Evaluation of Activated Carbon Electrodes as Anodes in a Microbial Fuel Cell Using Shewanella Putrefaciens
In this work, three types of activated carbons were evaluated as electrodes in the anode chamber of a two-chamber microbial fuel cell (MFC). The evaluation was applied using a pure Shewanella Putrefaciens culture due to its gram-negative characteristics. In the cathode chamber, a platinum electrode...

| description |
In this work, three types of activated carbons were evaluated as electrodes in the anode chamber of a two-chamber microbial fuel cell (MFC). The evaluation was applied using a pure Shewanella Putrefaciens culture due to its gram-negative characteristics. In the cathode chamber, a platinum electrode was used, and a Nafion® 117 proton exchange membrane was selected as a separator of both chambers. The activated carbons were obtained from different precursors (coffee husk, commercial coal, and mineral coal), with different microporous and surface properties. From the voltage and current measurements, it was found that the cell power values varied between 0.008 mW and 0.045 mW. The electrode obtained from chemical activation of coffee husk with H3PO4 at 450 °C (Q) showed the best electrochemical behaviour and highest power values. This result may be mainly related to the macroscopic morphology and mesopores that improve the wettability of the surface by the medium thought carbonaceous material. SEM images showed a better biofilm formation, larger filaments of the bacteria, and micro-beds formation over the surface of bio-anode Q, which improved the interaction with the microorganism, its metabolism, and electrons extracellular transfer. Therefore, activated carbon from coffee husk could be considered as a promising material for electrodes of microbial fuel cells. |

Se utilizó un cultivo de Shewanella putrefaciens puro debido a sus características gran-negativa. En la cámara catódica se utilizó un electrodo de platino y Nafion® 117 como membrana de intercambio de protones para separar las dos cámaras. Los carbones activados seleccionados presentaron diferentes precursores (cisco de café, carbón comercial, y carbón mineral), con diferentes morfologías y propiedades porosas y superficiales. A partir de las mediciones de voltaje y corriente se encontró que los valores de potencia de la celda variaron entre 0.008 mW y 0.045 mW. El electrodo preparado utilizando carbón activado a partir de cisco de café (Q) presentó el mejor comportamiento electroquímico y valores de potencia más altos; este carbón se obtuvo a partir de la activación de cisco de café con H3PO4 a 450 °C. La morfología macroscópica de este carbón activado permitió una mejor migración del medio de cultivo acuoso hacia los macroporos y posteriormente mesoporos que mejoran la mojabilidad de la superficie. Las microfotografías SEM mostraron una mejor formación de la biopelícula, filamentos más largos de la bacteria y la formación de microlechos en el bio-ánodo Q, que favoreció la interacción con el microorganismo, facilitando su metabolismo y la transferencia extracelular de electrones. Por tal motivo, el carbón activado a partir de cisco de café podría ser considerado como un material prometedor para su implementación como electrodos en celdas de combustible microbiana.application/pdfapplication/pdfapplication/xmlengspaengspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/10468/9277https://revistas.uptc.edu.co/index.php/ingenieria/article/view/10468/9278https://revistas.uptc.edu.co/index.php/ingenieria/article/view/10468/9503Copyright (c) 2020 Diana-Marcela Vanegas-Hernández; Mónica-Liliana Cardona-Aristizabal; Zulamita Zapata-Benabithehttp://purl.org/coar/access_right/c_abf135http://purl.org/coar/access_right/c_abf2Revista Facultad de Ingeniería; Vol. 29 No. 54 (2020): Continuos Publication; e10468Revista Facultad de Ingeniería; Vol. 29 Núm. 54 (2020): Publicación Continua; e104682357-53280121-1129activated carbonanodic chambercarbonaceous materialsmediators microorganismShewanella Putrefacienstwo chambers cellscámara anódicacarbón activadoceldas dos cámarasmateriales carbonososmicroorganismos mediadoresShewanella PutrefaciensEvaluation of Activated Carbon Electrodes as Anodes in a Microbial Fuel Cell Using Shewanella PutrefaciensEvaluación de electrodos de carbón activado como ánodos de una celda de combustible microbiana usando Shewanella Putrefaciensinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a218http://purl.org/coar/version/c_970fb48d4fbd8a85Vanegas-Hernández, Diana MarcelaCardona-Aristizabal, Mónica LilianaZapata-Benabithe, Zulamita001/14261oai:repositorio.uptc.edu.co:001/142612025-07-18 11:53:37.443metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
