Abstract/Description

Capturing electrons in the cathodic chambers of microbial fuel cells (MFCs) is a typical limiting aspect of its performance. Recently, research on biocathodes has gained more interest as it allows circumventing the utilisation of exogenous and unstable mediators at a lower cost. It is shown here that the growth of oxygenic phototrophs as a biofilm, increases the current output by two fold. This was possible by forcing the biofilm to grow directly onto the cathode, thus, producing the oxygen directly where it was consumed. This enhancement of the cathodic efficiency was stable for over 30 days.
