A radial planar fuel cell stack comprises an internal manifold having a first interior cavity and a second interior cavity. A plurality of single cells having an anode layer, a cathode layer, and an electrolyte layer therebetween are disposed about the manifold. A manifold bracket operatively fixes the manifold to at least one of the single cells. The manifold bracket describes a channel in communication with at least one of the first and second interior cavities. A porous element is disposed in the channel and ensures uniform distribution of gases over 360&deg;.

Radial planar fuel cell stack construction for solid electrolytes

A sealant for a solid oxide fuel cell comprises a glass material that acts as a matrix, with the glass material being present between about 40 to 90 wt. %. A gap-filler material is also in the sealant and selected from the group consisting of a metal material and a ceramic material, with the gap-filler material being present between about 10 to 60 wt. %. The sealant can seal a gap as large as about 3 mm.
