Insights on perovskite-type proton conductive membranes for hydrogen permeation.

Hydrogen has received widespread attention because as its diverse delivery methods and no GHG emissions. The use of membrane separation can effectively replace the costly low-temperature distillation and pressure swing adsorption technology to achieve the purpose of low-cost hydrogen enrichment. As a promising hydrogen separation material, perovskite-type proton conductor hydrogen permeable membrane has been practically applied in hydrogen separation and purification process. In this paper, the principle of hydrogen permeability of perovskite-type proton conductor hydrogen permeable membrane is expounded, and its preparation method and application are summarized, and the development trend of the material is discussed. [Display omitted] • Perovskite oxides are the prominent materials for hydrogen transport. • Hydrogen conduction mechanism of perovskite oxides was discussed. • Preparation methods of perovskite oxide permeable materials were summarized.
