The aim of this study was to develop an economically viable clayware ceramic membrane that exhibits proton mass transfer comparable to the commercially available membrane (Nafion 117) for microbial fuel cell (MFC). The clayware ceramic membrane made from red soil was modified using cation exchangers like montmorillonite (MMT) and vermiculite (VC), and by spray coating of MMT composite with Nafion solution. Nafion‐117 (a commercial membrane) and membrane prepared using only red soil were used as a standard and control, respectively. Other membranes include 20% blend of MMT with red soil (SM); 20% VC with red soil (SV); 10% blend of each MMT and VC with red soil (SMV); and SM membrane spray‐coated with Nafion solution (SMN). The addition of cation exchangers enhances the performance of the clayware ceramic membranes as compared to the control, and coating of Nafion solution on SMN leads it to perform even better. Average open circuit voltage and average operating voltage for the SMN membranes were 670 ± 17.63 mV and 82 ± 5.69 mV, respectively, which are the best among all the fabricated membranes. The power density of the SMN membrane was 84.3 mW/m3 which is five times that of the control. The study demonstrates that SMN membrane can be used as an alternate for more costly polymeric membranes in MFC.

粘土陶瓷膜的改性以增强微生物燃料电池的性能

这项研究的目的是开发一种经济可行的陶土陶瓷膜,该膜表现出的质子传质与可用于微生物燃料电池(MFC)的膜(Nafion 117)相当。使用蒙脱土(MMT)和ver石(VC)等阳离子交换剂,并用Nafion溶液喷涂MMT复合材料,对由红土制成的陶土陶瓷膜进行了改性。Nafion-117(商用膜)和仅使用红壤制备的膜分别用作标准品和对照品。其他膜包括MMT与红土(SM)的20%混合;VC有20%的红壤(SV); 每种MMT和VC与红壤(SMV)的10%混合;然后用Nafion溶液(SMN)喷涂SM膜。与对照相比,添加阳离子交换剂可提高陶器陶瓷膜的性能,Nafion溶液在SMN上的涂覆使其性能更好。SMN膜的平均开路电压和平均工作电压分别为670±17.63 mV和82±5.69 mV,在所有制成的膜中是最好的。SMN膜的功率密度为84.3 mW / m3,这是控件的五倍。研究表明,SMN膜可以替代MFC中成本更高的聚合物膜。
