Experimental study of bioelectricity-microbial fuel cell for electricity generation: Performance characterization and capacity improvement

Energy trending lately shown the need of new possible renewable energy. this paper studies about the capability and capacity generating of electricity by using bio-electricity-microbial fuel cell (bio-mfc). bio-mfc is the device that converts chemical energy to electrical energy by using microbes that exist in the sewage water. the energy contained in organic matter can be converted into useful electrical power. mfc can be operated by microbes that transfer electrons from anode to cathode for generating electricity. there are two major goals in this study. the first goal is to determine the performance characteristics of mfcs in this application. specifically we investigate the relationship between the percentages of organic matter in a sample results in higher electricity production of mfcs power by that sample. as a result,the sewage (wastewater) chosen in the second series experiment because the sewage (wastewater) also produced the highest percentage of organic matter which is around 10%. due to these,the higher percentage of organic matter corresponds to higher electricity production. the second goal is to determine the condition under which mfc work most efficiently to generating electricity. after get the best result of the combination for the electrode,which is combination of zinc and copper (900mv),the third series of experiments was coducted,that show the independent variable was in the ambient temperature. the reasons of these observations will be explained throughout the paper. the study proved that the electricity production of mfc can be increased by selecting the right condition of sample type,temperature and type of electrode. © 2017 penerbit utm press. all rights reserved.
