Abstract:
A solid oxide fuel cell stack comprising:a plurality of planar integral component fuel cell units, each said planar integral component fuel cell unit comprising a porous anode layer, a porous cathode layer, and a dense electrolyte layer disposed between said porous anode layer and said porous cathode layer;said porous anode layer forming a plurality of substantially parallel fuel gas channels on an anode surface facing away from said dense electrolyte layer and extending from a first anode side to an opposite anode side;said porous cathode layer forming a plurality of substantially parallel oxidant gas channels on a cathode surface facing away from said dense electrolyte layer and extending from a first cathode side to an opposite cathode side; anda substantially flat flexible metallic foil interconnect disposed between said porous anode layer and said porous cathode layer of adjacent said integral component fuel cell units.
