The paper studies the performance of the intermediate temperature solid oxide fuel cells with the sputter deposited La₁-_xSr_xCoO₃ (LSC) interlayer between the cathode and electrolyte. The sputter deposition of the LSC thin films is carried out in argon gas and in a mixture of argon and oxygen gases and then are annealed at 600, 800 and 1000 °C in air for 2 h. The structure and composition of the sputter deposited LSC films are investigated by the X-ray diffraction analysis, scanning and transmission electron microscopies, and energy-dispersive X-ray spectroscopy. The polarization resistance of the sputter deposited LSC films (600 nm thick) on the symmetric cells is 0.13, 0.45 and 2.48 Ohm·cm² measured at 800, 700 and 600 °C, respectively. Measurements are performed by electrochemical impedance spectroscopy. The maximum power density of the anode-supported solid oxide fuel cells with the yttria-stabilized zirconia/gadolinia-doped ceria bilayer electrolyte, LSC interlayer, and LSC cathode is 2.27, 1.58 and 0.68 W/cm² measured at 800, 700 and 600 °C, respectively. These values of the power density are respectively 1.4, 1.6 and 2.3 times higher than that of the reference cell without the LSC interlayer.

本文研究了在阴极和电解质之间具有溅射沉积的La ₁ - _x Sr _x CoO ₃（LSC）中间层的中温固体氧化物燃料电池的性能。LSC薄膜的溅射沉积是在氩气中以及在氩气和氧气的混合物中进行的，然后在600、800和1000°C的空气中退火2小时。通过X射线衍射分析，扫描和透射电子显微镜以及能量色散X射线光谱研究了溅射沉积的LSC膜的结构和组成。对称池上溅射沉积的LSC膜（厚600 nm）的极化电阻为0.13、0.45和2.48 Ohm·cm ^2。分别在800、700和600°C下测量。通过电化学阻抗谱进行测量。在800、700和600下测得的具有氧化钇/氧化d掺杂的二氧化铈双层电解质，LSC中间层和LSC阴极的阳极支撑固体氧化物燃料电池的最大功率密度为2.27、1.58和0.68 W / cm ²。分别为℃。这些功率密度值分别是没有LSC中间层的参考电池的1.4倍，1.6倍和2.3倍。
