Abstract
The University of Central Florida invention is a design strategy for discovering new materials and catalysts for energy conversion. The method seeks to regulate the local bonding and local coordination environment (LCE) of the classic metal-nitrogen-carbon (M-N-C) catalysts by infusing fluorine (F)-coordination. As a result, the rationally designed catalyst shows a maximum power density of 0.57 W cm-2 and more than 5,900 hours of operation in direct ethanol fuel cells, outperforming benchmarking catalysts. The tactic of F-induced LCE regulation can be applied to other catalysts with drastically improved activities and stabilities.
