Marchetti, G A; Loewe, W R

An improved fuel cell electrode and method for construction is disclosed wherein the electrodes are formed from adjacent layers of a porous substrate material such as carbon, and C[sub 60] carbon molecules or fullerenes. The C[sub 60] carbon molecules are arranged in face centered cubes and bind platinum atoms interspaced in the interstices of the cubes and on the C[sub 60] molecules to form a Pt/C[sub 60] layer. Lattices of platinum atoms are anchored to the individual platinum atoms of the Pt/C[sub 60] molecular layer to form a catalyst layer only several molecules thick. The resulting platinum atoms of the catalyst layer have a much greater surface area in contact with the electrolyte due to the chaotic surface area of the catalyst layer. The platinum atoms of that layer act as a catalyst for the fuel cell reaction. 4 figs.
