Carbon electrodes for bio-electricity generation in microbial fuel cells

Experiments carried out to find out optimum experimental conditions and electrode materials have been compiled with conventional carbon materials i.e. CC. GrR, CP and WC by taking in a microbial fuel cell setup as anode to select the best electrodes material among these. Dual chamber MFC filled with sewage waste-water as substrate was used for the comparative study of current and power production using different anode materials. The electrochemical properties of the electrodes have been investigated by cyclic voltammetry. During power production, stability of anodes along with COD, BOD removal efficiencies were also calculated. The SEM images taken after 45 days of the experiment confirm biocompatibility of anodes. The comparative study suggest better results with CC anode as compared to other anode materials.
