(US5227256-A)      A fully internally manifold fuel cell stack is provided by each separator plate, current collector, electrode, and electrolyte in the fuel cell stack having 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 set 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. Conduits through the extended manifold structure of a reactant gas manifol provide communication to interspersed reforming chambers. Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing.    ADVANTAGE -   The 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.    (JP6163063-A)      Separator plates (40,40',40'') and electrolytes (20) in a fuel cell stack have several aligned perforations (24,25) forming gas manifolds extending for the length of the stack. Each perforation is surrounded by a flattened manifold wet seat (45,46,51) connecting electrolytes on each plate forming separator plate/electrolyte wet seals under operating conditions.    Conduits provide gas communication between manifold sets and anode chambers and cathode chambers on respective faces of the plates. Further conduits (50) provide communication to interspersed reforming chambers.    USE/ADVANTAGE -   Provides internal manifolding for reforming hydrocarbons without poisoning catalyst in high temp. fuel cell stacks.
