Nafion(R)117作为最常用的质子交换膜，在双室微生物燃料电池中对生物发电和废水处理的前处理和生物污染的影响进行了研究。结果表明，使用经过处理的Nafion(R)117可获得最大发电功率，功率约为100 mW/m(2)。然而，未经处理的Nafion(R)117和生物污染的Nafion(R)117的最大发电功率分别为52.8 mW/m(2)和20.9 mW/m(2)。此外，经过前处理的Nafion(R)117的柱效分别是未经处理和生物污染的Nafion(R)117的2.32倍和4.15倍。结果表明，质子交换膜的前处理是达到更高功率所必需的，而生物污染是双室MFC中质子交换膜的主要障碍。皇冠版权所有(C)2012，氢能出版有限责任公司。爱思唯尔有限公司出版。保留所有权利。
Nafion (R) 117, as the most popular proton exchange membrane, has been studied with regards to the effect of pre-treatment and biofouling for bioelectricity production and wastewater treatment, in dual chamber microbial fuel cells. The obtained results showed that maximum generated power was obtained using pre-treated Nafion (R) 117, at approximately 100 mW/m(2). However, maximum generated power for untreated Nafion (R) 117 and biofouled Nafion (R) 117 were 52.8 mW/m(2) and 20.9 mW/m(2), respectively. Furthermore, the columbic efficiency of pre-treated Nafion (R) 117 was 2.32 and 4.15 times higher than untreated and biofouled Nafion (R) 117, respectively. Obtained results demonstrated that the pre-treatment of the proton exchange membrane is necessary to reach higher powers, and biofouling is a major obstacle for proton exchange membranes in dual chamber MFCs.
