The effects of electrode spacing on the performance of microbial fuel cells under different substrate concentrations
In this study, the electricity generation and organic removal in microbial fuel cells (MFCs) were examined for electrode spacing (ES) covering 5.8, 10.2, 15.1, and 19.5 cm, and for each ES the MFCs were discharged with a series of influent substrates (CODin). Results indicate that organic removal was related to CODin but not to ES. Best chemical oxygen demand (COD) removals of ...
