Beschreibung
Zusammenfassung:	The present invention relates to a method for preparing an alloy catalyst for a fuel cell. More specifically, the method is used to prepare the alloy catalyst by alloying platinum contained in a cathode carbon carrier catalyst with iridium in order to solve the problem regarding the corrosion of the cathode carbon carrier catalyst due to the fuel cell undergoing harsh conditions such as a driving operation of a vehicle. The present invention prepares the alloy catalyst through a predetermined process and under predetermined reaction conditions to reduce the settling time of the carbon surface charge and control the size of metal particles, thereby enabling uniform distribution of metal particles and excellent durability as well as providing high-quality products. 본 발명은 연료전지용 합금촉매의 제조방법에 관한 것으로서, 더욱 상세하게는 연료전지에 있어서 자동차의 운전 진행과 같은 가혹 조건에 따라 환원극 탄소 담지체 촉매가 부식되는 문제를 개선하기 위하여 환원극 탄소 담지체 촉매에 함유된 백금에 이리듐을 합금시킨 합금촉매를 제조하되 특정 공정과 반응 조건으로 제조함으로 인해 탄소 표면 전하의 안정화 시간을 단축할 수 있고 금속입자 크기를 제어하면서 금속입자 분포가 균일하고 내구성이 우수한 고품질의 제품을 제조할 수 있는 연료전지용 합금촉매의 제조방법에 관한 것이다.
