摘要： A fuel cell includes a cathode-electrolyte-anode unit, and a perforated foil structure distributes fuel gas over an electrode surface thereof. Longitudinal axes of at least some of the holes forming perforations in the foil are inclined differently relative to the foil surface such that, near a fuel gas feed, the outlet openings of the holes facing the electrode are oriented at least slightly toward the area of the fuel gas outlet from the fuel cell. Near a fuel gas outlet, the inlet openings of the holes facing the electrode are oriented at least slightly to the area of the fuel gas feed. However, holes whose inlet openings facing away from the electrode are oriented toward the fuel gas feed, and holes whose outlet openings facing away from the electrode are oriented toward the fuel gas outlet, may also be arranged alternately side-by-side.

摘要： A fuel cell stack comprises several mutually stacked fuel cells, each of which has a cathode-electrolyte-anode unit, and a perforated foil for distributing a fuel gas over a first electrode surface. The foil carries the cathode-electrolyte-anode unit and is assembled with a further structure to form an enclosure having a cavity through which fuel gas flows to the first electrode. Opposite the cathode-electrolyte-anode unit, each enclosure has a distribution configuration for distributing air-oxygen over the surface of the second electrode of an adjacent enclosure, so that a cathode-electrolyte-anode unit and a distribution configuration are situated between the foil and the further structure of adjacent enclosures in the stack. In addition, the stack contains at least one bracing enclosure whose walls have an impermeable construction and which is filled with a material expands when heated.
