Description
Key Properties & Advantages
LCN164’s performance stems from its perovskite structure and balanced Co/Ni doping:
Controlled Particle Size (0.3–0.6 μm): Enables uniform dispersion in cathode layers, balancing porosity for gas diffusion with sufficient contact area for ORR—critical for maximizing electrochemical activity in IT-SOFCs.
Moderate Specific Surface Area (6–10 m²/g): Provides abundant active sites for oxygen adsorption/desorption while resisting excessive sintering at 600–800°C, ensuring long-term stability in operational environments.
Low Moisture Content (<1 wt.%): Prevents agglomeration during storage and processing, ensuring uniform dispersion in slurries or composite electrodes (e.g., with GDC electrolytes)—essential for consistent performance.
Balanced Co/Ni Ratio: The 0.6 Co : 0.4 Ni ratio optimizes oxygen ion conductivity (from Co) and thermal/chemical stability (from Ni), reducing degradation under cyclic operation compared to cobalt-rich perovskites.
Perovskite Structural Stability: Retains its ABO₃ crystal structure under oxidizing atmospheres, with minimal phase decomposition at operating temperatures—ensuring durability in IT-SOFC stacks.
High Electronic Conductivity: Exhibits p-type conductivity (100–300 S/cm at 700°C), facilitating efficient electron transport in cathode layers and reducing polarization resistance.
Core Applications
Intermediate-Temperature Solid Oxide Fuel Cells (IT-SOFCs)
LCN164 is engineered for high-performance IT-SOFC cathodes, where activity and stability are paramount:
Cathode Layers: Delivers exceptional ORR activity at 600–750°C, a temperature range that reduces material degradation and lowers system costs compared to high-temperature SOFCs.
Composite Cathodes: Blends seamlessly with electrolytes like GDC (gadolinium-doped ceria) to form functional gradients, optimizing ion conduction and minimizing interfacial resistance.
Small-Scale Power Systems: Supports compact IT-SOFC designs for portable or distributed power generation, leveraging its balance of activity and durability.
Oxygen Sensing & Catalysis
Oxygen Sensors: Functions as a sensing electrode in high-temperature oxygen sensors, leveraging its sensitivity to oxygen partial pressure and stable electrical response.
Oxidation Catalysis: Catalyzes reactions such as CO oxidation and volatile organic compound (VOC) degradation, supported by its redox-active Co³⁺/Co⁴⁺ and Ni²⁺/Ni³⁺ sites.
