A microbial Fuel cell (MFC) is an environmental energy system for generating electricity from organic waste stream by treating detrimental pollutants in it. It is well-known that relative configurations of bioanode to cathode affect performance and electrochemistry of MFCs, but its quantitative effects on them are poorly understood. To investigate the influence of the distance on performance and electrochemistry MFC, different configurations of bioanode relative to cathode were tested. In a MFC with the 0.6 mm of horizontal distance between anode and cathode greatly increased power density up to 1,613 mW/m2-cathode comparing with 989 mW/m2-cathode in the 1.1 mm. As the distance increased, anode resistance was decreased and cathode resistance was increased. The 0.1 mm of horizontal distance between anode and cathode decreased power density, possibly due to oxygen penetration to the bioanode. |
