Photos and Videos of Microbial Electrolysis Cells (MECs)/BEAMR systems researched in the Logan lab

	A single chamber MEC with a brush anode and a flat carbon cathode, shown with a reference probe. See the paper by Call & Logan (2008).
	A new, high performance two-chamber 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).

	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 data logging multimeter is used to monitor voltage in the circuit containing a resistor. From the voltage and resistor information, we can calculate current.
