HNEI researchers investigated the efficacy of microbial fuels cells for a variety of applications. To treat wastewater, a flow through microbial fuel cell was linked downstream from an anaerobic digester. Results showed the development of functionalized biofilms were possible under non-sterile environments and digestion rates that suggested microbial fuels to perform well as a polishing unit supporting anaerobic digestion. HNEI researchers also investigated enzymatic biocatalysts to convert chemical energy directly into electricity as a power source. Key technical thrusts pursued included development of macro-porous electrodes, standardized platforms for electrochemical characterization, and in-situ techniques to probe the chemical microenvironments of immobilized enzymes.
