摘要： A fuel gas reformer assembly for use in a fuel cell power plant includes fuel gas passages, some of which contain a particulate alumina packing in which a vaporized steam-hydrocarbon fuel stream mixture is heated. The walls of the fuel gas passages are provided with an alumina coating which protects the walls of the passages from corrosion. The alumina coating of the walls, and alumina packing are both overlain by an alkaline earth metal oxide layer, such as a calcium oxide layer, that acts to limit carbon build-up on the surfaces of the coated passage walls. Limiting of carbon build-up in the reformer passages prevents premature clogging of the passages. The carbon build-up-limiting layer is formed on components of the reformer passages by applying a water-based slurry of alkaline earth metal compounds to the reformer passage surfaces, and then drying the slurry so as to solidify it. The formation of the desired crystalline phase of the coating occurs in situ on the coated passage surfaces during initial operation of the reformer. The coated packing material is operative to convert any free carbon remaining in the gas stream to carbon dioxide, or carbon monoxide, thereby further limiting carbon deposition in the assembly.

摘要： A fuel cell system includes a fuel cell ( 1 ) having a water passage and passage for gas required for power generation, a first protection device ( 5, 10 ) which prevents freezing of water in the fuel cell by maintaining the temperature of the fuel cell ( 1 ), and a second protection device ( 11, 12 ) which prevents freezing of water in the fuel cell by discharging the water in the fuel cell ( 1 ). A controller ( 50 ) selects one of the first protection device ( 5, 10 ) and the second protection device ( 11, 12 ) as the protection device to be used when the fuel cell ( 1 ) has stopped, and the fuel cell ( 1 ) is protected from freezing of water by operating the selected protection device.

摘要： A fuel gas processing system is operable to remove substantially all of the sulfur present in a hydrocarbon fuel supply used to power a fuel cell power plant in a mobile vehicular environment. The power plant fuel can be gasoline, diesel fuel, kerosene, fuel oil, natural gas, or another fuel which contains relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds react with the nickel reactant, and are converted to nickel sulfide while the desulfurized fuel continues through the remainder of the fuel processing system. The fuel cell power plant and the processing system can be used to power a mobile vehicle, such an automobile, truck, bus, or the like. An auxiliary supply of hydrogen is provided in order to power the fuel cell power plant during start up of the fuel processing system. A second auxiliary supply of desulfurized fuel is also provided to operate the fuel cell power plant during an interim period until the highest temperature component of the fuel processing system is brought up to operational temperatures during the start up protocol.

摘要： A fuel gas catalyst bed for use in a fuel cell power plant is formed from a monolithic open cell foam component, the open cell lattice of which forms gas passages through the catalyst bed. The monolithic component has a lattice of internal open cells which are both laterally and longitudinally interconnected so as to produce a diffuse gas flow pattern through the catalyst bed. All areas of the monolithic component which form the gas flow pattern are provided with an underlying high porosity wash coat layer. The porous surface of the wash coat layer is provided with a nickel catalyst layer, or a noble metal catalyst layer, such as platinum, rhodium, palladium, or the like, over which the gas stream being treated flows. The base foam lattice can be a metal such as aluminum, stainless steel, a steel-aluminum alloy, a nickel alloy, a ceramic, or the like material which can be wash coated. The use of an open cell lattice as the basis of a catalyst bed enables the formation of very compact, light weight and high surface area catalyst bed with excellent gas flow-through characteristics.
