This powder is moisture-sensitive and requires dry storage to prevent agglomeration and performance degradation. Processing must yield dense, pinhole-free layers to function as an effective diffusion barrier in SOFCs.
- Moisture Sensitivity: Moisture uptake above 1 wt.% can cause particle agglomeration and compromise electrolyte performance.
- Barrier Layer Function: The powder must be processed into a dense, pinhole-free layer to effectively suppress cation interdiffusion between cathode and electrolyte.
- Storage Conditions: Store in a dry environment and keep containers tightly sealed when not in use to prevent contamination.
How does Gadolinium-Doped Ceria Powder prevent strontium and cobalt migration in SOFCs?
As a functional barrier layer between cobaltite cathodes and zirconia electrolytes, this GDC powder suppresses Sr and Co interdiffusion, improving long-term stability. The product is specifically designed for this application, as stated in the product overview.
Can Gadolinium-Doped Ceria Powder be used with both noble-metal and perovskite-based electrodes?
Yes, the powder has good chemical compatibility with both noble-metal and perovskite-based electrodes, as noted in the performance features. This makes it suitable for a wide range of SOFC configurations.
What are the recommended storage conditions for Gadolinium-Doped Ceria Powder to prevent performance degradation?
Store in a dry environment and keep containers tightly sealed when not in use to prevent moisture uptake and contamination. The as-received moisture content is <1 wt.%, and improper storage can compromise the powder's handling and sintering behavior.
This GDC10 powder (Gd₀.₁Ce₀.₉O₂₋δ) provides high ionic conductivity below 700 °C and acts as a functional diffusion barrier against Sr and Co migration in IT-SOFCs, but requires strict moisture control during storage to prevent uptake and contamination.
Positive
- Superior low-temperature ionic conductivity: Exhibits high ionic conduction below 700 °C, making it suitable for intermediate-temperature SOFC electrolytes and other electrochemical devices operating in this range.
- Effective diffusion barrier layer: Prevents Sr and Co migration from cobaltite cathodes into zirconia electrolytes, improving long-term cell stability when used as a functional barrier layer.
Trade-offs
- Moisture-sensitive storage required: Must be stored in a dry environment and kept in tightly sealed containers to prevent moisture uptake and contamination, which could affect powder properties and processing.
