Abstract:
1. Fuel cell comprising: a cathode-electrolyte-anode unit; and a structure which distributes fuel gas over an electrode surface of said cathode-electrolyte-anode unit; wherein, a surface of said structure which faces the electrode comprises a perforated foil; and longitudinal axes of at least some holes which perforate said foil are inclined with respect to the foil surface, wherein: the longitudinal axes of at least some of the holes are inclined differently with respect to the foil surface; in an area of a fuel gas feed into the fuel cell, outlet openings of holes facing the electrode, as a matter of priority, are at least slightly oriented toward a fuel gas outlet from the fuel cell; and in an area of a fuel gas outlet from the fuel cell, inlet openings of holes facing the electrode, as a matter of priority, are at least slightly oriented toward the fuel gas feed into the fuel cell.
