Abstract: 본발명은인 및붕소를함유하는코발트-인, 코발트-붕소촉매및 이의제조방법에관한것이다. 보다상세하게는알칼리연료전지(AFC) 음극용알칼리용액내에서수소산화반응(HOR) 시높은촉매효율을가지는인이첨가된코발트-인(Co-P) 및코발트-붕소(Co-B) 음극촉매를전기도금및 무전해도금방법으로제조하는데 있다. 본발명의코발트-인, 코발트-붕소음극촉매는기존의니켈및 그합금촉매보다훨씬높은수소산화반응속도를나타낸다. 본발명은알칼리연료전지음극수소산화반응에높은촉매활성도를가지는재료로저가이고수소산화반응성능이매우높이므로귀금속촉매(백금) 및니켈촉매를대체할수 있고, 공정이간편하여상용가능성이높다.

Abstract: The present invention relates to a cobalt-phosphorus (Co-P), cobalt-boron (Co-B) catalyst containing phosphorous and boron and a method for producing the same. More specifically, a Co-P and Co-B anode catalyst containing phosphorous having high catalyst efficiency during a hydrogen oxidation reaction (HOR) in an alkali solution for an anode of an alkali fuel cell (AFC) is produced through electro plating and electroless plating techniques. The Co-P and Co-B anode catalyst of the present invention exhibits a much faster hydrogenation speed than an existing nickel and alloy catalyst. The Co-P and Co-B catalyst of the present invention is a material having high catalyst activity in an HOR of an anode of an AFC. The cost is low and the HOR is highly effective so that the Co-P and Co-B catalyst can replace precious metal catalysts (platinum) and nickel catalysts. Processes are simple, making commercialization of the Co-P and Co-B catalyst highly possible.
Abstract translation: 本发明涉及含有磷和硼的钴 - 磷（Co-P），钴 - 硼（Co-B）催化剂及其制备方法。 更具体地说，在碱性燃料电池（AFC）的阳极用碱溶液中的氢氧化反应（HOR）中含有具有高催化剂效率的磷的Co-P和Co-B阳极催化剂通过电镀和无电镀 技术。 本发明的Co-P和Co-B阳极催化剂显示比现有的镍和合金催化剂快得多的氢化速度。 本发明的Co-P和Co-B催化剂是在AFC的阳极的HOR中具有高催化剂活性的材料。 成本低，HOR高效，Co-P和Co-B催化剂可代替贵金属催化剂（铂）和镍催化剂。 工艺简单，使Co-P和Co-B催化剂的商业化成为可能。
