Abstract: Disclosed is a method for producing a core-shell structured electrocatalyst for a fuel cell. The method includes uniformly supporting nano-sized core particles on a support to obtain a core support, and selectively forming a shell layer only on the surface of the core particles of the core support. According to the method, the core and the shell layer can be formed without the need for a post-treatment process, such as chemical treatment and heat treatment. Further disclosed is a core-shell structured electrocatalyst for a fuel cell produced by the method. The core-shell structured electrocatalyst has a large amount of supported catalyst and exhibits superior catalytic activity and excellent electrochemical properties. Further disclosed is a fuel cell including the core-shell structured electrocatalyst.
