Synthesis, Studing and Performance Comparing of Membrane Electrode Assembly Fabricated by Pt/N-rGO with Pt/Vulcane

Proton exchange membrane fuel cells (PEMFCs) are one of the most promising clean energy conversion devices due to their high conversion efficiency, low/zero emission, and high power/energy densities. Nitrogen doping has been an effective way to tailor the properties of graphene and render its potential use for various applications. We developed a simple chemical method to obtain bulk quantities of N-doped, reduced grapheme oxide (GO) powder through thermal annealing of GO in ammonia and hydrazine. Oxygen reduction and nitrogen doping were achieved simultaneously under the hydrothermal reaction. Electrochemical measurements and MEA performance show that the nitrogen doped graphene support has the better activity than Vulcan.
