The invention provides a fuel-
cell catalyst with a non-
platinum core-shell structure and a preparation method of the fuel-
cell catalyst, and relates to a fuel-
cell catalyst. A carrier of the catalyst is
activated carbon, the
active ingredient of the carrier is Fe-coated Pd, the
molar ratio of nanocrystalline iron of the
active ingredient Fe-coated Pd to
palladium of the
active ingredient Fe-coated Pd is 5:1, and the active ingredient Fe-coated Pd accounts for 40%-50% of the total
mass of the fuel-cell catalyst with the non-
platinum core-shell structure. The preparation method comprises the followings steps of: dissolving the
activated carbon into water; performing ultrasonic treatment on the mixture; leading
shielding gas in the mixture; adding reducing agents in the mixture; then adding a
ferric salt
aqueous solution in the mixture; reacting and then adding a
palladium chloride aqueous solution in the mixture to perform replacement reaction; and filtering, washing and
drying the mixture after the replacement reaction so as to obtain a product. The electrocatalytic activity of the catalyst is 10.63 times that of the traditional carbon load
palladium nanocrystal Pd / C catalyst, and is 23.05 times that of a commercial Pt / C catalyst. The cost is low, the preparation method is simple and practicable, the particle size of the catalyst is easy to control, and the fuel-cell catalyst is suitable for large-scale industrial production.
