ABSTRACT:
A fully internally manifolded fuel cell stack is provided by each separator plate, current collector, electrode, and electrolyte in the fuel cell stack having a plurality of aligned perforations forming gas manifolds extending for the length of the cell stack. Each perforation through the separator plate is surrounded by a flattened manifold wet seal structure extending to contact the current collector and/or electrode on each face of the separator plate to form electrolyte/electrode wet seals under cell operating conditions. Conduits through the extended manifold wet seal structure provide gas communication between one set of manifolds and the anode chambers on one face of the separator plates, conduits through the extended manifold wet seal structure on the opposite face of the separator plates provide gas communication between a second set of the manifolds and the cathode chambers on the other face of the separator plates, and conduits through the extended manifold structure of a reactant gas manifold provide communication to interspersed reforming chambers. Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing. This structure provides fully internal manifolding of and separation of fuel and oxidant gases to each of the unit fuel cells in the fuel cell stack while providing reactant gas to reforming chambers interspersed along the cell axis to reform hydrocarbonaceous gas and supply enhanced hydrogen content to the fuel supply manifold.
