LSCF-GDC Composite Cathode Powder
This composite cathode powder is a 50/50 wt% mixture of Lanthanum Strontium Cobalt Ferrite (LSCF) and Gadolinium Doped Ceria (GDC), and is typically used as the first layer in a two-layer cathode, where the second (top) layer is pure LSCF. This two-layer approach provides higher performance than single-layer LSCF cathodes, and can be used with all ceramic electrolyte materials. A ceria barrier layer is recommended when using LSCF/GDC cathodes with zirconia based electrolytes. The LSCF/GDC cathode material can be applied by screen printing, painting or spraying after it is formulated into appropriate inks or suspensions.
Since this LSCF-GDC Composite Cathode Powder is a mixed component powder we do not have a particle size specification. This powder uses LSCF-P and GDC10-TC as its components. The powder’s particle size distribution will be bimodal once processing is complete.
This cathode powder has been created for Solid Oxide Fuel Cell (SOFC) applications in mind.
