Microbial Fuel Cells (MFC) are bio-electrochemical systems that generate electricity through microbial oxidation of organic material. Smaller MFC reactors have shown improved power output, making them suitable for portable applications. Electrode materials play a crucial role in MFC performance, with carbon-based materials being commonly used due to their biocompatibility and conductivity. Researchers are now turning to 3D printing technology to create electrodes, with Glass Screen Printed Electrodes (GSPEs) emerging as a potential solution to issues like biofouling. Graphene Quantum Dots (GQDs) have demonstrated superior properties compared to traditional materials, such as better surface area for microbial attachment and enhanced conductivity. In a recent study, GQDs were incorporated into electrodes using GSPEs technique to improve the performance of Microbial Fuel Cells (MFC). The evaluation included electrochemical testing like Cyclic Voltammetry and polarization studies. The study also utilized wastewater from Reverse Osmosis (RO) filter paper in the MMFC operation, showcasing the potential for sustainable energy generation from waste streams.
