In 2005, two research groups independendy found that bacteria could produce hydrogen in an electrolysis process based on a microbial fuel cell (MFC) (Logan et al., 2008). The device is called a microbial electrolysis cell (MEC), and the microbes are exoelectrogens because they release electrons instead of hydrogen. The half reactions at anode and cathode of MFCs for conversion of hydrogen from acetate are ...

Sediment microbial fuel cells are an excellent precedent of MFC applied to power devices in remote marine and estuarine locations [109]. MFCs hold great promise to produce biofuels from renewable biomass sources. The electricity produced by MFCs can be used for the electrolysis of water to produce hydrogen. Or, more efficiently, hydrogen could be produced directly from biomass sources using the MEC process (see Section 2.6.1).
