    Bruce Logan Professor, Department of Civil & Environmental Engineering, Penn State University Energy from water: Microbial fuel cell technologies meet salinity gradient energy January 30, 2013 | 4:00pm | ESB 1001 Abstract The ability of certain microorganisms to transfer electrons outside the cell has created opportunities for new types of energy generation including: microbial fuel cells (MFCs), to produce electrical power; microbial electrolysis cells (MECs), to produce fuels such as hydrogen and methane gases; microbial desalination cells (MDCs) to partially or fully desalinate water; and microbial reverse electrodialysis cells (MRCs) that can additionally be used to obtain salinity gradient energy. In an MFC, exoelectrogens oxidize organic matter and release electrons to the anode. These electrons flow to the counter electrode (cathode) where they combine with oxygen and protons to form water, generating current and power. Sustained current generation is possible using virtually any type of biodegradable organic matter. The current produced by exoelectrogenic microorganisms can also be boosted to electrochemically produce hydrogen gas at the cathode. The voltage needed (>0.2 V) is substantially smaller than that needed to electrolyze water. By including a stack of membranes into MFCs or MECs, sources of salt and fresh water can be used in the membrane stack to produce additional energy from this salinity gradients. Key findings in electromicrobiology and advances in the materials and architectures used to make these different types of bioelectrochemical and electrochemical systems will be presented.
