The increase in the cost of electricity consumption over the last 20 years, coupled with the lack of electricity in remote towns, has driven the search for new ways to generate electricity at a low cost. In addition, the high production of granadilla has caused waste levels of this fruit to begin to contaminate the environment in places near sale or harvest. Microbial Fuel Cell (MFC) technology offers an opportunity to use granadilla waste as fuel to generate electricity economically. The research showed peak electric current and voltage values of 2.126 ± 0.072 mA and 0.2981 ± 0.017 V, respectively, in the MFCs on the twelfth day, operating with an electrical conductivity of 131.692 ± 3.511 mS/cm at a pH of 5.31 ± 0.161. The internal resistance found on the twelfth day was 41,857 ± 3587 Ω, whose power density was 284.761 ± 21,841 mW/cm2 at a current density of 5.507 A/cm2.

摘要

The increase in the cost of electricity consumption over the last 20 years, coupled with the lack of electricity in remote towns, has driven the search for new ways to generate electricity at a low cost. In addition, the high production of granadilla has caused waste levels of this fruit to begin to contaminate the environment in places near sale or harvest. Microbial Fuel Cell (MFC) technology offers an opportunity to use granadilla waste as fuel to generate electricity economically. The research showed peak electric current and voltage values of 2.126 ± 0.072 mA and 0.2981 ± 0.017 V, respectively, in the MFCs on the twelfth day, operating with an electrical conductivity of 131.692 ± 3.511 mS/cm at a pH of 5.31 ± 0.161. The internal resistance found on the twelfth day was 41,857 ± 3587 Ω, whose power density was 284.761 ± 21,841 mW/cm2 at a current density of 5.507 A/cm2.
