Abstract: A fuel cell stack comprising a plurality of serially-connected fuel cell stages (132,332), each stage comprising a plurality of fuel cells (110a,b, 21oa,b, 310a,b,c,d) arranged electrically in parallel such that each stage has the voltage drop of a single fuel cell but current output defined by the total cell area. The assembled stack thus comprises essentially a plurality of internal fuel cell stacks arranged in parallel, each stack having the same voltage, and the stack currents being additive. The total voltage is the same as for a prior art stack of the same number of stages, but the current and hence the power output is multiplied over that of a single-cell stack by the number of internal fuel cell stacks. Preferably, each stage is a cassette including a plurality of windows (123a,b, 223a,b, 323a,b,c,d) for receiving the individual fuel cell units(110a,b, 21oa,b, 310a,b,c,d) ; a plurality of anode and cathode interconnects (30,35); and a single separator plate (28).

Abstract: An electrically-conductive mesh spacer (42) incorporated into the hydrogen and air gas flow spaces (22,24) between each anode (14) and cathode (16) and its adjacent interconnect (40) in a fuel cell stack (76). The mesh is formed of metal strands and is formed into a predetermined three-dimensional pattern to make contact at a plurality of points on the surfaces of the electrode (14,16) and the interconnect element (40). The formed mesh spacer (42) is secured as by brazing to the interconnect element at a plurality of locations to form an interconnect, which preserves the pattern during assembly of a fuel cell stack (76). The height (48') of the formed pattern is greater than the height of a gas flow space after fuel cell assembly, such that the mesh spacer is slightly compressed (48") during assembly of a fuel cell stack. Because the metal mesh is both compliant and resilient, the compressed spacer (48") is continuously urged into mechanical and electrical contact with its electrode (14,16) over all temperatures and pressures to which the fuel cell assembly may be subjected during use.

Abstract: 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.

Abstract: Interconnects and perimeter spacers for a fuel cell stack are provided as flexible elements which can conform to non-planarities in a stack's electrolyte elements and thereby avoid inducing torsional stresses in the electrolyte elements. The interconnects are foil elements about 0.005inches thick, formed of a superalloy such as Hastelloy, Haynes 230, or a stainless steel. The perimeter spacers comprise a plurality of laminate thin spacer elements, each thin spacer element being a laminate of superalloy and a "soft" material such as copper, nickel, or mica. The spacer elements can slide past one another; thus the perimeter spacers can be physically thick, to form the gas flow spaces within the stack, while also being torsionally flexible.

Abstract: During manufacture of an SOFC assembly, an inhibitor is included to prevent migration of silver braze during subsequent use of the SOFC assembly. The inhibitor may take any of several forms, either individually or in combination. Inhibitors comprehended by the present invention include, but are not limited to: a) a mechanical barrier (146) that can be printed or dispensed onto one or more SOFC stack elements around the braze (38) areas to prevent mechanically-driven migration; b) an electrically insulating feature (150) in the electrolyte or interlayer over the electrolyte layer (34) in the seal margins to prevent electrical potential-driven migration; and c) chemical modification of the braze (138) itself as by addition of an alloying metal such as palladium.

Abstract: An interconnect element for electrically connecting an anode and a cathode in adjacent fuel cells in a fuel cell stack, wherein said interconnect element has at least one featured surface including dimples, bosses, and/or pins arranged in a two-dimensional pattern. Preferably, both surfaces are featured, as by mechanical dimpling, embossing, or chemical etching, so that protrusions of the interconnect surface extend into either or both of the adjacent gas flow spaces to make electrical contact with the surfaces of the anode and cathode. This permits conduction of heat from the anode. The protrusions create turbulence in gas flowing through the flow spaces, which increases hydrogen consumption at the anode and hence electric output of the cell.
