Esta investigación tuvo como objetivo evaluar el uso de agua ácida de relave minero como sustrato para la generación de energía eléctrica a través de celdas de combustible microbianas de una cámara, a fin de buscar una alternativa de reúso de estas aguas y contribuir con tecnologías ecoamigables que logren el apaciguamiento de la alta demanda de energía eléctrica. Esta investigación fue aplicativa y de diseño experimental, siendo las variables el agua ácida de relave minero y la energía eléctrica. Se construyó una celda de combustible microbiana (CCM) de cámara única con cátodo de aire, que tuvo como electrodos una placa de grafito como ánodo y cátodo. Además, se midieron parámetros fisicoquímicos durante 30 días a temperatura ambiente (18 ± 2,2 ºC). El voltaje, corriente y turbidez, lograron valores pico de 0.65 ± 0.02 V, 1.83 ± 0.04 mA, 981.5 ± 13.44 NTU ...

The use of organic waste as fuel for energy generation will reduce the great environmental problems currently caused by the consumption of fossil sources, giving agribusiness companies a profitable way to use their waste. In this research, tomato waste with different percentages of sucrose (0-target, 5, 10, and 20%) was used in microbial fuel cells manufactured on a laboratory scale with zinc and copper electrodes, managing to generate maximum peaks of voltage and a current of 1.08 V and 6.67 mA in the cell with 20% sucrose, in which it was observed that the optimum operating pH was 5.29, while the MFC with 0% (target) sucrose generated 0.91 V and 3.12 A on day 13 with a similar pH, even though all the cells worked in an acidic pH. Likewise, the cell with 20% sucrose had the lowest internal resistance (0.148541 ± 0.012361 KΩ) and the highest power density (224.77 mW/cm2) at a current d...
