David Kilper / WUSTL PhotoAngenent and He's microbial fuel cell may be scaled up for industrial use.An environmental engineer at Washington University in St. Louis has created a device similar to a hydrogen fuel cell that uses bacteria to treat wastewater and create electricity. Lars Angenent, Ph.D., assistant professor of Chemical Engineering, and a member of the University's Environmental Engineering Science Program, has devised a microbial fuel cell which he calls an upflow microbial fuel cell (UMFC) that is fed continually and, unlike most microbial fuel cells, works with chambers atop each other rather than beside each other.
