| 摘 要： | 研究以碳纤维毡为阳极，采用不同的表面改性方式对微生物燃料电池（MFC）产电效率的影响，并通过塔菲尔曲线（Tafel）和慢速扫描循环伏安法（SSCV）研究了碳纤维毡表面经不同改性处理后作为阳极的电化学行为。结果表明．碳纤维毡经丙酮浸泡（CZ—C）和热处理（CZ-H）后，最大输出功率从763mW／m2上升到896mW／m2，提高了17％；电化学测试证实碳纤维毡热处理后阳极交换电流密度提高，且氧化峰电位正移、峰电流增大。

| Abstract: | The effects of surface-modified carbon felt as anodes were investigated in single-chamber mem- braneless air-cathode microbial fuel cells （MFCs）. The electrochemical behaviour of the treated anodes was studied using Tafel and slow scan cyclic voltammograms MFC was enhanced with anodes modification by cleaning （SSCV）. The results indicated that the performance of with acetone （CZ-C） and heating in air （CZ-H）. The maximum power density of CZ-H anode （896 mW/m2） was 17% higher than CZ-C （763 mW/m2）. The elec- trochemical measures show that the CZ-H anode exhibited larger exchange current density, more positive anodic peak potential and higher anodic peak current. |
