“…It was observed a biofilm on the electrode surface when bacterial cells are colonized at the anode. The PD of the newly generated electrode with biofilms is 26.8% higher than the plain graphite electrode [145]. Nevertheless, a hybrid of 10% GO and MnO 2 utilizing as a catalyst at cathode generated the highest 148.8 mW per unit area showing the greatest performance among other concentrations of GO [30].…”

The focus of microbial fuel cell research in recent years has been on the development of materials, microbes, and transfer of charges in the system, resulting in a substantial improvement in current density and improved power generation. The cathode is generally recognized as the limiting factor due to its high-distance proton transfer, slow oxygen reduction reaction (ORR), and expensive materials. The heterogeneous reaction determines power generation in MFC. This comprehensive review describes-recent advancements in the development of cathode materials and catalysts associated with ORR. The recent studies indicated the utilization of different metal oxides, the ferrite-based catalyst to overcome this bottleneck. These studies conclude that some cathode materials, in particular, graphene-based conductive polymer composites with non-precious metal catalysts provide substantial benefits for sustainable development in the field of MFCs. Furthermore, it also highlights the potentiality to replace the conventional platinum air cathode for the large-scale production of the next generation of MFCs. It was evident from the experiments that cathode catalyst needs to be blended with conductive carbon materials to make cathode conductive and efficient for ORR. This review discusses various antifouling strategies for cathode biofouling and its effect on the MFC performance. Moreover, it also depicts cost estimations of various catalysts essential for further scale-up of MFC technology.

“…On the other hand, various electrocatalysts, such as platinum (due to its strong reducing activity and ability to increase the cathodic reaction rate) have been used to overcome the poor cathode function to a great extent in MFCs. However, such a catalyst is not suitable due to its high price and low stability 18 . Therefore, cost‐effective catalyst replacement should be considered.…”
