    摘要： 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 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.

    摘要： The present invention is a production process for an electrode catalyst for a fuel cell, which is characterized by comprising a step (I) of mixing a nitrogen-containing organic substance, a transition metal compound and conductive particles with a solvent and a step (II) of calcining a mixture obtained in the step (I). According to the production process for an electrode catalyst for a fuel cell of the present invention, an electrode catalyst for a fuel cell, which uses a transition metal and has smaller particle diameters and a higher catalytic activity than in a conventional production process, can be produced. Hence, the electrode catalyst for a fuel cell produced by the production process for an electrode catalyst for a fuel cell of the present invention has high reaction efficiency. Moreover, a catalyst layer for a fuel cell, which uses this electrode catalyst for a fuel cell, has a high catalytic ability, and therefore, a fuel cell having this catalyst layer for a fuel cell has very excellent power generation properties.
