Abstract:
    The preparation method for electric catalyst of fuel cell comprises: selecting 3-50nm nano Ni as core and thin Pt or PtRu as shell, wherein the rate between Ni and Pt or PtRu is 10:10~100; selecting the load capacity of Pt or PtRu on C carrier as 10-60%; preparing the glycol solution of NiSO4, NiCl2 or Ni(NO3)2; adding C carrier and N2H4, adjusting pH value by KOH or NaOH; adding glycol solution of HPtCl6 or mixture of HPtCl6 and RuCl3; adjusting pH value; separating, cleaning, and drying. This invention can improve noble metal utility and reduces cell cost.
