ABSTRACT

: Microbial fuel cell (MFC), one of the best alternative sources of energy production is a bio-electrochemical device that directly generates electricity by harnessing the power of respiring microbes to decompose organic substrates. This paper is aimed at the study of a microbial fuel cell which uses yeast as micro-organism to decompose the organic waste for generation of electricity. This gives a detailed report of a microbial fuel cell which works with a low cost proton exchange membrane. To study the functioning of microbial fuel cell, a dual chambered microbial fuel cell was constructed using cathode and anode chambers. Later, the microbial fuel cell construction was modified into series for a detailed study. Moreover, a study of current density, power density, voltage, current, power was conducted in the case of both MFC constructions. Key words: Microbial fuel cell, Cathode, Anode, Proton exchange membrane, Bio-electrochemical device.
