Electrode catalyst for fuel cell and fuel cell using the same

摘要

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 layers 2 developed 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 layers 2 is applied especially to the cathode side as the electrode catalyst, to form the cells for the fuel cell.
