Microbial fuel cell (MFC), one of the emerging topics of research, suffers from two chief limitations, low power generation and high cost of reactor materials. These problems limit its possibility of field scale implementation and commercialization. Hence, an attempt has been made in this study to highlight the utilization of lost cost ceramic material modified with mineral cation exchanger with various concentrations (10-50%) as separator along with studying the role of thickness and surface area in improving the overall performance of an MFC. The performance of the membranes with different thickness and kaolin concentrations was studied based on their proton exchange, ion transfer and oxygen diffusion capabilities. While, proton transfer coefficient was found to be highest in membrane of thickness 4 mm containing 30% kaolin, oxygen transfer coefficient was found to be lowest in the membrane of thickness 6 mm containing 50% kaolin. Thus, MFCs of optimised parameters with concentric anode chamber made with ceramic material were used to study the effect of membrane surface area on their performances. MFC with the highest membrane surface area showed highest power density, highest organics removal efficiency and least internal resistance. Thus, it was concluded from the results that high membrane surface area increases the performance efficiency of the MFCs by maintaining proper proton concentration on both side of the membranes. The results thus highlight the importance of a membrane in an MFC and how the presence of a cation exchanger can enhance the electricity generation.

Green process engineering, which is founded on the concepts of the process intensification approach, can make a significant contribution to industrial sustainability. Green process engineering refers to new equipment and procedures that are intended to result in significant improvements in chemical and other manufacturing and processing elements. It entails lowering production costs, equipment size, energy consumption, waste creation, as well as boosting remote control, information flow, and process flexibility. Membrane-based technology aids in the pursuit of these ideals, and the potential of membrane operations has recently been extensively acknowledged. The efficacy of fuel cells is dependent on the correct design of the electrodes and membrane, which allows for simple access to oxygen and protons. The use of non-precious catalytic electrodes based on recyclable carbon nanostructures is critical for producing clean energy and increasing the commercialization potential of fuel cells. Green hydrogen will play a significant part in future fuel supply chains, covering 15% to 20% of the world’s energy demands. A proton exchange membrane (PEM) fuel cell is one method, where hydrogen may be utilized to generate electricity. This paper begins by providing an overview of membrane electrolytes in fuel cells and the generation of energy. Moreover, the proton exchange membrane fuel cell (PEMFC) is regarded as one of the most promising power generators capable of providing clean energy sources, particularly for transportation and stationary cogeneration applications. Finally, it will shed light on the role of green or renewable hydrogen in future fuel cells and achievement sustainability.
