Photos and Videos of Microbial Electrolysis Cells (MECs)/BEAMR systems researched in the Logan lab (updated 12-19-2007)
This is the first bio-electochemically  assisted microbial reactor (BEAMR) that was used to prove the feasibility of the MEC process. See the publication by Liu et. al. (2005) for more information

A new, high performance microbial electrolysis cell (MEC). The anode chamber is filled with graphite granules(shown with a red clip connector). The hydrogen gas evolves from the cathode(black clip) and is captured in the tube above. Gas flows through a respirometer to measure gas flow rate. (Photo by Shaoan Cheng).

A data logging multimeter is used to monitor voltage in the circuit containing a resistor.  From the voltage and resistor information, we can calculate total power output by the system.
