The quest for developing sustainable energy devices has put microbial fuel cells (MFCs) at the forefront of research in recent years. However, the use of synthetic polymer electrolyte membranes (PEMs) such as Nafion is a compromise in the sustainability of this technology. A novel eco-friendly composite PEM has been developed using poly(vinyl alcohol) (PVA) and k-carrageenan (kC) as membrane precursors. Cation exchangers such as vermiculite and imidazole-grafted vermiculite were augmented to the base membrane PVA-kC for developing PEM, called VPC and IPC, respectively. The proton mass transfer of VPC and IPC increased by 57 and 38%, while their oxygen mass transfer decreased by 45 and 44%, respectively, with respect to PVA-kC. Double-chambered MFCs were deployed with the developed PEMs, namely, PVA-kC (PMFC), VPC (VMFC), IPC (IMFC), and commercial Nafion (NMFC), for synthetic wastewater treatment in the aerated cathode configuration and dye decolorization with a ferricyanide cathode. The highest power density of 182 mW•m −3 was obtained with VMFC, followed by IMFC (164 mW•m −3 ), NMFC (145 mW•m −3 ), and PMFC (128 mW•m −3 ), in the aerated cathode MFC. The decolorization percentage increased in the order of PMFC (49%) < NMFC (55%) < IMFC (58%) < VMFC (65%). The cation-exchanger-augmented PVA-kC membrane can be used as a suitable alternative to Nafion in MFCs.

Some of the most popular technologies for wastewater sanitation, still face serious limitations related to high energy consumption requirements. In this context, microbial fuel cells (MFCs) constitute a promising approach since they do not require aeration and produce electricity at the same time. Limitations for these devices, however, are related to the cost of the constituents and the functionality of the arrangement. In this work, a semi‐cylindrical ceramic MFC was designed and constructed using a low‐cost commercial ceramic handcraft as a membrane, carbon felt, carbon cloth, and carbon cloth/activated carbon in different arrangements for the anode and cathode components. The best results were obtained using carbon felt as an anode and a cathodic zone built with carbon felt in which void regions were filled with activated carbon. This arrangement produced 85 mWm−2 for each cell. Evaluating the performance of the MFC in a modular system with eight cells using a different number of separations inside the module and different electrical connections, resulting in a 4‐compartment module that produced 90 mWm−2 with one single module and 95 mWm−2 with a serial arrangement of two modules.
