AbstractIn this paper, graphite felts were continuously electrochemically oxidized to increase the current generation in microbial fuel cells (MFCs). The treated and untreated graphite felts were utilized as anodes in MFCs and current production was compared. The current production on electrochemically treated graphite felt anodes was about 1.13 mA. 39.5% higher compared with that of MFCs containing untreated anodes. The results demonstrated that the electronic coupling between graphite felt electrodes and electrogenic bacteria could be enhanced by electrochemical oxidization of the electrodes. Further study showed that the newly generated carboxyl containing functional groups from electrochemical oxidization were responsible for the enhanced electron transfer, due to their strong hydrogen bonding with peptide bonds in bacterial cytochromes.
