Metal mixed biochar electrodes for the generation of electricity with high power density in microbial fuel cell

The current analysis points on the available resources of lessening the expense of electrodes and diminishing climate contamination utilizing waste materials. The microbial fuel cell (MFC) ability was evaluated by utilizing electrodes made from Biochar. For scaling up low cost MFC electrodes were modified by using less expensive materials like Biomass. Electrodes were made of Copper (Cu), Cobalt (Co) extends blended in with groundnut shell wastes biochar materials after the carbonization process. Power output of electrodes were AC-Cu 173.20 mW m −2 ) and AC-Co 205.49 mW m −2 ). The open circuit potential of cobalt oxide modified electrodes showed 0.843 V. Our results showed that the activated groundnut shell wastes with AC-Co metal anode gives the greatest power yield. Subsequently, CS-Cu anodes are progressively suitable, have more prominent biocompatibility, viable and versatile for application in the microbial energy unit. Among these two proposed anodes, CS-Co electrode has a tremendous potential for most extreme performances and development a practical maintainable MFC.
