Summary: | The invention discloses a catalyst for a proton exchange membrane fuel cell. The catalyst comprises a carbon black carrier and a metal component loaded on the carbon black carrier, wherein the metal component comprises platinum and an auxiliary agent metal, the mass percentage content of platinum in the catalyst is 40-60%, the mass percentage content of the auxiliary agent metal is 2-6%, and the auxiliary agent metal is iron, cobalt, nickel or copper. Besides, the invention further provides a method for preparing the catalyst. The catalyst is stable in performance in an electrochemical performance test;, the carbon black carrier is obtained by mixing and ball-milling glycine and L-cysteine or beta-alanine and then performing high-temperature treatment, and the nitrogen element is doped into the carbon black carrier; metal components loaded on the surface of the catalyst are dispersed more uniformly, and the bonding strength of the metal components and the carbon black carrier is higher.
