Beschreibung
Zusammenfassung:	The present invention relates to a catalyst for a fuel cell electrode, a membrane-electrode assembly for a fuel cell, a fuel cell, and a method for manufacturing the same. More particularly, the present invention relates to a catalyst for a fuel cell electrode comprises: a carbon spheres cluster in which a plurality of carbon spheres are connected; and an active metal supported on the carbon spheres cluster, and to a membrane-electrode assembly for a fuel cell, a fuel cell, and a method for manufacturing the same. The present invention can provide a catalyst for a fuel cell capable of enhancing the utilization of the catalyst and capable of excellent water management and excellent gas diffusion during high current operation. 본 발명은, 연료전지 전극용 촉매, 연료전지용 막-전극 접합체, 연료 전지 및 이의 제조방법에 관한 것으로, 복수 개의 탄소구 입자가 연결된 탄소구 클러스터(carbon spheres cluster); 및 상기 탄소구 클러스터 상에 담지된 활성 금속; 을 포함하는, 연료전지 전극용 촉매, 연료전지용 막-전극 접합체, 연료 전지 및 이의 제조방법에 관한 것이다.
