Microfabrication, the technology adopted in standard semiconductor manufacturing industry such as thin film deposition, photolithography, etching, has driven micro-electro-mechanical-system (MEMS) and lab-on-a-chip toward batch fabrication, low expense, and precisely controlled geometry. MEMS microbial fuel cells (MFCs), via miniaturization of an MFC to be in micrometer scale, are useful for a small-size power supply or lab-on-a-chip devices for scientific research on exoelectrogen. Besides applications as an energy converter, MEMS MFC is useful for scientific studies, including the mechanism of extracellular electron transfer (EET) of exoelectrogen, screening the electricity generation capability of individual exoelectrogen. Miniaturized MFC-on-a-chip devices also find application in biosensors for toxic chemical detection. This chapter illustrates a two-chamber configuration MEMS MFC. The MFC includes two chambers, anode and cathode chambers, separated by an ion exchange membrane, such as PEM (proton exchange membrane).
