Though variations in electrolyte composition, cathode air flow rate and substrate concentrations would affect the electricity generation, but they were not as significant as the variations in external resistance. For experiments using sodium acetate as the electron donor, the maximum stable potential was raised from 130 to 331 mV when the external resistance was switched from 100 Ω to 1000 Ω; however, the corresponding current and power densities were decreased 74 and 32 %, respectively. The Columbic Efficiency (CE) was decreased from 27 to 4 %, and the half-saturation constant was also reduced from 277 to 147 mg/L COD. Adding the mixture of toluene/MTBE as the co-substrate of sodium acetate did not raise the maximum stable potential, but prolonged the period of that and enhanced the electricity generation. For MFCs using gasoline aqueous solution as the substrate, the performance of electricity generation was much worse than previous MFCs using sodium acetate. It was only 1.3 mV generated despite the gasoline was degraded. The degradation rate of components in gasoline was ethyl benzene > p-xylene > toluene > benzene > o-xylene > MTBE. The addition of sodium acetate as the co-substrate or neutral red as the electron shuttle both did raise the electricity generation. I-Yuang Hsu 許益源 2012 學位論文 ; thesis 103 zh-TW |
