Pt can be used as catalyst for most of the low-temperature fuel cell, but due to the limited storage capacity of the global pt, therefore, improving pt catalytic efficiency has a crucial significance. (1) Dendrimer encapsulated pt can better control the metal nanoparticle size, better improve the metallic catalytic activity and the ability of the deposition of metal; (2) Pamam is more conducive for pt to disperse and load on carbon; (3) Improving the catalytic efficiency of the carbon as a carrier of the catalyst, the catalyst utilization rate and stability of the catalyst.
