Prolonged Stability of Air-Cathode Microbial Fuel Cell Performance by Inhibiting Aerobic Microbial Growth Using Platinum and Carbon Nanotube (PT-CNT) Nanoparticles as a Cathode Catalyst

The inescapable growth of heterotrophic aerobic bacteria on the surface of air cathodes is an important factor causing oxygen depletion and substrate loss thus reduce the performance stability of air cathode single-chamber microbial fuel cells (MFCs). In this study, the possible use of platinum and...
