A stable and active iron catalyst supported on graphene nano-flakes for the oxygen reduction reaction in polymer electrolyte membrane fuel cells

- Graphene nanoflakes with nitrogen were used as a support for catalytic sites.
- Iron was successfully adsorbed on the surface to create catalyst sites.
- The crystallinity properties and elemental surface composition was studied.
- The catalyst is stable for the oxygen reduction reaction on the cathode of a PEMFC.
