燃料电池用纳米催化剂的研究

Study on nano-catalyst for fuel cells

催化剂是燃料电池的最关键材料之一 ,从降低成本、减少资源消耗的角度出发 ,研制高分散度、纳米尺寸颗粒催化剂有重要意义。采用原位还原的新技术制备高分散度纳米催化剂用于质子交换膜燃料电池 ,并采用扫描电镜。

Catalyst as one of the key materials for fuel cells should be tremendously cut down its price to fit the requirement of fuel cell commercialization.The aim of this article was to prepare catalyst as nanometer particles highly dispersed on Valcan 72 carbon.The catalyst was uniformly localized on the surface and pores of carbon by reduction technique on site.It is of significance since low cost catalyst could be prepared by this new technique.SEM,TEM and specific surface area analysis methods were used to characterize the surface morphology and properties of the catalyst.
