Microbial fuel cell technology: Novelties for a clean future

The degree of civilization exhibited by a society is largely determined by its reliance on energy, and as traditional energy sources such as fossil fuels become scarcer, new technologies will be required to secure sustainable energy. Microbial fuel cell technology is one of the most creative ways to meet humanity's energy demands because it can generate electrical energy from carbon sources. The framework of the limitations limiting the dissemination of this technology has been used to explore in depth new designs and configurations that have been produced recently. Future developments and current applications of this technology in bioremediation investigations are explored. The use of microbial fuel cell technology as a microbial biosensor for the identification of environmental contaminants is particularly significant. However, for a clean and sustainable ecosystem, it is imperative to disclose the challenges associated with the future adoption of this technology.
