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

A fuel cell catalyst comprising platinum, chromium, and copper, nickel or a combination thereof. 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

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

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.
