Abstract

Disclosed are a catalyst, a method for producing the catalyst, an electrode comprising the catalyst, a membrane-electrode assembly comprising the electrode, and a fuel cell comprising the membrane-electrode assembly, the catalyst having superb catalytic activity that can be obtained by means of a simple post-treatment process of the raw catalyst. The catalyst according to the present invention comprises a support, and metal particles supported therein, wherein the metal particles comprise main particles and an additional metal layer thereon, and the main particles and additional metal layer comprise the same metal elements. The metal particles have a budding structure or a rod structure by having just a particular latticed active surface of the main particles grow to form the additional metal layer, or a core-shell structure by having the entire latticed active surface of the main particles grow to form the additional metal layer.
