一般描述

LSC-82 is a promising cathode material for Solid Oxide Fuel Cells with a pervoskite type structure.
LSC-82 has the unique ability to reduce itself reversibly at moderate partial pressures of oxygen, thus producing large numbers of oxygen ion vacancies. The ion vacancies allow a number of events to take place, such as;
  • ease the transport of oxygen ion and cause oxygen surface exchange,
  • raise mechanical stress by causing volume expansion of the lattice.
Influence of change in temperature on the properties of LSC-82 has been reported in detail. Effect of temperature on magnetic susceptibility has also been reported.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

应用

SOFCs containing LSC-82 cathodes show good performances with doped ceria electrolytes compared to yttria stabilized zirconia electrolytes.
