Resumen

Agricultural waste has increased rapidly in recent years due to increased food production, which has risen due to the increase in the world population. On the other hand, the high cost of energy consumption and scarcity of this sound in remote communities has caused the scientific community to look for new ways to sustain electricity. For this reason, the main objective of this research is to observe the potential of artichoke waste as fuel in single-chamber microbial fuel cells using carbon and zinc electrodes. An average maximum power density of 220.271 ± 11.174 mW/cm2 was achieved in an average current density of 5.841 ± 0.285 A/cm2 on the tenth day, with an average maximum voltage of 0.795 ± 0.025 V and an average maximum electric current of 1.980 ± 0.0.072 mA. These electric flies were obtained on the tenth day, where the microbial fuel cells operated at a pH of 4.351 ± 0.161 with an electrical conductivity of 127.844 ± 8.512 mS/cm and an electrical resistance of 40.314 ± 6.813 Ω. The single-chamber microbial fuel cells with artichoke waste were connected in series, producing a 2.35 V voltage necessary to light an LED light.
