Abstract: A flexible seal for use in a solid oxide fuel cell stack is formed from a fiber matrix with a plurality of solid particles through tape casting method. The fibers and particles are preferably ceramic and may be formed from alumina or zirconia. The seal may be formed by forming a slurry of fibers, particles, a binder and a non-aqueous solvent, tape casting the slurry, drying the tape seal, die-cutting, prior to installation in the fuel cell stack.

Abstract: A multilayer contact approach for use in a planar solid oxide fuel cell stack includes at least 3 layers of an electrically conductive perovskite which has a coefficient of thermal expansion closely matching the fuel cell material. The perovskite material may comprise La1-xEx Co0.6Ni0.4O3 where E is a alkaline earth metal and x is greater than or equal to zero. The middle layer is a stress relief layer which may fracture during thermal cycling to relieve stress, but remains conductive and prevents mechanical damage of more critical interfaces.

Abstract: 6A fifth wheel trailer pin assembly characterized by having a horizontally pivoting joint to reduce the transmission of lateral flex and stress between the units coupled by the hitching assembly. The trailer pin assembly is designed to be used with conventional fifth wheel locking assemblies, which are designed to allow for horizontal rotation of the trailer pin within the locking assembly and far longitudinal pivoting between the units coupled by the hitching assembly, to provide a fifth wheel hitching system which minimizes the transmission of unwanted forces and stresses between the units that are coupled together.
