    摘要： A reformer system (11) having a hydrodesulfurizer (12) provides desulfurized natural gas feedstock to a catalytic steam reformer (16), the outflow of which is treated by a water gas shift reactor (20) and optionally a preferential CO oxidizer (58) to provide reformate gas (28, 28a) having high hydrogen and moderate carbon dioxide content. To avoid damage to the hydrodesulfurizer from overheating, any deleterious hydrogen reactants, such as the oxygen in peak shave gas or olefins, in the non-desulfurized natural gas feedstock (35) are reacted (38) with hydrogen (28, 28a; 71) to convert them to alkanes (e.g., ethylene and propylene to ethane and propane) and to convert oxygen to water in a catalytic reactor (38) cooled (46), below a temperature which would damage the reactor, by evaporative cooling with pressurized hot water (42). Hydrogen for the desulfurizer and the hydrogen reactions may be provided as recycle reformate (28, 28a) or from a mini-CPO (67), or from other sources.

    摘要： An integrated contaminant separator and water-control loop (10) decontaminates a fuel reactant stream of a fuel cell (12). Water passes over surfaces of an ammonia dissolving means (61) within a separator scrubber (58) while the fuel reactant stream simultaneously passes over the surfaces to dissolve contaminants from the fuel reactant stream into the water. An accumulator (68) collects the separated contaminant stream, and ion exchange material (69) integrated within the accumulator removes contaminants from the stream. A water-control pump (84) directs flow of a de-contaminated water stream from the accumulator (68) through a water-control loop (78) having a heat exchanger (86) and back onto the scrubber (58) to flow over the packed bed (62). Separating contaminants from the fuel reactant stream and then isolating and concentrating the separated contaminants within the ion exchange material (69) minimizes cost and maintenance requirements.

    摘要： An integrated fuel cell stack assembly (26) and selective oxidizer bed assembly (200) is provided. The fuel cell stack assembly (26) also includes a number of fuel cells. A fuel inlet manifold (22) and fuel inlet plenum to cell stack (38) manifold are arranged in fluid communication with the fuel stack assembly (26) for supplying to and exhausting from, respectively, the fuel supply in the fuel cells in the fuel stack assembly (26). The bed resides in said fuel inlet manifold. The bed includes a selective oxidation catalyst with a heat exchange fluid conduit routed therethrough. Oxygen-containing gas is supplied into the bed via the input plenum. The temperature of the internal selective oxidizer bed is controlled by the fluid conduit in the bed to reduce carbon monoxide in the fuel.

    摘要： A process gas selective oxidizer assemblage for use in a fuel cell power plant includes one or more catalyzed selective oxidizer process gas flow fields and one or more adjacent non-catalyzed heat exchanger process gas flow fields. The catalyzed selective oxidizer process gas flow fields may be formed with catalyzed pellets or with a monolithic catalyzed open cell foam component. The heat exchanger process gas flow fields are formed by non-catalyzed monolithic open cell foam components which have coolant fluid passages disposed therein. Planar metal sheets form a common wall between the selective oxidizer process gas flow fields and the heat exchanger process gas flow fields. The use of the open cell foam to form the heat exchanger process gas flow fields provides enhanced heat transfer between the reformate gas and the coolant fluid. The use of the foam components in both the heat exchange process gas flow fields and the selective oxidizer process gas flow fields enables the construction of a more compact and lighter weight selective oxidizer assemblage. The repeating components are placed side-by-side in the assemblage, so that one of the catalyzed process gas flow fields operates at a higher temperature than subsequent catalyzed process gas flow fields. The process gas enters the higher temperature catalyzed flow field after it is admixed with air that is injected into the system just prior to the higher temperature flow field. The process gas-air mixture flows through the first higher temperature catalyzed process gas flow field; thence through a non-catalyzed heat exchanger process gas flow field; thence through a lower temperature catalyzed process gas flow field; thence through another heat exchanger process gas flow field; and so on, until the selectively oxidized process gas exits the assemblage.
