Cathode Materials for Intermediate Temperature Solid Oxide Fuel Cells

Abstract

The development of solid oxide fuel cell has been extensively performed from both industrial and experimental points of view. La0.80Sr0.20MnO3 has proven to be unsuitable for use < 800°C due to very low oxygen vacancy concentration. In light of this, the oxygen vacancy level was determined from electrical conductivity, TGA, and neutron diffraction. A large decrease in 3-δ was observed when the gas was changed from 90 to 99% CO. La0.80Sr0.20MnO3 decomposed in the 99% CO atmosphere. The consistence results between TGA and neutron diffraction confirmed that the quenching experiment could be used to study the ferrites under reducing conditions.
