Abstract
Abstract In the present work the electrochemical behaviour of microbial cells from a biocathode microbial fuel cell (MFC) functioning with wastewater was evaluated by cyclic voltammetry. In-situ electrochemical assays were performed and, under the tested experimental conditions, the biocathode medium was found to be the most efficient for the cathodic catalysed electrochemical reduction of oxygen. Different controls using sterile media and membranes covering the electrodes were performed and compared with the regular biocathode results. In the biocathode chamber, the presence of bacteria was associated with the enhanced active redox processes and with the higher electrochemical reduction of oxygen activity. The present study is a contribution to the understanding of the viability and advantages of the biocathodes use in MFC.
Key findings
- The biocathode medium is the most efficient for cathodic catalyzed electrochemical reduction of oxygen.
- The presence of bacteria in the biocathode chamber enhances active redox processes and oxygen reduction activity.
- Sterile media and membrane-covered electrodes controls show reduced electrochemical activity compared to regular biocathode results.
