    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.
