    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.
