COMPARATIVE STUDIES ON DIFFERENT ELECTRODES TO IMPROVE PERFORMANCE OF MICROBIAL FUEL CELLS (MFC)

Abstract The main objective of this paper is to study the performance of the various combinations of electrodes for soil and cow dung slurry substrates which plays an important role in the Microbial Fuel Cells (MFC) for the generation of electricity. The present work is an experimentalstudy concerned with selection of the electrodes for the best performance of an MFC. The various combinations of anode/cathode materials like copper, zinc, aluminium, for MFCs has been systematically studied along with different substrate like cow dung, soil, and out of which Al/Al and Cu/Zngave higher voltage output. Keywords: Microbial fuel cell (MFC); Membranes, Mediators, Substrate, Electrodes.
