Beschreibung
Zusammenfassung:	The present invention relates to an oxidation catalyst for a fuel cell, a production method thereof, and a fuel cell comprising the oxidation catalyst. The irreversibly adsorbed oxidation catalyst for a fuel cell comprises: a carbon-based support; a gold (Au) nanocore supported on the carbon-based support; and a shell where a platinum (Pt) and an oxidation rate promoting element are irreversibly adsorbed on the gold nanocore. The oxidation catalyst for a fuel cell prevents the generation of catalyst poisons, promotes an oxidation reaction of a direct path, and has excellent catalyst efficiency, thereby implementing an effect of reducing the using amount of the platinum. 본 발명의 일 구현예는 탄소계 담체; 상기 탄소계 담체에 담지된 금(Au) 나노 코어; 및 상기 금 나노 코어 상에 백금(Pt) 및 산화속도촉진 원소가 비가역 흡착된 쉘; 을 포함하는 비가역 흡착된 연료전지용 산화촉매에 관한 것이다. 이러한 연료전지용 산화촉매는 촉매독의 생성을 방지하고, 직접경로의 산화반응을 촉진하며 촉매의 효율이 우수하여 백금의 사용량을 저감하는 효과를 구현한다.
