Morphology control of the electrode for Solid Oxide Fuel Cells by using nanoparticles

LSM(La(Sr)MnO3)/YSZ(Y2O3 stabilized ZrO2) composite cathode for Solid Oxide Fuel Cells (SOFCs) was fabricated by using the composite particle consisting of well-dispersed nano-size grains of LSM and YSZ. The composite cathode had a porous structure as well as uniformly dispersed fine LSM and YSZ grains. Such unique morphology of the composite cathode led high electrochemical activity at 800degreesC. It suggests that the intermediate temperature (less than 800degreesC) operation of SOFCs will be achieved by using composite particles.
