Microbial Fuel Cell Produces Power- A Review Paper

Abstract

Fuel cell (MFC) is a bio-electrochemical device that attaches the power of breathing microbes to convert organic substrates directly into electrical energy. At its essential, the MFC is a fuel cell, which converts chemical energy into electricity using oxidation reduction reactions. The important difference of path is in the name, microbial fuel cells depend on living biocatalysts to facilitate the movement of electrons throughout their systems instead of the traditional chemically catalyzed oxidation of a fuel at the anode and reduction at the cathode.

The center Point of this review is to generate power using another fuel sources i.e. bacteria in wastewater. Microbial Fuel Cells have developed in the recent years as the next potential power source. In this review we will discuss about-  1) the basic principle of the how MFCs function, 2) the bacteria active in mediator-less MFC, 3) the necessary MFC components and their significance, 4) various MFC designs that have been projected as efficient arrangements, and 5) its potential operation in a large-scale wastewater treatment plant. All of the research is done & based on the latest development in this technology and will be used as reference for the understanding phase. A project outline is also presented with a risk analysis on building a small MFC model and to generate power.
