This proof-of-concept study describes the enhanced performance efficiency of the dual-chambered microbial fuel cell equipped with the fabricated unmodified ceramic membranes and ceramic membranes modified with 5 % and 10 % (w/w) durum wheat semolina in comparison with the commercially available Nafion 117 membranes. The chemical oxygen demand removal efficiencies were determined to be 85.6 ± 0.1, 72.1 ± 0.2 and 68.6 ± 0.1 % for microbial fuel cell equipped with 10 % (w/w) semolina-modified, 5 % (w/w) semolina-modified and unmodified ceramic membrane, respectively, which indicated the improved wastewater treatment efficiency with increasing content of semolina. Preliminary studies showed that the 10 % (w/w) semolina-modified ceramic was cost-effective (64 USD/m) with improved water uptake, good proton mobility, low oxygen diffusion in addition to the enhanced power and current density output. The semolina-modified ceramic membranes have the potential to become a cost-effective alternative for the high-efficiency production of bioelectricity using microbial fuel cells.
这项概念验证研究描述了双室微生物燃料电池在配备制造的未改性陶瓷膜和用 5%和 10%（w/w）硬质小麦粗粒粉改性的陶瓷膜时的增强性能效率，与市售的 Nafion 117 膜相比。化学需氧量去除效率分别为 85.6±0.1%、72.1±0.2%和 68.6±0.1%，对于配备 10%（w/w）粗粒粉改性、5%（w/w）粗粒粉改性和未改性陶瓷膜的微生物燃料电池而言，这表明随着粗粒粉含量的增加，废水处理效率得到了提高。初步研究表明，10%（w/w）粗粒粉改性陶瓷具有成本效益（64 美元/平方米），具有改善的吸水性、良好的质子迁移率、低氧气扩散率以及增强的功率和电流密度输出。粗粒粉改性陶瓷膜有可能成为使用微生物燃料电池高效生产生物电能的具有成本效益的替代品。
