Abstract
The oxygen reduction reaction has faster kinetics in anion exchange membrane fuel cell, opening the possibility of using nonprecious materials as electrocatalysts. Therefore, defective nitrogen-doped graphene foam is applied as an electrocatalyst in alkaline medium. The large surface area and highly porous structure results in high oxygen reduction reaction activity in rotating ring-disk electrode measurements. During potential cycling tests, the nitrogen-doped graphene foam displayed comparable durability to a Pt/CB catalyst.
