Abstracts:
The invention relates to an electrode (200) for metal/air cells (303) in which, in the event of discharge on the cathode side, oxygen is reduced with formation of hydroxide ions and, in the event of charging, hydroxide ions are oxidized with formation of oxygen. Said electrode is formed as a layer and has a first flat side (211) and a second flat side (212) facing away from the first flat side (211). The electrode (200) comprises a porous matrix (213) made of a polymer binder material, in which a first and a second catalyst (214 and 215) are embedded, the first catalyst (214) catalysing the oxygen formation in a charging situation and the second catalyst (215) catalysing the reduction of oxygen in a discharging situation. The first catalyst (214) is contained within the matrix (213) on the first flat side (211) in a higher concentration than on the second flat side (212). The electrode (200) is used in particular as an oxygen cathode in metal/air cells (303). In order to produce an electrode (200) of this kind, a mixture of the polymer binder material and the second catalyst (215) is formed and is processed to form a layer. The first catalyst (214) is then incorporated into one flat side (211) of the layer. Prior to the further processing, the electrode (200) formed can be combined with an air distributor layer (202) to form a multi-layer composite (201).

Die Elektrode (200) umfasst eine poröse Matrix (213) aus einem polymeren Bindermaterial, in die ein erster und ein zweiter Katalysator (214 und 215) eingebettet sind, wobei der erste Katalysator (214) die Sauerstoffbildung im Ladefall und der zweite Katalysator (215) die Reduktion von Sauerstoff im Entladefall katalysiert. Der erste Katalysator (214) ist innerhalb der Matrix (213) an der ersten Flachseite (211) in einer höheren Konzentration enthalten als an der zweiten Flachseite (212). Die Elektrode (200) findet insbesondere Anwendung als Sauerstoffkathode in Metall/Luft-Zellen (303). Zur Herstellung einer solchen Elektrode (200) wird eine Mischung aus dem polymeren Bindermaterial und dem zweiten Katalysator (215) gebildet und zu einer Schicht verarbeitet. Der erste Katalysator (214) wird dann in die eine Flachseite (211) der Schicht eingearbeitet. Vor der Weiterverarbeitung kann die gebildete Elektrode (200) mit einer Luftverteilerschicht (202) zu einem Schichtverbund (201) kombiniert werden.
