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
El mundo está abandonando gradualmente la dependencia excesiva de la energía procedente de combustibles fósiles en favor del descubrimiento, el desarrollo y la utilización de diversas formas de energía renovable. Uno de los avances es el uso de celdas de combustible microbianas (MFC). Se trata de un biorreactor que aprovecha la actividad microbiana presente en la sustancia orgánica de un sistema electroquímico para generar electricidad. En este estudio, se utiliza miel cruda como fuente de combustible para fabricar un dispositivo de MFC de doble cámara utilizando tabiques de arcilla. Se realizaron seis diluciones de miel cruda en la celda 1 (2 %), la celda 2 (5 %), la celda 3 (20 %), la celda 4 (40 %), la celda 5 (60 %) y la celda 6 (80 %). Tras catorce días en los que se realizaron dos experimentos, las densidades de corriente máximas obtenidas fueron de 270,2 mA/m2, 583,7 mA/m2, 654,0 mA/m2, 351,3 mA/m2, 140,5 mA/m2, 64,8 mA/m2, con las correspondientes densidades de potencia máximas de 99,2 W/m2, 215 W/m2, 247,0 W/m2, 123,1 W/m2, 49,8 W/m2, 22,5 W/m2 para la celda 1, la celda 2, la celda 3, la celda 4, la celda 5 y la celda 6, respectivamente. Se determinó que la miel cruda diluida puede utilizarse como fuente de combustible para crear una MFC.
