In both Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC), LSC (Lanthanum Strontium Cobaltite) is a high-performance perovskite material—typically La0.6Sr0.4CoO3-δ or La0.8Sr0.2CoO3-δ. While LSCF (the Iron-doped version) is the standard for intermediate-temperature cathodes, LSC is used when maximum electrical conductivity and high catalytic activity are required, often as a contact layer or in high-performance "thin-film" cells.
In SOFC/SOEC stacks, the most common use for LSC powder is as a "Contact Paste" or "Current Collection Layer." (1) Bond: LSC is applied between the main cathode (like LSCF or LSM) and the metallic interconnect (stainless steel plate). (2) Low Resistance: Because LSC is nearly 5\times more conductive than LSCF, it minimizes the ohmic losses at the interface where current must travel from the cell into the stack manifold. (3) Low-Temp Sintering: LSC can be sintered as low as 800 °C, which allows it to form a strong electrical bond without damaging the pre-sintered cell or causing excessive chromium evaporation from the interconnects.
