ABSTRACT:
To provide an electrode catalyst for a fuel cell comprising inexpensive materials substituting for a precious metal catalyst such as platinum, and a fuel cell using the same. Poly (furfuryl alcohol) containing ferrocene is prepared by dissolving ferrocene corresponding to 1 to 3 wt % on the iron atomic basis in furfuryl alcohol, adding hydrochloric acid (2 mol/dm3) thereto as a polymerization initiator, and then polymerizing them in the air at 70° C. for 48 hours. Random layers2developed into onion-like lamination layers around iron particles are produced by heating this poly (furfuryl alcohol) up to 700° C. at a temperature rising rate of 150° C./h, and then holding the state for an hour to carbonize it. The iron carbon complex having this structure of the random layers2is applied especially to the cathode side as the electrode catalyst, to form the cells for the fuel cell.
