abstract

Microbial fuel cell (MFC) is an outstanding technology recently creating the headlines relating to energy and environment field that been discovered since the earlier 20th century. It has been furthered implemented for energy renewable through simultaneous bioremediation of wastes. MFC works by converting chemical energy store in the waste into electrical energy with the help of selected microorganisms. Regarding to this, the principle of bioremediation was applied using MFC as the renewable energy where the microorganisms consume the substrate thus generating electrical energy. Many studies done by researches are mostly focusing on MFC utilizing waste and measuring the power generation on different type of MFC but lack of studies on the effect of series and parallel circuit in MFC setup and how does it differentiate the outcome of the studies. This paper reviews the history, working principle, design of MFC, classification of different substrates and its power output and the effect of series and parallel circuit of MFC setup for simultaneous bioremediation and energy recovery.
