Patent ID: 7348093

Claim:
A fuel cell stack, comprising a plurality of individual fuel cells stacked above one another, wherein: each fuel cell comprises a cathode-electrolyte-anode unit applied over a surface of a first structural element which distributes fuel gas over a first electrode surface in said cathode-electrolyte-anode unit; said first structural element faces the first electrode surface and is formed by a perforated foil which is perforated by a plurality of holes; said first structural element is gas-tightly joined with a second structural element to form an enclosure which defines a cavity that is bounded by said first and second structural elements; the fuel gas flows through said cavity and said holes to and from the first electrode surface; on an exterior surface opposite the cathode-electrolyte-anode unit, said enclosure has a distribution configuration for distributing an oxidizing gas over a surface of a second electrode of an adjacent enclosure, so that the stack is formed by a plurality of enclosures arranged above one another, with a cathode-electrolyte-anode unit and said distribution configuration situated between the foil and further structure of adjacent enclosures in said stack.
