研究了用不同类型的陶瓷膜制成的微生物燃料电池（MFCs），以寻找一种低成本的质子交换膜替代品。mfc以新鲜的人尿作为燃料。叶蜡石和陶瓷的性能最好，功率密度分别为6.93和6.85 W m−3，莫来石和氧化铝的功率密度分别为4.98和2.60 W m−3。结果表明，生物膜的生长和活性取决于所使用的陶瓷膜的类型。最有利的条件是在陶器mfc。陶瓷膜的性能与其物理化学性质有关，并通过环境扫描电镜和能量色散X射线能谱仪进行了表征。莫来石、陶器、叶蜡石和氧化铝的成本估计分别为13.61、4.14、387.96和177.03英镑/平方米。结果表明，陶瓷和莫来石是市购质子交换膜的良好替代品，这使得MFC技术在发展中国家得以实现。
Microbial fuel cells (MFCs) made with different types of ceramic membranes were investigated to find a low‐cost alternative to commercially available proton exchange membranes. The MFCs operated with fresh human urine as the fuel. Pyrophyllite and earthenware produced the best performance to reach power densities of 6.93 and 6.85 W m−3, respectively, whereas mullite and alumina achieved power densities of 4.98 and 2.60 W m−3, respectively. The results indicate the dependence of bio‐film growth and activity on the type of ceramic membrane applied. The most favourable conditions were created in earthenware MFCs. The performance of the ceramic membranes was related to their physical and chemical properties determined by environmental scanning electron microscopy and energy dispersive X‐ray spectroscopy. The cost of mullite, earthenware, pyrophyllite and alumina was estimated to be 13.61, 4.14, 387.96 and 177.03 GBP m−2, respectively. The results indicate that earthenware and mullite are good substitutes for commercially available proton exchange membranes, which makes the MFC technology accessible in developing countries.
