A fuel cell electrode catalyst is provided which includes, at least, M1 that is at least one element selected from 3 to 7 group transition metal elements; M2 that is at least one element selected from iron group elements; M3 that is at least one element selected from 13 group elements; carbon; nitrogen; and oxygen, as constitutional elements, wherein when the atomic ratios of the elements (M1: M2: M3: carbon: nitrogen: oxygen) are represented by a:b:c:x:y:z, 0<a<1, 0<b≤0.5, 0<c<1, 0<x≤6, 0<y≤2, 0<z≤3 and a+b+c=1, and BET specific surface area is 100 m 2 /g or more. The fuel cell electrode catalyst has higher catalyst activity than conventional noble metal alternative catalysts, and is producible at low cost. The process for producing said catalyst can provide a fuel cell electrode catalyst with higher catalyst activity including a 13 group element and a transition metal such as titanium without high-temperature thermal treatment (calcining) step. |
