Different microfiltration membrane (MFM), proton exchange membrane (PEM) and ultrafiltration membranes (UFMs) with different molecular cutoff weights of 1K (UFM-1K), 5K (UFM-5K) and 10K (UFM-10K) were incorporated into air-cathode single-chamber microbial fuel cells (MFCs) which were explored for simultaneous azo dye decolorization and electricity generation to investigate the effect of membrane on the performance of the MFC. Batch test results showed that the MFC with an UFM-1K produced the highest power density of 324 mW/m(2) coupled with an enhanced coulombic efficiency compared to MFM. The MFC with UMF-10K achieved the fastest decolorization rate (4.77 mg/L h), followed by MFM (3.61 mg/L h), UFM-5K (2.38 mg/L h), UFM-1K (2.02 mg/Lh) and PEM (1.72 mg/Lh). These results demonstrated the possibility of using various membranes in the system described here, and showed that UFM-1K was the best one based on the consideration of both cost and performance.
不同的微滤膜（MFM）、质子交换膜（PEM）和超滤膜（UFMs），其分子截断重量分别为 1K（UFM-1K）、5K（UFM-5K）和 10K（UFM-10K），被引入到空气阴极单室微生物燃料电池（MFC）中，以研究同时偶氮染料脱色和发电对 MFC 性能的影响。批处理测试结果表明，与 MFM 相比，带有 UFM-1K 的 MFC 产生了最高的 324 mW/m(2)的功率密度和增强的库仑效率。带有 UFM-10K 的 MFC 实现了最快的脱色率（4.77 mg/L h），其次是 MFM（3.61 mg/L h）、UFM-5K（2.38 mg/L h）、UFM-1K（2.02 mg/Lh）和 PEM（1.72 mg/Lh）。这些结果表明，在本文所描述的系统中使用各种膜是可行的，并且考虑到成本和性能，UFM-1K 是最佳选择。
