摘要Platnium particles system supported by carbon black are the most commonly used polymer electrolyte membrane fuel cells (PEMFCs) catalysts for cathodic oxygen reduction. Nevertheless, the approaching commercialization of polymer electrolyte membrane fuel cells (PEMFCs) is still hindered by the high cost and limited operational stability of the Pt-based cathode catalysts traditionally utilized.Specifically, the cathode catalyst layer comprises over half of the overall cost of a PEMFC stack and the increa-sing demands for fuel cell power systems will undoubtedly drive up the already high price of Pt. Developing new catalyst with reduced Pt dependency, improved oxygen reduction reaction (ORR) activity and high stability is an urgent necessity.The emerging novel carbon nanomaterials supported systems are promised solutions. More and more studies prove that, based on the carbon nanomaterials supported platinum system, the utilization rate of platinum is improved, the necessary mass loading of platinum is reduced, catalytic activity and stability of the catalyst are enhanced. Furthermore, the cost performances of the catalyst are enhanced efficiently. Therefore, this paper summarized the recent studies on carbon nanomaterials based catalysts with discussing their existing problems and future development directions for boosting the large scale commercialization of the PEMFCs. © 2017, Materials Review Magazine.
