Preparation and Characteristic of New Type Nano Rare Earth Electrocatalyst for PEMFC
质子交换膜燃料电池(PEMFC)新型纳米稀土催化剂的制备与性质

Nano rare earth alloy was prepared by a supersonic co-precipitation and low temprature reduction synthesis method. The research of XRD, SEM, TEM indicates that the particle size of the sample powder is about 20nm, and the test results by PEMFC electrochemistry workstation show that the sample powder modified by Pt has good electrocatalytic activity due to its good hydrogen transfer power.
