Abstract
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.
