{"product_id":"csofecceplsm8ysz","title":"LSM\/8YSZ Composite Electrode Powder for SOFC\/SOEC, 100 g\/bottle, CSOFECCEPLSM8YSZ","description":"\u003cp\u003eIn Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC), LSM\/8YSZ composite powder is the foundational \"air electrode\" material. While pure LSM is an excellent electronic conductor, it has very low ionic conductivity. Mixing it with 8 mol% Yttria-Stabilized Zirconia (8YSZ) transforms the electrode from a simple surface-active layer into a high-performance, three-dimensional reaction zone. The composite is particularly favored for high-temperature systems (750 °C–1000 °C) because it is chemically stable, mechanically robust, and eliminates the need for expensive barrier layers.\u003c\/p\u003e\n\u003cp\u003eIn a pure LSM electrode, the Oxygen Reduction Reaction (ORR) can only happen at the Triple Phase Boundary (TPB)—the exact line where the gas, the electronic conductor (LSM), and the electrolyte (YSZ) meet. This severely limits the reaction area. (1)\u003cstrong\u003e Ionic Highways\u003c\/strong\u003e: By adding 8YSZ particles into the LSM matrix, you create a network of \"ionic highways\" that extend into the bulk of the electrode.
