摘要
Provided are a method of preparing an electrocatalyst for fuel cells in a core-shell structure, an electrocatalyst for fuel cells having a core-shell structure, and a fuel cell including the electrocatalyst for fuel cells. The method may be useful in forming a core and a shell layer without performing a subsequent process such as chemical treatment or heat treatment and forming a core support in which core particles having a nanosize diameter are homogeneously supported, followed by selectively forming shell layers on surfaces of the core particles in the support. Also, the electrocatalyst for fuel cells has a high catalyst-supporting amount and excellent catalyst activity and electrochemical property.
