A catalyst for a fuel cell including a carrier and an active metal dispersion that is supported in the carrier is disclosed. The catalyst may have a dispersity (Dp) represented by General Formula 1 and that ranges from between about 0.01 to about 1.0. Dispersity(Dp)={X−X10/(X1−B)}*(B/X)2 [General Formula 1] In the General Formula 1, X, X10, X1, and B are defined the same as described in the specification. A membrane-electrode assembly, and a fuel cell system having the catalyst are also disclosed.
