Abstract: A method and catalysts and fuel processing apparatus for producing a hydrogen-rich gas, such as a hydrogen-rich syngas are disclosed. According to the method, a CO-containing gas, such as a syngas, contacts a platinum-free ruthenium-cobalt water gas shift (“WGS”) catalyst, in the presence of water and preferably at a temperature of less than about 450° C., to produce a hydrogen-rich gas, such as a hydrogen-rich syngas. Also disclosed is a platinum-free ruthenium-cobalt water gas shift catalyst formulated from: a) Ru, its oxides or mixtures thereof, b) Co, Mo, their oxides or mixtures thereof, and c) at least one of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La, Ce, Eu, their oxides and mixtures thereof. The WGS catalyst may be supported on a carrier, such as any one member or a combination of alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, zeolite, perovskite, silica clay, yttria and iron oxide. Fuel processors containing such water gas shift catalysts are also disclosed.

Abstract: The present teachings are directed toward electrocatalyst compositions of alloys of platinum, tungsten and one of either of nickel or zirconium for use in fuel cells. The alloys consists essentially of platinum present in an atomic percentage ranging between about 20 percent and about 45 percent, tungsten present in an atomic percentage ranging between about 30 percent and about 70 percent, and one of either nickel present in an atomic percentage ranging between about 5 percent and about 25 percent, or zirconium present in an atomic percentage ranging between about 5 percent and about 40 percent.

Abstract: The present teachings are directed toward compositions of supercapacitor electrode materials containing a functionalized carbon nanotube-containing material substantially free of binder material and methods for preparing the functionalized carbon nanotube-containing material.
