CATALYST FOR FUEL CELL, FUEL CELL COMPRISING THE SAME AND MANUFACTURING METHOD THEREOF

The present disclosure relates to a catalyst for a fuel cell, a fuel cell including the same and a method for preparing the catalyst for a fuel cell. More specifically, the catalyst for a fuel cell according to the present disclosure can exhibit superior catalytic activity as compared to the existing catalyst even when the catalyst metal is used at a very low content because some metal of the metal nanoparticles distributed on a carbon support is replaced with catalyst metal single atoms.
