Resumen
A MICROBIAL FUEL CELL (MFC) IS A SUSTAINABLE DEVICE THAT PRODUCES ELECTRICITY. THE MAIN COMPONENTS OF MFC ARE ELECTRODES (ANODE & CATHODE) AND SEPARATORS. THE MFC S PERFORMANCE IS ASCERTAINED BY MEASURING ITS POWER DENSITY. ITS COMPONENTS AND OTHER PARAMETERS, SUCH AS CELL DESIGN AND CONFIGURATION, OPERATION PARAMETERS (PH, SALINITY, AND TEMPERATURE), SUBSTRATE CHARACTERISTICS, AND MICROBES PRESENT IN THE SUBSTRATE, ALL INFLUENCE ITS PERFORMANCE. MFC CAN BE SCALED UP AND COMMERCIALIZED USING LOW-COST MATERIALS WITHOUT AFFECTING ITS PERFORMANCE. HENCE THE CHOICE OF MATERIALS PLAYS A SIGNIFICANT ROLE. IN THE PAST, PRECIOUS AND NON-PRECIOUS METALS WERE MOSTLY USED. THESE WERE REPLACED BY A VARIETY OF LOW-COST CARBONACEOUS AND NON-CARBONACEOUS MATERIALS. NANO MATERIALS, ACTIVATED COMPOUNDS, COMPOSITE MATERIALS, HAVE ALSO FOUND THEIR WAY AS COMPONENTS OF MFC MATERIALS. THIS REVIEW DESCRIBES THE RECENTLY REPORTED MODIFIED ELECTRODES (ANODE AND CATHODE), THEIR IMPROVISATION, THEIR MERITS, POLLUTANT REMOVAL EFFICIENCY, AND ASSOCIATED POWER DENSITY.
