The growth in energy demand and dependence on fossil fuels represent significant environmental challenges, especially in rural communities with limited access to energy. In this context, biobatteries based on microbial fuel cells (MFCs) emerge as a sustainable alternative for power generation. The objective of the following study was to evaluate the effectiveness of biobatteries in the generation of electric energy by means of MCC. An experimental study with a quantitative approach and explanatory scope was carried out. MCCs made with graphite electrodes and local organic substrates were used. Instruments such as digital multimeters and UV-Vis spectrophotometers were used to record and measure electrical energy through voltage, current and substrate analysis. The results revealed that the biobatteries generate an average voltage of 0.7 to 1.2 V under controlled conditions. Variables, such as electrode type, were found to slightly influence system performance. Power generation was stable for five weeks. It is concluded that the biobatteries show a high efficiency in the generation of electric energy under experimental conditions, being viable for their implementation in rural areas as a sustainable energy solution.
