    • A process for regenerating a selective oxidizer bed, by the introduction of oxygen is provided. In a single oxidizer bed environment, regeneration may be carried out on shut-down or on start-up. On start-up, the process includes providing a selective oxidizer bed as well a fuel processor. The selective oxidizer bed is heated to approximately 180° F. Air is passed through the selective oxidizer bed while maintaining the selective oxidizer bed at a temperature of approximately 180° F. for 1-2 minutes. The selective oxidizer is then purged with steam to remove residual air therefrom. Fuel is then introduced from the fuel processor into the selective oxidizer. On shut-down, residual fuel is purged from the oxidizer bed and then air is passed therethrough while maintaining the bed at a temperature between approximately 180° F. to approximately 220° F. The oxidizer is allowed to cool to ambient temperature and then heated to 180° F. Residual air is then purged from the oxidizer for subsequent introduction of fuel. Multiple oxidizer beds may be provided in parallel to one another to enable continuous, uninterrupted operation with bed remaining operation at all times while the other is being regenerated. Regeneration may also be carried out by thermal cycling of the selective oxidizer bed.

    • A fuel gas reformer assemblage for use in a fuel cell power plant is formed from a composite plate assembly which includes spaced-apart divider plates with columns of individual gas passages. The reformer assemblage is constructed from a series of repeating sub-assemblies, each of which includes a core of separate regenerator/heat exchanger gas passages. The core in each sub-assembly is sandwiched between a pair of reformer gas passage skins, which complete the assembly. Adjacent reformer gas/regenerator/reformer gas passage sub-assemblies in the composite plate assembly are separated from each other by burner gas passages. The regenerator/heat exchanger gas passages and the reformer gas passages in each sub-assembly are connected by gas flow reversing manifolds which form a part of each sub-assembly. The fuel gases flow in one end of the assemblage, through the reformer gas passages, and then reverse their direction of flow in the return manifolds so as to exit the reformer assemblage through the regenerator gas flow passages. The burner gases flow in one end of the reformer assemblage and out the other end. The walls of the burner and reformer gas flow passages are selectively catalyzed after the assemblage has been constructed.

    • A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply which is used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like; or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, thiophenes and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the now desulfurized hydrocarbon fuel supply continues through the remainder of the fuel processing system. The method involves adding hydrogen to the fuel stream prior to the desulfurizing step. The method can be used to desulfurize either a liquid or a gaseous fuel stream. The addition of hydrogen serves to extend the useful life of the nickel reactant. The hydrogen can be derived from source of pure hydrogen gas, a recycle gas stream, or can be derived from an electrolysis cell which breaks down water produced in the fuel cell into its hydrogen and oxygen components. The hydrogen when added to the fuel stock serves to prevent or minimize carbon formation on the nickel reactant bed, thereby extending the useful life of the reactant bed, since carbon deposits tend to block active sites in the reactant bed.
    • 燃料处理方法可操作以基本上除去用于在诸如汽车,公共汽车,卡车,船等的移动环境中为燃料电池发电厂供电的未稀释的烃燃料原料供应中存在的所有硫 ; 或在静止的环境中。 电厂氢燃料源可以是汽油,柴油燃料或含有相对高水平的有机硫化合物如硫醇,硫化物,二硫化物,噻吩等的类似燃料。 未稀释的碳氢化合物燃料供应通过镍反应物脱硫器床,其中有机硫化合物中基本上所有的硫与镍反应物反应,并转化为硫化镍,而现在脱硫的碳氢化合物燃料供应继续通过其余的 燃料加工系统。 该方法包括在脱硫步骤之前向燃料流中加入氢气。 该方法可用于对液体或气态燃料流进行脱硫。 氢的添加用于延长镍反应物的使用寿命。 氢气可以源自纯氢气,循环气流,或者可以从将燃料电池中产生的水分解成其氢和氧组分的电解池中得到。 加入燃料油中的氢气用于防止或最小化镍反应物床上的碳,从而延长反应物床的使用寿命,因为碳沉积物倾向于阻挡反应物床中的活性位点。

    • A fuel gas reformer assemblage for use in a fuel cell power plant is formed from a composite plate assembly which includes spaced-apart divider plates with interposed monolithic open cell sponge-like members which form gas passages. The monolithic members have a lattice of internal open cells which are both laterally and longitudinally interconnected so as to provide for a diffuse gas flow. The entire surface area of the monolithic components is wash coated with a porous alumina layer, and selected areas of the wash coat are also catalyzed. The reformer assemblage is constructed from a series of repeating sub-assemblies, each of which includes a core of separate regenerator/heat exchanger gas passages. The core in each sub-assembly is sandwiched between a pair of reformer gas passage skins, which complete the subassembly. Adjacent reformer gas/regenerator/reformer gas passage sub-assemblies in the composite plate assembly are separated from each other by burner gas passages.
