Hydrogen is considered a fuel of the future due to its diversified supply and zero greenhouse gas emission. The application of advanced membrane technology for hydrogen separation within the larger hydrogen production process context can substitute the use of more expensive and energy intensive cryogenic distillation and pressure swing adsorption technologies. This review overviews the basic aspects and progresses in perovskite-based proton conducting hydrogen separation membranes. Different configurations such as symmetric, asymmetric, hollow fiber, and surface modified perovskite membranes with various compositions are discussed and summarized. The challenges and future directions of such membranes are also elaborated.

氢由于其多样化的供应和零温室气体排放而被认为是未来的燃料。在更大的制氢工艺范围内应用先进的膜技术进行氢分离可替代使用更昂贵且耗能大的低温蒸馏和变压吸附技术。这篇综述概述了钙钛矿基质子传导氢分离膜的基本方面和进展。讨论并总结了不同的配置，例如对称，不对称，中空纤维和具有各种成分的表面改性钙钛矿膜。还阐述了这种膜的挑战和未来的方向。
