Abstract

A logic-based maximum power point tracking (MPPT) and LabVIEWTM interface for digitally controlled variable resistive load were developed and applied to a continuously operating flat-plate microbial fuel cell (FPM). The interaction between the designed MPPT algorithm and electrochemically active microbial performance on the electrode was demonstrated to track the maximal performance of FPM system. MPPT could dynamically derive the optimal performance from varied operating conditions of FPM such as organic concentration, flow rate and sampling interval, and produce a maximum power density of 88.0 Wm-3. The results could provide essential information to build an automatic control strategy to achieve the maximum performance from field scale microbial fuel cells for applications to sustainable bioenergy recovery from various biomass feedstocks.
