Abstract
Chronoamperometric investigations with rotating disc electrodes (RDEs) were used to characterise the anodic half-cell of yeast powered microbial fuel cells using methylene blue (MB) as a mediator. Both convection and mediator adsorption were shown to affect the anodic current. A microbe–mediator limited reaction model was developed and shown to agree well with the experimental data. A power density of ∼150 μW cm–2 was achieved in a full cell, which represented a significant increase from prior reports on yeast-catalysed fuel cells. The increased power density was enabled by using high mediator concentrations and by controlling the mediator adsorption.
