Abstract: A solid oxide fuel cell stack having a plurality of cassettes and a glass composite seal disposed between the sealing surfaces of adjacent cassettes, thereby joining the cassettes and providing a hermetic seal therebetween. The glass composite seal includes an alkaline earth aluminosilicate (AEAS) glass disposed about a viscous glass such that the AEAS glass retains the viscous glass in a predetermined position between the first and second sealing surfaces. The AEAS glass provides geometric stability to the glass composite seal to maintain the proper distance between the adjacent cassettes while the viscous glass provides for a compliant and self-healing seal. The glass composite seal may include fibers, powders, and/or beads of zirconium oxide, aluminum oxide, yttria-stabilized zirconia (YSZ), or mixtures thereof, to enhance the desirable properties of the glass composite seal.

Abstract: A method of making a solid oxide fuel cell (SOFC) stack that includes the steps of applying a seal enhancing coating and a conductive coating onto respective surfaces of a separator plate and simultaneously co-firing the coatings in a reducing atmosphere. The method may also include, prior to the step of co-firing, the step of assembling a plurality of separator plates with complementary cell-retainer assemblies to form a plurality of fuel cell cassettes. The fuel cell cassettes are then stacked with a glass sealant applied between the fuel cell cassettes to form a SOFC stack. The entire SOFC stack is then co-fired in a reducing atmosphere such that the seal enhancing and conductive coatings are bonded into the respective surfaces and the glass sealant devitrify to form a glass seal joining and sealing the cassettes of the SOFC stack.

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: 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: 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.
