"A Green Approach towards Production of Bioelectricity Using Microbial Fuel Cell "

Abstract

The performance of sodium chloride, potassium ferricynaide and potassium ferrocynaide cathodes on bioelectricity production was evaluated in dual chambered microbial fuel cell (MFC).The three MFCs with sodium chloride, potassium ferricynaide and potassium ferrocynaide cathodes were operated separately to elucidate the difference in power generation potential and chemical oxygen demand value.Effective power generation of magnitude 25223.880mW/m 2 for 24 hours and 31380.597mW/m 2 for 48 hours was noticed for fuel cell operated with sodium chloride cathode.Maximum power yield of value 9.125 (W/Kg CODR) for 24 hours, 11.36 (W/Kg CODR) for 48 hours and current density of 970.149 (mA/m 2 ) for 24 hours and 1082.090(mA/m 2 ) for 48 hours were recorded at 100 Ω resistor for sodium chloride cathode.The Chemical Oxygen Demand (COD) value was observed to decrease.
