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: 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.
