Abstract
Microbial fuel cells including multiple electrodes, and systems of such fuel cells, are provided. An exemplary fuel cell includes a population of exoelectrogenic microbes and at least two anodes in an anode chamber, and a cathode in a cathode chamber. A path exists between the chambers for conducting hydrogen ions and each anode is connected to the cathode by a separate external circuit. Electrical output from the fuel cell is maximized by optimizing the microbe population, achieved by dynamically controlling the sub-populations at each of the multiple anodes. Systems comprising multiple such fuel cells connected by a dynamically reconfigurable fluidics system provide further optimization.
