Abstract
The development of a high-efficiency anode is essential for the use of microbial fuel cells. The metallic conductivity, corrosion resilience, low cost of conducting polyaniline (PANI) and recycled graphene (RGn) pique our interest. In this study, PANI-RGn nanoparticles are polymerized in situ on cotton fabric wrapped with aluminium mesh as the anode for a microbial fuel cell. The MFC was designed as a dual-chambered system and the chambers are separated by a proton exchange membrane (PEM) salt bridge using canteen wastewater. The process parameters including cathodic chamber aeration, nutrient dosage, nitrogen fluxing, stirring and anode geometry, were optimized. The potential difference (mV) and these systems' current (mA) performance have been analyzed. On the use of PANI-RGn carbon cloth as electrodes, the output voltage was found to be of the order of 180mV. The system developed herewith is highly cost-effective because of the use of graphene that has been generated from waste plastic through catalytic pyrolysis. Hence, the present study revealed that a potential green energy alternative is PANI-RGn in situ polymerized cotton fabric and circular aluminium-mesh electrode in anoxic MFC.
