摘要： In a solid-oxide fuel cell system, a catalytic reformer unit provides reformate fuel for use by the cells in generating electricity. Both the reformer and the fuel cells require elevated temperatures for satisfactory operation. The reformer unit is provided with a combustion chamber and igniter ahead of the catalytic reformer plates such that, during start-up, fuel/air mixture normally destined for reformation may be ignited in the combustion chamber to provide a hot combustion exhaust which is fed through the catalytic reformer and the anode reformate flow spaces to assist in rapidly bringing the fuel cell system to operating temperature.

摘要： A method for improving the efficiency of a hydrocarbon catalytic reformer and close-coupled fuel cell system by recycling a percentage of the anode exhaust syngas directly into the reformer in a range between about 20% and about 60%. Oxygen is supplied to the reformer at start-up. Under equilibrium conditions, oxygen required for reforming of hydrocarbon fuel is derived entirely from endothermic reforming of water and carbon dioxide in the recycled syngas. Recycling of anode syngas into the reformer increases fuel efficiency, adds excess water to the reformate to increase protection against anode coking, and protects the fuel cell stack against air- and water-borne contaminants. A method for producing an excess amount of syngas for exporting for other purposes is also provided.

摘要： A fuel cell assembly comprising a plurality of individual fuel cells, especially a solid-oxide fuel cell assembly. The cells are organized into a plurality of stacks, preferably two stacks, disposed side-by-side rather than end-to-end as in a prior art monolithic single stack. This arrangement makes the assembly compact physically, which can be highly desirable in some fuel cell applications. The stacks are connected conventionally in series electrically but are supplied with air and fuel in parallel to shorten the distribution manifolds and improve uniformity of distribution and exhaust among all the cells.

摘要： In a solid-oxide fuel cell assembly, at least one positive displacement air supply (PDAS) pump supplies at least a portion of the air required for various functional air streams through the assembly. Mass air flow through each PDAS pump is readily controlled to a predetermined flow by controlling the rotational speed of the pump, obviating the need for an MAF sensor and control valve. Preferably, each different air stream through the assembly is controlled by its own PDAS pump, sized for the required flow, allowing each to operate at its optimal pressure and thereby minimizing the parasitic electrical cost of providing air to the SOFC assembly.

摘要： A fuel cell assembly or system including flexible metal bellows elements in one or more tubes intended for carrying hot gases during operation of the assembly. The bellows elements include a tubing element having plurality of annular corrugated folds. Thermal expansion and contraction of rigid tubes and of the non-tubular elements of the assembly can lead to buckling, cracking, and failure of the tubes and failure of the assembly or system. The flexible bellows elements, having relatively low axial and radial spring rates thus are able to absorb thermal and vibrational dimensional changes in the assembly. In addition, the corrugations provide significant resistance to axial heat flow and large radiant surface area, thus increasing thermal isolation where desired between relatively hot and relatively cold regions of the assembly.

摘要： A fuel cell system including a fuel cell stack, a reformer system, and a waste energy recovery (or heat exchanger) assembly is presented. The waste energy recovery assembly receives an anode supply and a cathode supply that are heated by exhaust gases from the fuel cell stack. The heated anode supply and cathode supply are then directed to the fuel cell stack. The waste energy recovery assembly includes a series of stacked plates. The flow direction of the plates alternates from one plate to the next. These plates are alternately stacked until the desired flow area and heat transfer are achieved. Since the direction of flow of each plate is perpendicular to the direction of flow of the next plate in series, the cool (anode and cathode) gases flow along side a plate experiencing a flow of heated exhaust gases and are thusly heated.

摘要： An electronically actuated, air control valve regulates the flow of combustion air to an internal combustion engine. The valve includes an air passage having a throttle valve rotatable therein between a first, minimum air flow position and a second, maximum air flow position. Between the minimum and the maximum air flow positions is a default air flow position for operation of the engine during actuator inoperativeness. A biasing member has a first end operable to impart a force on the valve member in the direction of the default air flow position when the valve member in operable between the minimum air flow position and the default position. Likewise, the biasing member has a second end operable to impart a force on the valve member in the direction of the default air flow position when the valve member is operated in the range between the default air flow position and the maximum air flow position. As a result, a single biasing member operates to position the throttle valve at a default air flow position between the minimum and the maximum air flow positions across the entire range of positions.

摘要： An improved SOFC repeating fuel cell unit comprising three flat plates and a cell retainer. The three flat plates are metallurgically joined (brazed or laser welded) into a subassembly to which is added the fuel cell and cell retainer (which may also be joined as a second subassembly). Each flat plate performs a specific set of functions and can be optimized for those functions. Since the plates are flat and designed to overlap in loaded areas, the fuel cell unit is not prone to dimensional collapse which eliminates the internal reinforcements of the prior art design. The cell retainer is formed to provide a self-locating and locking feature for the fuel cell and decouples thermal stresses from the thin ceramic fuel cell.

摘要： A system for adding sulfur to a fuel cell stack, having a reformer adapted to reform a hydrocarbon fuel stream containing sulfur contaminants, thereby providing a reformate stream having sulfur; a sulfur trap fluidly coupled downstream of the reformer for removing sulfur from the reformate stream, thereby providing a desulfurized reformate stream; and a metering device in fluid communication with the reformate stream upstream of the sulfur trap and with the desulfurized reformate stream downstream of the sulfur trap. The metering device is adapted to bypass a portion of the reformate stream to mix with the desulfurized reformate stream, thereby producing a conditioned reformate stream having a predetermined sulfur concentration that gives an acceptable balance of minimal drop in initial power with the desired maximum stability of operation over prolonged periods for the fuel cell stack.
