摘要： A solid oxide fuel cell (SOFC) includes a plurality of subassemblies. Each subassembly includes at least one subcell of a first electrode, a second electrode and an electrolyte between the first and second electrodes. A first bonding layer is at the second electrode and an interconnect layer is at the first bonding layer distal to the electrolyte. A second bonding layer that is compositionally distinct from the first bonding layer is at the interconnect layer, whereby the interconnect partitions the first and second bonding layers. A method of fabricating a fuel cell assembly includes co-firing at least two subassemblies using a third bonding layer that is microstructurally or compositionally distinct from the second bonding layer.

摘要： A solid oxide fuel cell includes an anode layer, an electrolyte layer over a surface of the anode layer, and a cathode layer over a surface of the electrolyte layer. The cathode layer includes a cathode bulk layer, a porous cathode functional layer at an electrolyte, an intermediate cathode layer partitioning the cathode bulk layer and the porous cathode functional layer, the porous intermediate cathode layer having a porosity greater than that of the cathode bulk layer. The solid oxide fuel cells can be combined to form subassemblies that are bonded together to form solid oxide fuel cell assemblies.

摘要： An interconnect material is formed by combining a lanthanum-doped strontium titanate with an aliovalent transition metal to form a precursor composition and sintering the precursor composition to form the interconnect material. The aliovalent transition metal can be an electron-acceptor dopant, such as manganese, cobalt, nickel or iron, or the aliovalent transition metal can be an electron-donor dopant, such as niobium or tungsten. A solid oxide fuel cell, or a strontium titanate varistor, or a strontium titanate capacitor can include the interconnect material that includes a lanthanum-doped strontium titanate that is further doped with an aliovalent transition metal.

摘要： A glass-ceramic seal for ionic transport devices such as solid oxide fuel cell stacks or oxygen transport membrane applications. Preferred embodiments of the present invention comprise glass-ceramic sealant material based on a Barium-Aluminum-Silica system, which exhibits a high enough coefficient of thermal expansion to closely match the overall CTE of a SOFC cell/stack (preferably from about 11 to 12.8 ppm/° C.), good sintering behavior, and a very low residual glass phase (which contributes to the stability of the seal).
