Abstract
A solid oxide fuel cell stack incorporates metallic interconnects each of which includes a fuel intake manifold, a fuel exhaust manifold, an oxidant intake manifold and an oxidant exhaust manifold. The fuel side of the interconnect defines a fuel flow field surrounded by a continuous sealing surface and in fluid communication with the fuel intake and exhaust manifold. The oxidant side of the interconnect defines an oxidant flow field surrounded by a continuous sealing surface and in fluid communication with the oxidant intake and exhaust manifolds. The interconnect may be fabricated by brazing together three stainless steel plates having overlapping openings to permit the exclusionary flow of fuel and oxidant through the interconnect.
