“…In recent years, perovskite and its derived structures play an important role in SOFC electrode research. [22][23][24][25][26][27][28][29][30][31] Perovskite and its derivative systems are used in classical cathode materials. LaSr(MnO 3 ) 2 , as the representative material of cathode, has good physical properties, cathode stability and electrode performance above 1000°.…”
