Abstract: Methods and systems for microbial fuel cells with unproved cathodes are provided, in accordance with some embodiments, methods for microbial fuel cells with improved cathodes are provided. The methods comprising: abiotically reducing oxygen on a cathode having a catalyst layer bound to a gas diffusion layer using an anion conductive polymer, consequently accumulating Off at the catalyst layer, and reducing local pH by conducting the OH″ away from the catalyst layer, directly or by transport of anionic buffers that act as OH″ carriers, through the anion conductive polymer, in accordance with some embodiments, a system for microbial fuel cells is provided. The system comprising: a container, an anode, anode-respiring bacteria, and a cathode having a catalyst layer bound to a gas diffusion layer using an anion conductive polymer.
