| Fuel cell(FC) as a highly efficient,non-pollution energy conversion device,has attracted much attention.The cathode oxygen reduction reaction(ORR) is one of the most important and critical factors for performance of the battery,and restrict the commercialization.Therefore,it is important to develop a high efficiency electrocatalyst for the ORR and the mechanism of oxygen reduction for the development and commercialization of FC.In this paper,research progresses of the ORR mechanism on metal-based electrocatalysts,have been systematically reviewed on the base of a brief introduction of the FC.The materials include the ptelectrocatalyst,Pt-M electrocatalyst and heteroatom-doped carbon supported metal electrocatalysts.The effort to improve the catalytic activity and durability of the electrocatalysts have been summarized.Reseach on decrease the cost of electrocatalysts and novel non-precious metal electrocatalysts are also reported.The urgent problems and future research focuses on these non-precious metal oxygen reduction electrocatalysts have pointed out. |
