Description
Lanthanum Strontium Cobaltite (LSC) is a highly conductive perovskite material that is often used as an electrode or contact paste in SOFC systems, where it creates the bond between the cathode of the cell and the current collector (often a metal mesh or plate). This LSC powder can be easily fabricated into an ink for painting or screen printing. LSC has a relatively low sintering temperature, so it is best used in SOFCs operating at less than about 750 °C. Another design consideration for using LSC is its relatively high thermal expansion coefficient, which leads to expansion mismatches at higher operating temperatures.
