Design of Convergent Flow Channel Applied to Sediment Microbial Fuel Cells

A sediment microbial fuel cell (SMFC) is a device that converts organic matter to electricity using microorganisms as the biocatalyst. Concerning the design and application of the flow channel in biotechnology and biomedical technology attracting more attention but rarely applied to MFC, a concept of using the convergent flow channel with/without plates would be applied to the SMFC for testing the power performance in this study. Result shows that a higher Reynolds number will be utilized a larger power generation will be produced. The convergent flow channel with plates can provide a more stable power generation than that case of without plate. These findings will be useful to the improvement of SMFCs.
