NOVELTY - The method comprises forming a catalyst slurry by mixing catalysts, an ionomer binder and a solvent, separating the catalysts and the ionomer binder by rotating the catalyst slurry to apply centrifugal force, evaporating the solvent in the catalyst slurry, which is separated state the catalyst and the ionomer binder, to form as solid state, and drying the catalyst slurry, where the catalysts and the ionomer binder are distributed in the catalyst layer in a separated manner. The densities of the catalysts and the ionomer binder are different from each other in the catalyst layer.    USE - The method is useful for manufacturing a catalyst layer of membrane electrode assembly for a fuel cell.    ADVANTAGE - The method enables uniform distribution of the ionomer binder and the catalyst throughout the catalyst layer thus easily transferring the hydrogen gas through the catalyst layer interface and passing the hydrogen ion through the ion exchange layer interface in a considerably smooth manner thus improving the performance of the membrane electrode assembly.    DETAILED DESCRIPTION - The method comprises forming a catalyst slurry by mixing catalysts, an ionomer binder and a solvent, separating the catalysts and the ionomer binder by rotating the catalyst slurry to apply centrifugal force, evaporating the solvent in the catalyst slurry, which is separated state the catalyst and the ionomer binder, to form as solid state, and drying the catalyst slurry, where the catalysts and the ionomer binder are distributed in the catalyst layer in a separated manner. The densities of the catalysts and the ionomer binder are different from each other in the catalyst layer of the membrane electrode assembly. The catalyst slurry includes 20-25 wt.% of a mixture of the catalyst and the ionomer binder, and 75-80 wt.% of the solvent. The catalyst slurry is dried at a temperature of 80-120 degrees C for 6-8 hours.
