Electrochemical cell electrode

An electrode for an electrochemical cell comprising a current collector, a mixture of a water-repellent binder and a support material having adsorbed thereon a transition metal or noble metal catalyst comprising a transition or noble metal salt and a polymer selected from the group consisting of poly (4-vinylpyridine), poly (2-vinylpyridine), poly (ethyleneimine), and poly (4-aminostyrene) wherein said electrode is prepared by the process comprising treating said support material with a solvent solution of a mixture of a transition metal or noble metal salt and said polymer, removing said solvent, and heating said mixture under an inert atmosphere at a temperature of about 500 to about 700 degrees centrigrade.

An electrochemical cell comprising electrodes consisting of an anodic electrode, a cathodic electrode, and an electrolyte and at least one of said electrodes comprising a current collector combined with a layer of a mixture of a binder and a transition metal or noble metal catalyst on a support material, said catalyst comprising a residue remaining after heating at about 500 to about 700 degrees centigrade of a mixture of a transition or noble metal salt, a polymer selected from the group consisting of poly (4-vinylpyridine), poly (2-vinylpyridine), poly (ethyleneimine), and poly (4-aminostyrene).
