Behaviour of Microbial Fuel Cell in a start-up phase

A Single-Chamber Microbial Fuel Cell (SCMFC) was constructed and run in a sequential feed-and-draw cycle operation. Anaerobic mixed bacterial culture and wastewater obtained from a local municipal wastewater treatment plant were used as biocatalysts and media, respectively. The SCMFC behaviour in a start-up phase was examined using the electrical potential (voltage) profiles, and further evaluated for the electricity generation and organic reduction. The voltage profile, developed during the early stages of the SCMFC run, was characterised by two prominent voltage peaks, which gradually fused into one peak.
