Polyether ether ketone was sulphonated polyether ether ketone (SPEEK) and utilized as a proton exchange membrane (PEM) in a single chamber MFC (SCMFC). The SPEEK was compared with Nafion® 117 in the SCMFC using Escherichia coli. The MFC with the SPEEK membrane produced 55.2% higher power density than Nafion® 117. The oxygen mass transfer coefficient (K(O)) for SPEEK and Nafion® 117 was estimated to be 2.4 × 10(-6)cm/s and 1.6 × 10(-5)cm/s, respectively resulting in reduced substrate loss and increased columbic efficiency (CE) in the case of SPEEK. When the dairy and domestic waste water was treated in SPEEK-SCMFC, fitted with a membrane electrode assembly (MEA), a higher maximum power density was obtained for dairy waste water (5.7 W/m(3)). The results of this study indicate that SPEEK membrane has the potential to greatly enhance the efficiency of MFCs.
聚醚醚酮经磺化得到聚醚醚酮磺酸盐（SPEEK），并作为质子交换膜（PEM）应用于单室微生物燃料电池（SCMFC）中。在以大肠杆菌为燃料的 SCMFC 中，SPEEK 与 Nafion® 117 进行了对比。SPEEK 膜的微生物燃料电池产生的功率密度比 Nafion® 117 高 55.2%。SPEEK 和 Nafion® 117 的氧传质系数（K(O)）分别估计为 2.4×10(-6)cm/s 和 1.6×10(-5)cm/s，这导致 SPEEK 情况下底物损失减少，库仑效率（CE）提高。当采用膜电极组件（MEA）的 SPEEK-SCMFC 处理乳制品和生活废水时，乳制品废水中获得了更高的最大功率密度（5.7 W/m(3)）。本研究结果表明，SPEEK 膜有可能极大地提高 MFC 的效率。
