Abstract: This invention relates to carbon materials, such as a fullerene molecule or a curved carbon nanostructure, that are functionalized by addition chemistry performed on surface C—C double bond.

Abstract: Methanol tolerant catalyst material containing membrane electrode assemblies and fuel cells prepared therewith are provided. A substrate is coated with an electrocatalyst coating composition that includes a methanol tolerant catalyst obtained by mixing together: (1) organometallic clusters containing (i) a carbonyl group or a cyclic unsaturated hydrocarbon ligand group, and (ii) a chalcogen containing group selected from MnFepXm, MnXm, MnClpXm, or mixtures thereof wherein M=Pt, Ru or Re, X=S, Se or Te, and m, n and p=1 or 2, (2) an electrically conductive component, and (3) an organic solvent, such that the clusters are adsorbed on the electrically conductive component; subsequently removing the solvent; and in a non-oxidizing atmosphere, heat-treating of the clusters adsorbed on the electrically conductive component at a temperature of at least 175° C.

Abstract: Compositions containing functionalized carbon materials and their use, for example, as films for membranes or in other fabricated forms in electrode assemblies for electrochemical cells and fuel cells such as fuel cells are described.
