Beschreibung
Zusammenfassung:	The present invention relates to an irreversible adsorption catalyst for a fuel cell, which includes: a carbon-based carrier; a platinum (Pt) nanocore supported on the carbon-based carrier; and a shell irreversibly adsorbing an oxidation rate promoting element on the Pt nanocore. Accordingly, the present invention can provide: the irreversible adsorption catalyst for fuel cells, which can prevent the formation of catalyst poisons, accelerate an oxidation reaction of a direct path, and can reduce the amount of Pt with excellent efficiency of the catalyst; a production method capable of mass-producing the irreversible adsorption catalyst with excellent efficiency of the catalyst; and a fuel cell including the irreversible adsorption catalyst in a low content and maximizing the battery performance. 본 발명은 탄소계 담체; 상기 탄소계 담체에 담지된 백금(Pt) 나노 코어; 및 상기 백금 나노 코어 상에 산화속도촉진 원소가 비가역 흡착된 쉘; 을 포함하는 연료전지용 비가역 흡착 촉매에 관한 것이다. 이를 통해, 본 발명은 촉매독의 생성을 방지하고, 직접경로의 산화반응을 촉진하며, 촉매의 효율이 우수하여 백금의 사용량을 저감할 수 있는 연료전지용 비가역 흡착 촉매, 상기 비가역 흡착 촉매를 우수한 효율성으로 대량생산할 수 있는 제조방법 및 상기 비가역 흡착 촉매를 낮은 함량으로 포함하면서도 전지 성능이 극대화된 연료전지를 제공할 수 있다.
