A fuel cell catalyst containing platinum, zinc, and at least one of nickel and iron.

Fuel cell electrocatalyst of Pt-Zn-Ni/Fe

A composition for use as a catalyst in, for example, a fuel cell, the composition comprising platinum, copper, and nickel, wherein the concentration of platinum therein is greater than 50 atomic percent and less than 80 atomic percent, and further wherein the sum of the concentrations of platinum, copper and nickel is greater than 95 atomic percent.

Platinum-copper-nickel fuel cell catalyst

The present invention is directed to a composition for use as a catalyst in, for example, a fuel cell, the composition comprising platinum and copper, wherein the concentration of platinum is greater than 50 atomic percent and less than about 80 atomic percent, and further wherein the composition has a particle size which is less than 35 angstroms. The present invention is further directed to various methods for preparing such a composition.

Platinum-copper fuel cell catalyst

In one or more embodiments, the concentration of platinum is less than 50 atomic percent, and/or the concentration of chromium is less than 30 atomic percent, and/or the concentration of copper, nickel, or a combination thereof is at least 35 atomic percent.

Platinum-chromium-copper/nickel fuel cell catalyst

An improved metal alloy composition for a fuel cell catalyst containing platinum, manganese, and cobalt.

Fuel cell electrocatalyst of Pt-Mn-Co

A fuel cell catalyst comprising platinum, titanium and tungsten. In one or more embodiments, the concentration of platinum is less than 60 atomic percent, and/or the concentration of titanium is at least 20 atomic percent, and/or the concentration of tungsten is at least 25 atomic percent.

Platinum-titanium-tungsten fuel cell catalyst

The present invention is directed to a method for forming combinatorial libraries comprising arrays of materials prepared by depositing a metal species on a support for use as catalysts, such as electrocatalysts. The invention is also directed to combinatorial libraries comprising an array of such metal-containing supported catalysts. These catalyst-containing libraries are particularly well-suited for use in conducting combinatorial research investigations, in particular with respect to electrocatalysts for fuel cells.

Combinatorial methods for preparing electrocatalysts

Low dielectric materials and films comprising same have been identified for improved performance when used as performance materials, for example, in interlevel dielectrics integrated circuits as well as methods for making same. In one aspect of the present invention, the performance of the dielectric material may be improved by controlling the weight percentage of ethylene oxide groups in the at least one porogen.

Compositions for preparing low dielectric materials

A fuel cell electrocatalyst that contains platinum, indium, and at least one of tungsten, iron, and manganese.

Platinum-indium-iron/tungsten/manganese fuel cell electrocatalyst

A composition for use as a catalyst in, for example, a fuel cell, the composition comprising platinum, copper and tungsten, or an oxide, carbide and/or salt of one or more of platinum, copper and tungsten, wherein the sum of the concentrations of platinum, copper and tungsten, or an oxide, carbide and/or salt thereof, is greater than 90 atomic percent.

Platinum-copper-tungsten fuel cell catalyst

Low dielectric materials and films comprising same have been identified for improved performance when used as interlevel dielectrics in integrated circuits as well as methods for making same. These materials are characterized as having a dielectric constant (&#x3ba;) a dielectric constant of about 3.7 or less; a normalized wall elastic modulus (E'), derived in part from the dielectric constant of the material, of about 15 GPa or greater; and a metal impurity level of about 500 ppm or less. Low dielectric materials are also disclosed having a dielectric constant of less than about 1.95 and a normalized wall elastic modulus (E&#x2032;), derived in part from the dielectric constant of the material, of greater than about 26 GPa.

Low dielectric materials and methods for making same

A method for forming a supported metal-containing powder. The method comprises forming a dispersion of a particulate support in a solution, which comprises a solvent and a dissolved metal. Heat is removed from the dispersion to precipitate the dissolved metal from the solution onto the particulate support. Preferably, enough heat is removed to freeze the solution. Also, the heat is removed is preferably removed from the dispersion by contacting a container containing the dispersion with a cryogenic liquid. After precipitating the dissolved metal onto the particulate support, the particulate support is separated from the solution, preferably by freeze-drying, to yield the supported metal-containing powder, which comprises the particulate support and a precipitated metal thereon.
