Abstract
A rod assembly and method for supporting rods includes opposing end plates for supporting opposing ends of a plurality of solid oxide fuel cell rods with each rod comprising a hollow gas conduit passing there through. Each rod end is supported by an annular flexure configured to provide a gas/liquid tight seal between the rod ends and the end plates. Each annular flexure includes a flexible portion surrounding the rod end such that forces imparted to either or both of the rod and the end plate act to elastically deform the annular flexure without damaging the rods. The rod assembly operates and a Solid Oxide Fuel Cell (SOFC) with operating temperatures of 500 to 1000° C.
