About LSCF-GDC Composite Cathode Powder

LSCF-GDCComposite Cathode Powder

Product Code: 6211639

This composite 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 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 oruspensions.

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 powder's particle size distribution will be bimodal onceprocessing is complete.

This cathode powder has been created forSolid Oxide Fuel Cell (SOFC) applications in mind.

FAQs of LSCF-GDC Composite Cathode Powder:

Q: How should LSCF-GDC Composite Cathode Powder be stored to maintain its properties?

A: LSCF-GDC Composite Cathode Powder should be stored in moisture-free, airtight containers, preferably in sealed polyethylene jars or bags, as exposure to moisture can affect its purity and performance.

Q: What benefits does the ultrafine particle size and high surface area provide in SOFC applications?

A: The ultrafine particle size (D50 <1 m) and high specific surface area (>8 m/g) increase the active interface for electrochemical reactions, which boosts SOFC efficiency by facilitating oxygen ion transport and enhancing reaction rates.

Q: When is the optimal sintering temperature range for this cathode powder?

A: This composite cathode powder is optimized for sintering within the temperature range of 11001200C, ensuring sufficient densification while preserving porosity essential for efficient operation in SOFCs.

Q: Where is this LSCF-GDC composite powder distributed and who can order it?

A: The powder is available for distribution across the United States and can be ordered by manufacturers, researchers, and suppliers involved in SOFC, fuel cell, or membrane technologies.

Q: What process should be followed during the fabrication of electrodes using this material?

A: During electrode fabrication, mix and apply the powder under controlled atmospheric conditions to prevent moisture exposure, then sinter at the recommended range (11001200C) to achieve optimal mechanical and electrochemical characteristics.

Q: What applications are most suitable for this LSCF-GDC composite powder?

A: This powder is most suitable for Solid Oxide Fuel Cells (SOFCs) as a cathode material, as well as for oxygen separation membranes requiring high electrical conductivity and thermal stability.

Q: How does the powders purity and low moisture content benefit industrial use?

A: A high purity level (99.9%) and moisture content below 0.5% help maintain consistency in performance, reduce contamination risks, and enhance the longevity of devices utilizing this cathode material.
