Abstract

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.
