Microbial fuel cell is a newest type of fuel cells that can generate electricity from renewable biomass by means of microorganisms as biocatalysts. There are diverse factors that can be considered in the development and improvement of MFC performance. Among effective parameters in Microbial Fuel Cells, substrate types and electrode composition play a crucial role in its performance. In this study, a dual chamber MFC is fabricated to check its dual function of bioelectricity production and simultaneously wastewater treatment. The present work is an experimented investigation concerned with selection of the best pair of electrodes. The various combinations of anode/cathode materials as copper, zinc, aluminium and carbon for Microbial Fuel Cells has been systematically studied and out of which Zn/C pair gave higher voltage output of 1.24±0.001 V and current of 3.28±0.012 mA with Gudiyari nala wastewater. Simultaneously, analy...

It is a technique to produce bioelectricity from available organic waste. It is helpful to fulfill the lighting requirements of rural areas. The aim of our research work is to construct twocompartment system and to study various parameters like performance of the different combination of electrodes, optimization of pH and temperature. In this study, using bacteria as biocatalyst, the naturally found cow dung was used to generate an open circuit voltage of 0.84 ± 0.010 V and a current of 3.51 ± 0.620 mA. Optimization of various parameters shows that among different temperature range, 37°C temperature gives the highest voltage production of 0.84 ± 0.091 V and current of 3.08 ± 0.512 mA. In case of pH there are not any significant changes were found when pH range is changed. Although, pH 4.0 is found to be more efficient as it produces voltage of 0.90 ± 0.045 V and current of 4.85 ± 0.587 mA. Furthermo...
