  • Thermal and vibrational break for high-temperature gas tubes in a solid-oxide fuel cell
    Patent number: 7008715
    Abstract: A fuel cell assembly or system including flexible metal bellows elements in one or more tubes intended for carrying hot gases during operation of the assembly. The bellows elements include a tubing element having plurality of annular corrugated folds. Thermal expansion and contraction of rigid tubes and of the non-tubular elements of the assembly can lead to buckling, cracking, and failure of the tubes and failure of the assembly or system. The flexible bellows elements, having relatively low axial and radial spring rates thus are able to absorb thermal and vibrational dimensional changes in the assembly. In addition, the corrugations provide significant resistance to axial heat flow and large radiant surface area, thus increasing thermal isolation where desired between relatively hot and relatively cold regions of the assembly.
