Abstract: A solid state sintered material is described that includes a mixed oxide of lanthanum, strontium, cobalt, iron and oxygen, and CaCO 3 inclusions. The solid state sintered material can also include calcium oxide, which can form from thermal composition of calcium carbonate. The solid state sintered material can also include a pore-forming particulate material such as carbon black and/or a doped ceramic metal oxide ionic conductor such as Sm-doped ceria uniformly dispersed in the solid state sintered material. The solid state sintered material can be formed from a two-step process in which a portion of the CaCO 3 is mixed with the mixed oxide materials and heated to form porous agglomerates, and the remaining CaCO 3 is added during the formation of a sintering paste. The solid state sintered material described herein can be used as a cathode material (28) for a solid oxide fuel cell (20).

Abstract: A cathode of a solid-oxide fuel cell includes a first ionic conducting layer, a second layer deposited over the first layer and formed from a mixed ionic and electronic conductor layer including an oxygen ion conducting phase, and a third layer deposited over the second layer and formed from a mixed ionic and electronic conductor layer. A sintering aid and pore formers are added to the second layer and the third layer to establish ionic, electronic, and gas diffusion paths that are contiguous. By adjusting the microstructure of the second and the third layer, a high performance low resistance cathode is formed that bonds well to the electrolyte, is highly electro-catalytic, and has a relatively low overall resistance. By using inexpensive and readily available substances as sintering aid and as pore formers, a low-cost cathode is provided.

Abstract: An improved LSCF 6428 perovskite material of the type La 12z Sr x+z Co 0.2+a Fe 0.8+b O 3-´ wherein x = 0.4, z = (0 - 0.1), a = (.01 €• 0.04), and b = (0.05 €• 0.15) for use as an SOFC cathode having increased electronic and ionic conductivity. The general formula is similar to the prior art formulae (La 0.6 Sr 0.4 ) 1-z CO 0.2 Fe 0.8 O 3-´ and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-´ but applies the z term to La and Sr independently as well as reducing the overall content of La. Further, by adding a small amount (a) of extra Co ions, catalytic activity, conductivity, and sinterability are further enhanced. Adding small amounts (b) of Fe and/or Fe and Co moderates the thermal expansion coefficient with no adverse effect on crystal structure or fuel cell performance. Improved sinterability, microstructure, and reduced film cracking result in high power density of fuel cells. An inherently low-cost solid state reaction method is described.

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.
