摘　　要：采用微波法、回流法,通过自还原的方式制备了质子交换膜燃料电池(PEMFC)用的Pt_3Fe/MWCNTs催化电极。利用X射线衍射光谱(XRD)和扫描电子显微镜(SEM)对催化剂的微观结构和形貌进行了表征。采用循环伏安(CV)和线性扫描伏安法(LSV)对其电化学性能进行了测试。结果表明,采用采用微波法、回流法,通过自还原的方式制备制得的质子交换膜燃料电池Pt_3Fe/MWCNTs催化剂的颗粒粒径细小、分散性好,催化活性高,稳定性好,为制备Pt_3Fe MWCNTs催化剂工业化进程打好了基础。Pt3Fe/MWCNTs catalytic electrode for proton exchange membrane fuel cell （PEMFC） was prepared bymicrowave reduction and refluxing. The microstructure and morphology of the catalysts were characterized by X raydiffraction （XRD） and scanning electron microscopy （SEM）. The electrochemical performance was tested by cyclicvoltammetry （CV） and linear scanning voltammetry （LSV）. The results showed that by using microwave method andreflux method, membrane fuel cell Pt3 Fe/MWCNTs catalyst by proton self reduction methods preparation prepared byexchange of particles had good dispersion, high catalytic activity and good stability, laid the foundation for the preparationof Pt3Fe/MWCNTs catalyst industrialization.
