A dual chamber microbial electrolysis cell (MEC) was used for
generating hydrogen gas from supernatant of sugar beet juice after
fermentation. High density carbon fibers (2293-A, 24A Carbon
Fiber, Fibre Glast Development Corp., Ohio, USA) integrated with
a stainless steel current collector was used for the anode in the
MEC. Two chambers were separated by an anion exchange membrane
(AMI-7001, Membranes International Inc., USA). Stainless
