  • Patent number: 8455154
    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.

  • Publication number: 20110297228
    Abstract: The invention describes a polymer that is composed of a fluoropolymer modified with a UV absorber. The UV absorber is grafted to the polymeric backbone of the fluoropolymer. Optionally, a HALS can also be grated to the polymeric backbone of the fluoropolymer. Incorporation or the absorber or stabilizer helps to reduce degradation of underlying layers such as an encapsulant while still allowing useful light energy to pass through the layers to a device, such as a photovoltaic device.
