| Abstract | In this study, a two-compartment continuous flow microbial fuel cell (MFC) reactor was used to compare the efficiencies of cathode oxygenation by air and by hydrogen peroxide. The MFC reactor had neither a proton-selective membrane nor an electron transfer mediator. At startup, the cathodic compartment was continuously aerated and the anodic compartment was fed with a glucose solution. An increase of electrical power generation from 0.008 to 7.2 mW m−2 of anode surface with a steady-state potential of 215–225 mV was observed within a period of 12 days. The performance of the air-oxygenated MFC reactor progressively declined over time because of biofilm proliferation in the cathodic compartment. Oxygenation of the cathodic compartment using 300 mL d−1 of 0.3% hydrogen peroxide solution resulted in a power density of up to 22 mW m−2 (68.2 mA m−2) of anode surface at a potential of 340–350 mV. The use of H2O2 for oxygenation was found to improve the long-term stability of the MFC reactor. |
