In both Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC), LSCF (Lanthanum Strontium Cobalt Ferrite) is the primary material for the "Intermediate Temperature" oxygen electrode. Typically formulated as La0.6Sr0.4Co0.2Fe0.8O3-δ, it is a Mixed Ionic-Electronic Conductor (MIEC).
The behavior of LSCF varies based on the current direction, making it a "reversible" electrode material: (1) SOFC Mode (Fuel Cell): It acts as the cathode, facilitating the Oxygen Reduction Reaction (ORR). Because LSCF is an MIEC, the reaction area extends across the entire surface of the electrode grains, allowing for much higher power densities at lower temperatures compared to LSM. (2) SOEC Mode (Electrolysis): It acts as the anode, facilitating the Oxygen Evolution Reaction (OER). LSCF is highly efficient for electrolysis but faces greater mechanical stress in this mode due to high local oxygen partial pressures (pO2) at the electrode/electrolyte interface.
