摘要： A current carrier for a solid oxide fuel cell system comprising a current-carrying core formed of a high-conductivity metallic material such as copper, brass, bronze, silver, silver-copper alloys, molybdenum, tungsten, or the like, and a protective jacket surrounding the core material. Preferably, the jacket is metallurgically bonded to the core. The jacket is formed of a high temperature alloy such as stainless steel, nickel, or a nickel alloy. The jacket is structurally competent to maintain the form of the electrical carrier at elevated temperatures at which the core material may be structurally incompetent. The current carrier may be sized comparable to conventional copper cables. The carrier is attached to a fuel cell current collector by a clamp assembly having a large surface contact area. Preferably, a contact paste consisting of fine silver particles forms a diffusion bond between the clamp and the carrier jacket, resulting in a low-loss connection.

摘要： In a modular fuel cell cassette for forming a fuel cell stack, anode openings in the mounting plate and separator plate are separated and connected by modular spacer rings such that the cassette is incompressible at operating temperatures and compressive loads within the stack. The spacer rings are formed in modules wherein all of the rings required for all of the anode supply chimneys or all of the anode exhaust chimneys of any given cassette are ganged together and include a perimeter rail to which the rings are connected which automatically orients and positions the rings within the cassette during assembly thereof. The present invention eliminates the prior art need for individually positioning and spot welding each prior art ring in place prior to assembly of a prior art cassette. Two different structural embodiments for a spacer ring module are disclosed.

摘要： An SOFC stack module including an integral individual stack manifold containing all of the gas pathways necessary for supply and exhaust of fuel gas and cathode air to and from the stack chimneys. The stack is mounted and hermetically joined directly to the manifold without an intermediate base plate. Flanges at the inlet and outlet ports couple to system distributary manifolds via high temperature sealing joints. The manifold preferably is fabricated of a ferritic stainless steel, and may be formed in a one-piece casting, a combination of multiple castings and stamped plates metallurgically joined (brazed or welded together), or stamped from sheet metal stock. Preferably, the manifold includes fin structures extending into adjacent fuel gas and cathode air chambers to enhance balancing of temperatures by heat exchange therebetween. Heat exchange may be further improved by configuring the manifold to have a plurality of interleaved anode and cathode gas supply chambers.

摘要： An electrical interconnect for a solid-oxide fuel cell stack assembly, including a novel sintering paste and an improved manufacturing process for an anode and cathode electrical contacts is disclosed. On the anode side, the paste contains a metallic oxide such as NiO, and an amount of sacrificial pore-forming particles, such as carbon particles or polymer spheres, which are vaporized during sintering of the paste, resulting in a very porous connection having good electrical conductivity and good adhesion. A preferred level of pore-former in the paste is about 40 volume percent. On the cathode side, the paste contains a noble metal such as for example, gold, platinum, palladium or rhodium, and an amount of the sacrificial pore-forming particles. The paste may be applied to the surfaces in a grid pattern or, because the resulting contact is porous after sintering, it may be applied as a continuous layer.

摘要： A modular fuel cell cassette for use in assembling a fuel cell stack comprising a metal separator plate and a metal cell-mounting plate joined at their edges to form a hollow cassette. A fuel cell subassembly is attached to the mounting plate and extends through an opening in the mounting plate. The plates include openings to form chimney manifolds for supply and exhaust of fuel gas to the anode and air to the cathode. A conductive interconnect element extends from the fuel cell subassembly to make contact with the next cassette in a stack. The anode openings in the mounting plate and separator plate are separated by spacer rings such that the cassette is incompressible. A fuel cell stack comprises a plurality of cassettes, the mounting plate of one cassette being attached to, and insulated from, the separator plate of the next-adjacent cassette by a dielectric seal surrounding the interconnect.

摘要： A fuel cell module having four sheet metal parts stamped from flat stock. The parts do not require any forming operations such as folding or dishing. Each part may have a different thickness to suit its function. The first part is a cell mounting frame for receiving and supporting a PEN fuel cell element. The second part is a cathode spacer, the thickness of the spacer determining the height of the cathode air flow field. The third part is an anode spacer, the thickness of spacer determining the height of the anode fuel flow field. The fourth part is a separator plate for separating the anode gas flow in one cell from the cathode air flow in an adjacent cell in a fuel cell stack. The four plates are joined by welding or brazing and may be assembled in any order or combination which suits the assembly process. Any desired number of modules may be stacked together to form a fuel cell stack.

摘要： A minimum joint thickness can be assured by incorporating beads or particles having a diameter corresponding to the joint thickness desired and which are infusible at the brazing temperature. Preferably such particles are formed of high-melting metals, metal oxides, ceramics, or cermets and are mixed into the alloy paste prior to fusing. In a preferred embodiment, the particle-containing paste is mixed with a non-flux carrier to facilitate application to the elements to be brazed. Exemplary application methods may include painting, rolling, screening, or extrusion dispensing. Brazing alloys in accordance with the invention are useful in bonding ceramics to ceramics, ceramics to metals, and metals to metals.

摘要： In a solid-oxide fuel cell system, the fuel cell tail gas contains significant residual amounts of combustibles which are burned in a combustor with spent cathode air to reduce system emissions and to reclaim chemical energy in the form of heat, the hot exhaust being used to pre-heat air entering the fuel cell system. The tail gas combustibles content can vary widely as can the combustion temperature. When the temperature becomes unacceptably low, a control valve in the spent cathode air return is adjusted to divert a portion of the air around the combustor, thus enriching the fuel/air mixture and causing the combustion temperature to increase. When the temperature becomes unacceptably high, a control valve in the combustor fresh air supply is adjusted to provide more air, thus causing the mixture to become leaner and the combustion temperature to decrease.

摘要： A solid-oxide fuel cell system including an integrated reforming unit comprising a hydrocarbon fuel reformer; an integral tail gas and cathode air combustor and reformer heat exchanger; a fuel pre-heater and fuel injector cooler; a fuel injector and fuel/air mixer and vaporizer; a reforming air pre-heating heat exchanger; a reforming air temperature control valve and means; and a pre-reformer start-up combustor. The integration of a plate reformer, tail gas combustor, and combustor gas heat exchanger allows for efficient operation modes of the reformer, both endothermic and exothermic as desired.
