Abstract | Fuel cells that convert fuels into electricity with zero emission are the most environment-friendly devices for the future. This chapter explains the working principle of polymer electrolyte membrane (PEM) fuel cell. It consists of two electrodes: a cathode, where oxygen reduction reaction (ORR) occurs, and an anode for fuel (methanol or hydrogen) oxidation, separated by a polymer membrane. ORR is a multistep reaction that proceeds either through an efficient four electron process or via a two-step, two-electron pathway. The chapter demonstrates graphene-based, metal-free catalysts to show exceptional stability and high efficiency in fuel cells. Graphene is a vast carpet of the aromatic framework with tremendous opportunities for surface design. Heteroatom-doped graphene materials are a promising class of metal-free electrocatalysts for the ORR in fuel cell. Nitrogen-doped graphene has received significant interest in the recent years for applications including photocatalysis and ORR. |
