中文摘要：
本文分别从电池启动过程、电极附着生物量、电极阻抗、电池性能等方面,比较了采用碳颗粒填充床、碳刷、碳颗粒-不锈钢网和碳颗粒-碳刷为阳极材料的微生物燃料电池的性能。结果表明,电池启动时间的长短及电极阻抗的大小顺序依次为：碳颗粒、碳颗粒不锈钢网、碳刷和碳颗粒-碳刷电极,而电极上附着生物量的多少呈相反顺序。碳颗粒填充床生物量最少,阻抗最大,因而其电池性能最低。而碳颗粒-碳刷复合电极上附着的生物量最多,阻抗最小,因此电池的性能最高。
英文摘要：
From the points of start-up processes,biomass attached on the electrode,anode impedances and cell performance,the four different electrode materials as carbon granules（C）, graphite fiber brush（GFB）,combination of carbon granules and stainless steel mesh（SS＋C） and combination of carbon granules and graphite fiber brush（GFB＋C） were used as anodes to compare their performance.The results showed that the sequence in the start-up time and anode resistances was as below：CSS＋CGFBGFB＋C,and the biomass attached on the electrode showed the opposite trend.The power density of MFC-C was the lowest duo to its least biomass content and the largest anode impedance and the power density of MFC-GFB＋C was the highest with the largest biomass and the least anode impedance.
