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

摘要

LSM(La(Sr)MnO_3)/YSZ(Y_2O_3 stabilized ZrO_2) 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 800 ℃. It suggests that the intermediate temperature (less than 800 ℃) operation of SOFCs will be achieved by using composite particles.
