摘要： A method of producing a H2 rich gas stream includes supplying an O2 rich gas, steam, and fuel to an inner reforming zone of a fuel processor that includes a partial oxidation catalyst and a steam reforming catalyst or a combined partial oxidation and stream reforming catalyst. The method also includes contacting the O2 rich gas, steam, and fuel with the partial oxidation catalyst and the steam reforming catalyst or the combined partial oxidation and stream reforming catalyst in the inner reforming zone to generate a hot reformate stream. The method still further includes cooling the hot reformate stream in a cooling zone to produce a cooled reformate stream. Additionally, the method includes removing sulfur-containing compounds from the cooled reformate stream by contacting the cooled reformate stream with a sulfur removal agent. The method still further includes contacting the cooled reformate stream with a catalyst that converts water and carbon monoxide to carbon dioxide and H2 in a water-gas-shift zone to produce a final reformate stream in the fuel processor.

摘要： A monolithic catalyst with micro-scale flow channels and methods of making such a monolithic catalyst are provided. The monolithic catalyst includes a plurality of thin catalyst walls. The walls have a set thickness in a range from 1 to 150 &mgr;m. The thin catalyst walls define a plurality of flow channels. A fugitive material is used to form the flow channels. The flow channels have a set width in a range from 1 to 200 &mgr;m. The flow channels are formed by an organic fugitive material, which burns off during processing. By using the thin catalyst walls and flow channels having a set width in a range from 1 to 200 &mgr;m, a reduced diffusion path length that molecules travel between the bulk gas and the active site is provided. Accelerating the mass transport thus improves the overall reaction rate, which allows processing of more reactants. Thus, the volume of the required catalyst is reduced, allowing more compact reactors. Fabrication methods involve simple, low-cost and scaleable procedures, allowing the flow channel and catalyst dimensions to be easily scaled to a requisite size for a given application. One fabrication method involves tape casting successive layers of fugitive and catalyst materials, and then firing to remove the organic binders and partially sinter the catalyst particles. The slurries can also be cast into thin layers using various processes, including screen printing, wet spraying and spin casting. Another fabrication method for fabricating a supported catalyst involves dipping a pre-shaped metal foil into a slurry containing an active catalyst powder, allowing the catalyst slurry to coat the foil evenly and allowing the catalyst slurry coated foil to dry. The catalyst slurry coated foil is dipped into a solution to form a fugitive coating layer, next the coated metal foil is cut into strips and formed into a selected shape.

摘要： An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

摘要： A propulsion system for a vehicle having pairs of front and rear wheels and a fuel tank. An electrically driven motor having an output shaft operatively connected to at least one of said pair of wheels is connected to a fuel cell having a positive electrode and a negative electrode separated by an electrolyte for producing dc power to operate the motor. A partial oxidation reformer is connected both to the fuel tank and to the fuel cell receives hydrogen-containing fuel from the fuel tank and water and air and for partially oxidizing and reforming the fuel with water and air in the presence of an oxidizing catalyst and a reforming catalyst to produce a hydrogen-containing gas. The hydrogen-containing gas is sent from the partial oxidation reformer to the fuel cell negative electrode while air is transported to the fuel cell positive electrode to produce dc power for operating the electric motor.
