20120141907 | FUEL CELL MEMBRANE ELECTRODE ASSEMBLY - The fuel cell membrane electrode assembly includes PtRu active species supported on mesoporous carbon nitride materials for use in the anode of direct methanol fuel cells. The fuel cell membrane electrode assembly includes an anode plate, a gas diffusion layer, and a catalyst adjacent a PEM membrane. The composition of the catalyst is about 30 wt % active species and 70 wt % support materials. The nitrided PtRu on a mesoporous carbon support provides enhanced hydrogen adsorbing capacity to accelerate the rate of oxidation of methanol at the anode of a direct methanol fuel cell, resulting in greater efficiency of the fuel cell. | 06-07-2012 |
20130165318 | METHANOL ELECTRO-OXIDATION CATALYST AND METHOD OF MAKING THE SAME - The methanol electro-oxidation catalysts include nano-oxides of rare earth metals (i.e., cesium, praseodymium, neodymium and samarium) and platinum nano-particles. The nano-oxides of the rare earth metals are dispersed during synthesis of a support material, preferably formed from mesoporous carbon. The platinum nano-particles form between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, the rare earth metal forms between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, and carbon and oxygen forming the balance (between about 70 wt % and about 80 wt %) of the methanol electro-oxidation catalyst. | 06-27-2013 |
20130172174 | METHANOL ELECTRO-OXIDATION CATALYST AND METHOD OF MAKING THE SAME - The active methanol electro-oxidation catalysts include nano-oxides of transition metals (i.e., iron, cobalt and nickel) and platinum-ruthenium alloy nano-particles. The nano-oxides of the transition metals are dispersed during synthesis of a support material, such as mesoporous carbon. The catalyst includes a support material formed from mesoporous carbon, a nano-oxide of a transition metal dispersed in the support material, and platinum-ruthenium alloy nano-particles supported on the nano-oxide of the transition metal, the platinum-ruthenium alloy nano-particles (in a 1:1 molar ratio) forming about 15 wt % of the methanol electro-oxidation catalyst, the transition metals forming about 15 wt % of the methanol electro-oxidation catalyst, and carbon and oxygen forming the balance of about 70 wt % of the methanol electro-oxidation catalyst. | 07-04-2013 |
20130256123 | ELECTROCATALYST FOR ELECTROCHEMICAL CONVERSION OF CARBON DIOXIDE - An electrocatalyst for the electrochemical conversion of carbon dioxide to hydrocarbons is provided. The electrocatalyst for the electrochemical conversion of carbon dioxide includes copper material supported on carbon nanotubes. The copper material may be pure copper, copper and ruthenium, copper and iron, or copper and palladium supported on the carbon nanotubes. The electrocatalyst is prepared by dissolving copper nitrate trihydrate in deionized water to form a salt solution. Carbon nanotubes are then added to the salt solution to form a suspension, which is then heated. A urea solution is added to the suspension to form the electrocatalyst in solution. The electrocatalyst is then removed from the solution. In addition to dissolving the copper nitrate trihydrate in the deionized water, either iron nitrate monohydrate, ruthenium chloride or palladium chloride may also be dissolved in the deionized water to form the salt solution. | 10-03-2013 |
20130256124 | ELECTROCATALYST FOR ELECTROCHEMICAL CONVERSION OF CARBON DIOXIDE - The electrocatalyst for the electrochemical conversion of carbon dioxide includes a copper material supported on titania nanotubes. The copper material may be pure copper, copper and ruthenium, or copper and iron supported on the titania nanotubes. The electrocatalyst is prepared by first dissolving copper nitrate trihydrate in deionized water to form a salt solution. Titania nanotubes are then added to the salt solution to form a suspension, which is then heated. A urea solution is added to the suspension to form the electrocatalyst in solution. The electrocatalyst is then removed from the solution. In addition to dissolving the copper nitrate trihydrate in the volume of deionized water, either iron nitrate to monohydrate or ruthenium chloride may also be dissolved in the deionized water to form the salt solution. | 10-03-2013 |
