基于闪光烧结薄膜Y:BaZrO₃-δ电解质的全溅射质子陶瓷燃料电池，这一成果由anonymous研究团队经过不懈努力而取得。这一研究成果于2025年4月9日发表在国际顶尖学术期刊《结构化学》上。

在这项工作中，课题组提出了一种结合磁控溅射和手电筒烧结技术制造高性能质子传导陶瓷燃料电池（PCFCs）的创新方法。在保持化学计量的同时，提高了结晶度，成功制备了BaZr_0.8Y_0.2O_3-δ (BZY20)电解质薄膜。PCFC的所有组件，Ni-YSZ阳极，BZY20电解质和Pt-GDC阴极，都是通过顺序溅射在AAO衬底上制备的。在550 V和650 V条件下进行电解烧结，有效地解决了传统热烧结方法中钡的蒸发问题。XRD分析证实，FLS样品保留了钙钛矿结构，结晶度得到改善。

此外，FE-SEM和EDS分析证实了fls处理后的电解液元素分布均匀，厚度一致。在500℃时，经FLS处理的PCFC单体电池的峰值功率密度为200.0 mW cm^-2，欧姆电阻为376.0 mΩ cm^-2。这些结果表明，磁控溅射和FLS技术的结合是制备高性能薄膜PCFCs的一种很有前途的方法。

Abstract: In this work, we present an innovative method for fabricating high-performance proton-conducting ceramic fuel cells (PCFCs) by combining magnetron sputtering and flashlight sintering (FLS) techniques. BaZr0.8Y0.2O3-δ (BZY20) electrolyte thin films were successfully prepared by improving the crystallinity while maintaining the stoichiometry. All components of the PCFC, the Ni-YSZ anode, BZY20 electrolyte, and Pt-GDC cathode, were fabricated by sequentially sputtering them onto an AAO substrate. Electrolytic sintering was performed at 550 V and 650 V conditions using FLS, effectively solving the barium evaporation problem encountered in conventional thermal sintering methods. XRD analysis confirmed that the perovskite structure was retained, and crystallinity was improved in the FLS samples. Furthermore, FE-SEM and EDS analyses confirmed the uniform elemental distribution and consistent thickness of the FLS-treated electrolyte. An optimized PCFC unit cell with FLS-treated electrolyte exhibited a peak power density of 200.0 mW cm-2 at 500 °C and an ohmic resistance of 376.0 mΩ cm-2. These results suggest that the combination of magnetron sputtering and FLS techniques is a promising approach for fabricating high-performance thin-film PCFCs.
