Thiscomposite cathode powder is a 50/50 wt% mixture of Lanthanum Strontium CobaltFerrite (LSCF) and Gadolinium Doped Ceria (GDC), and is typically used as thefirst layer in a two-layer cathode, where the second (top) layer is pure LSCF.This two-layer approach provides higher performance than single-layer LSCFcathodes, and can be used with all ceramic electrolyte materials. A ceriabarrier layer is recommended when using LSCF/GDC cathodes with zirconia basedelectrolytes. The LSCF/GDC cathode material can be applied by screen printing,painting or spraying after it is formulated into appropriate inks orsuspensions.
Sincethis LSCF-GDC Composite Cathode Powder is a mixed component powder we do nothave a particle size specification. This powder uses LSCF-P and GDC10-TC as itscomponents. The powderâs particle size distribution will be bimodal onceprocessing is complete.
This cathode powder has been created forSolid Oxide Fuel Cell (SOFC) applications in mind.
