Studies and Characterization of Electrical Properties of Microbial Fuel Cells Using Cow

Abstract

newline ABSTRACT Bio-batteries and MFCs represent a completely new, long-term durability and ecological way to promote the generation of sustainable energy, due to rapid depletion and escalation of prices of conventional fuel, community looking for an alternative source of energy which can be responsible and reproduced in an economical manner and keeping this view in mind the study has been taken to produce electrical energy from wastes like cow excreta (dung and urine). Batteries were made using various electrode pairs. Results indicated that the performance of Cand#8210;Zn electrode pair represents minimum RInt and better performance than other for both dung and urine. Electrolyte concentration was also another factor for electricity generation that plays an important role. The concentration of DW 50% in dung (solution) and 100% concentration of urine give maximum performance. Based on the results obtained from bioand#8210;batteries, for different types of MFCs (aerobic, anaerobic, airand#8210;anode, and airand#8210;cathode) was developed. Maximum performance of MFC was observed in airand#8210;cathode MFC. The investigation revealed that single chamber MFCs with the airand#8210;cathode configurations made by Cand#8210;Zn electrode pair could be used to produce electricity. The airand#8210;cathode MFCs made by dung and urine produced highest OCV 1.075 V and 1.425 V is corresponding to pH 8.8 and 10 at 10 days and 22 days respectively. In this research demonstrated that cathode aeration could be an energy efficient method for providing an active oxygen supply for MFC application.
