Abstract

This breakthrough study presents a revolutionary flow-based microbial fuel cell design that eliminates biofilm limitations through redox mediator technology. Using planktonic Shewanella bacteria with artificial redox mediators, the system achieves extraordinary current densities exceeding 40 mA/cm². The flow configuration enables continuous operation with superior mass transfer, resulting in unprecedented power performance compared to traditional biofilm-based systems.
