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
