Abstract

A promising environmentally friendly bioenergy device called a microbial fuel cell (MFC) uses bacterial biofilms as biocatalysts to convert organic matter into power.Because MFCs provide potentially new prospects for sustainable energy production from biodegradable and reusable waste materials, their design and use have drawn significant attention. However, novel fabrication methods should be needed for an effective functioning of Microbial fuel cell. The present study explores the concepts of nanotechnology principles for MFC fabrication which can be used to enhance the performance of MFC. The integration of nanotechnology principles into MFC fabrication offers exciting prospects for advancing sustainable energy and environmental technologies. Methods for improving MFC performance by altering the conventional fabrication techniques of the components for rapid transfer of electrons, improved conductivity, corrosion resistance, biofilm adhesion and biocompatibility with nanotechnology principles has discussed.

Role of nanomaterials like nanoparticles, nano tubes and nanocomposites mainly polymeric nanocomposites in fabrication technology explored clearly. A further study will help in addressing the main challenge in scaling up MFCs, which is the external energy required to begin the circuit to extract energy and investigating the long-term impact of nanocomposite-based MFCs on ecosystems.Continued research and innovation in this field are essential for realizing the full potential of nanomaterial-based MFCs in practical applications.
