▎ 摘　　要

NOVELTY - A system for separation of hydrogen isotopes from one another, comprises: 1) a separation device (20) containing a feed chamber, a product chamber and a separation membrane (10) forming a gas-tight seal between the feed chamber (2) and the product chamber (4), the separation membrane contains a hydrogen isotope selective layer (14) and a hydrogen ion conductive layer (12), the hydrogen isotope selective layer comprises a crystalline material, and the hydrogen ion conductive layer comprises a hydrogen ion conductive ceramic, the separation membrane comprises a first side facing the feed chamber and an opposite second side facing the product chamber; an electric circuit in electrical communication with the separation membrane and configured to apply a voltage between the first side and the second side of the separation membrane; and 2) a heater configured to increase the temperature of the separation membrane. USE - System is used for separating hydrogen isotopes from one another. ADVANTAGE - The system enables to separate hydrogen isotopes from one another, without the need for an aqueous-based system. The stable and durable system enables to achieve high isotope selectivity, utilizing hydrogen isotope selective separation membrane. An electronic driving force encourages passage of isotopes selectively across the membrane at an elevated separation temperature, to enrich the product in a selected hydrogen isotope.
