Mesoporous carbon for polymer electrolyte fuel cell electrodes

Abstract

This article features the importance of mesoporous carbon as a constituent in the gas diffusion layer for easy reactant permeation and water removal in polymer electrolyte fuel cells. The utility of mesoporous carbon as catalyst support to enhance Pt utilization is also crucial in order to reduce Pt usage to meet both cost and Pt availability constraints. We attempt to provide an overview of the strategy and benefit of using mesoporous carbon to meet the specific requirements of emerging technological applications, such as fuel cells.
