Electrode catalyst for fuel cell and fuel cell using the same

2:

• An electrode catalyst for a fuel cell as claimed in claim 1, characterized in using as an electrode catalyst one which is obtained through carbonization processing by baking after having added a metal compound to a raw material for producing the graphitization-resistant carbon and mixed them, and which has the random layer structure at least in a part of the material structure.

3:

• An electrode catalyst for a fuel cell as claimed in claim 1, characterized in that said random layer structure is carbon nano-onion structure developed into onion-like lamination layers around metal particles.

4:

• An electrode catalyst for a fuel cell as claimed in claim 2, characterized in that the raw material for producing said graphitization-resistant carbon are to be selected from a group of the materials consisting of poly (furfuryl alcohol), furan resin or thermosetting resin including phenol resin, brown coal, cellulose, poly (vinylidene chloride) and lignin.

5:

• An electrode catalyst for a fuel cell as claimed in claim 2, characterized in that said metal compounds contain at least one of these metals of iron, cobalt, nickel, chromium, and manganese.

6:

• An electrode catalyst for a fuel cell as claimed in claim 2, characterized in that an amount of said metal compound to be added to the graphitization-resistant carbon is in the range of 0.5 to 15 wt % on the basis of the metal component(s) contained in said metal compounds.

7:

• An electrode catalyst for a fuel cell as claimed in claim 2, characterized in that said metal compound has one of the forms of nitrate, chloride, acetyl-acetate or acetyl-acetate complex, and metallocene and its derivatives.

8-12. (canceled)

13:
