INVESTIGATION AND V-I CHARACTERISTICS OF SUBSTRATE FOR MFC: CASE STUDY OF RAW HONEY

Abstract

The world is gradually shifting from the over-reliance on fossil fuel energy to the discoveries, development, and use of various forms of renewable energy. One advancement is towards the use of Microbial Fuel Cells (MFCs). This is a bioreactor that makes use of microbial activity present in the organic substance in an electrochemical system to generate electricity. In this research, raw honey was utilized as the fuel source for fabricating a double-chambered MFC device using clay partitions. Six dilutions of the raw honey were made into Cell 1 (2 %), Cell 2 (5 %), Cell 3 (20 %), Cell 4 (40 %), Cell 5 (60 %), and Cell 6 (80 %). After fourteen days with two experiments carried out, the maximum current densities obtained were 270.2 mA/m2, 583.7 mA/m2, 654.0 mA/m2, 351.3 mA/m2, 140.5 mA/m2, 64.8 mA/m2, with the corresponding maximum power densities of 99.2 W/m2, 215 W/m2, 247.0 W/m2, 123.1 W/m2, 49.8 W/m2, 22.5 W/m2 for Cell 1, Cell 2, Cell 3, Cell 4, Cell 5, and Cell 6, respectively. It was determined that raw honey that
