Fuel cell stack with internal fuel manifold configuration

A fuel cell stack, comprising:

• a plurality of plate shaped fuel cells which are internally manifolded on a fuel side and externally manifolded on an oxidizer side;
• and
• at least one fuel manifold located between adjacent fuel cells;
• wherein the at least one manifold comprises:
• a plate shaped box comprising at least one fuel delivery opening in fluid communication with fuel cell fuel inlet riser openings and at least one fuel outlet opening in fluid communication with fuel cell fuel outlet riser openings;
• a fuel delivery port comprising a fuel inlet conduit adapted to provide a fuel inlet stream into the fuel manifold, and
• a fuel outlet port comprising a fuel outlet conduit adapted to remove a fuel outlet stream from the fuel manifold;
• wherein the plate shaped box comprises a top wall, a bottom wall, two opposite end walls, and two opposite side walls, said end walls and said side walls extending upwardly from the bottom wall to the top wall,
• wherein said side walls and end walls comprise edge surfaces,
• wherein said top and bottom walls comprise first and second major plate surfaces of the plate shaped box, and
• wherein at least one of the top and the bottom walls of the plate shaped box are located adjacent to the plurality of plate shaped fuel cells.
