将不同PTFE含量的石墨/PTFE复合电极作为微生物燃料电池（MFQ）的阳极进行了测试。大肠杆菌）。结果表明，复合电极中PTFE的含量对MFC的发电效率有显著影响。具有优化的PTFE含量的复合电极，24%至36%（w/w），非常适合用作大肠杆菌催化的MFC的阳极。在不存在外源电子介体的情况下，以含30% PTFE的复合阳极和常规空气阴极为阳极的大肠杆菌催化MFC的功率密度为760 mW m（-2），比文献报道的大肠杆菌催化MFC的功率密度高得多。大肠杆菌MFC使用有效的电子介质。这些结果为开发低成本、高效的MFC阳极材料提供了重要的前景。(c)2006 Elsevier B.

The composite graphite/PTFE electrodes with a variety of PTFE contents were tested as anodes in microbial fuel cell (MFQ based on the biocatalysis of bacteria Escherichia coli (E. coli). It is shown that the PTFE content in the composite electrodes can significantly influence the efficiency of current generation of the MFCs. The composite electrodes with optimized PTFE contents, e.g., 24% to 36% (w/w), are well-suited to serve as anode of E coli-catalyzed MFCs. In the absence of exogenous electron mediators, E coli-catalyzed MFC with the composite anode containing 30% PTFE and a conventional air cathode exhibited a power density of 760 mW m(-2), which is even much higher than those reported in the literature so far for E. coli MFCs using efficient electron mediators. These results show significant prospects for developing low cost and effective anode of MFCs. (c) 2006 Elsevier B.V. All rights reserved.
