Title (EN) COMPOSITE MIXED OXIDE IONIC AND ELECTRONIC CONDUCTORS FOR HYDROGEN SEPARATION
(FR) CONDUCTEURS ELECTRONIQUES ET IONIQUES MIXTES, COMPOSITES, A L'OXYDE, POUR LA SEPARATION DE L'HYDROGENE
Abstract: front page image
(EN)A mixed ionic and electronic conducting membrane includes a two-phase solid statec ceramic composite, wherein the first phase comprises an oxygen ion conductor and the second phase comprises an n-type electronically conductive oxide, wherein the electronically conductive oxide is stable at an oxygen partial pressure as low as 10-20 atm and has an electronic conductivity of at least 1 S/cm. A hydrogen separation system and related methods using the mixed ionic and electronic conducting.
(FR)L'invention concerne une membrane à conduction électronique et ionique mixte comprenant un composite en céramique à l'état solide, diphasique, la première phase comprenant un conducteur d'ions oxygène et la seconde phase comprenant un oxyde conducteur d'électrons de type n. Cet oxyde conducteur d'électrons est stable à une pression partielle de l'oxygène aussi basse que 10-20 atm et possède une conductivité électronique d'au moins 1 S/cm. L'invention concerne également un système de séparation d'hydrogène et des procédés associés dans lesquels est utilisé cette membrane à conduction électronique et ionique mixte.
