<br/><br/> Electricity production and modeling of microbial fuel cell (MFC)from continuous beer brewery wastewater was studied in this paper. A single air-cathode MFC was constructed, carbon fiber was used as anode and diluted brewery wastewater (COD = 626.58 mg/L)as substrate. The MFC displayed an open-circuit voltage of 0.578 V and a maximum power density of 9.52 W/m3 (264 mW/m2). Using the model based on polarization curve, various voltage losses were quantified. At current density of 1.79 A/m2, reaction kinetic loss and mass transport loss both achieved to 0.248 V; while ohmic loss was 0.046 V. Results demonstrated that it was feasible and stable for producing bioelectricity from brewery wastewater; while the most important factors which influenced the performance of the MFC are reaction kinetic loss and mass transport loss.
