Performance of microbial Fuel cell under air Pumping to the cathode side

Abstract

Pumping air to the cathode chamber and its effect on the microbial fuel cell performance was detected. It was detected that increasing oxygen concentration has a positive value on the cell performance accompanied by increasing of chemical oxygen demand COD which is attributed to the growing of cultures that are nourished by oxygen in the cell. Generally, the performance of the cell was better in case of air purging with respect to the case of without purging.
