Abstract

Die Erfindung bezieht sich auf eine Zwei-Schicht-Kathode für eine Hochtemperatur-Brennstoffzelle. Die Zwei-Schicht-Kathode umfasst eine Kathode sowie eine Kathodenfunktionsschicht auf einem Elektrolyt. Sie ist dadurch gekennzeichnet, dass die Kathodenfunktionsschicht Silber bei einem Restanteil Lanthan-Strontium-Manganit (LaSrMn03: LSM) enthält, insbesondere mit einem Silberanteil von mindestens 60 Vol %. Besonders vorteilhaft umfaßt auch die Kathode Silber, beispielsweise in einer Konzentration von 30 Vol %. Als Verfahren zur Herstellung der erfindungsgemässen Zwei-Schicht-Kathode wird ein Siebdruckverfahren oder 20 ein Nasssprühverfahren vorgeschlagen.
