(La0.8Sr0.2)0.95MnO3/Yttria Stabilized Zirconia 복합체 전극을 이용한 고온 수증기 전기분해 연구

고온수증기 전기분해의 양극물질로 이용될 수 있는 (La0.8Sr0.2)0.95MnO3/yttria-stabilized zirconia(LSM/YSZ) 복합체 전극을 x-ray diffractometry, scanning electron microscopy 그리고 galvanodynamic, galvanostatic polarization method 로 연구하였다. 이런 목적으로 perovskite-type의 LSM 물질은 공침법을 이용하여 제조하였으며, 8 mol％ YSZ와 몰분 율을 달리하여 복합체 전극을 합성하였다. LSM/YSZ 복합체 전극은 평판의 YSZ 전해질에 LSM/YSZ 복합체를 스크린 프린팅 후 1,100 ℃에서 열처리 코팅하여 제조하였다. 실험결과로부터 LSM/YSZ 복합체 전극의 전기화학적 특성 은 전극을 이루는 삼상계면의 구조와 전기분해 온도에 영향을 받는다는 것을 확인하였다.
The (La0.8Sr0.2)0.95MnO3/yttria-stabilized zirconia (LSM/YSZ) composites were investigated as anode materials for high temperature steam electrolysis using X-ray diffractometry, scanning electron microscopy, galvanodynamic and galvanostatic polarization method. For this purpose, the LSMperovskites were fabricated in powders by co-precipitation method and then were mixed with 8 mol％ YSZ powders in different molar ratios. The LSM/YSZ composites were deposited on 8 mol％ YSZ electrolyte disks by means of a screen printing method, followed by sintering at temperatures above 1,100 ℃. From the experimental results, it is concluded that the electrochemical properties of LSM and the LSM/YSZ composites are closely related to their microstructure and operating temperatures.
