Title (EN) COMPOSITE OXYGEN ION TRANSPORT MEMBRANE
(FR) MEMBRANE DE TRANSPORT D’ION OXYGÈNE COMPOSITE
Abstract:
(EN) A composite oxygen ion transport membrane having a dense layer, a porous support layer, an optional intermediate porous layer located between the porous support layer and the dense layer and an optional surface exchange layer, overlying the dense layer. The dense layer has electronic and ionic phases. The ionic phase is composed of scandia doped, yttrium or cerium stabilized zirconia. The electronic phase is composed of a metallic oxide containing lanthanum, strontium, chromium, iron and cobalt. The porous support layer is composed of zirconia partially stabilized with yttrium, scandium, aluminum or cerium or mixtures thereof. The intermediate porous layer, if used, contains the same ionic and electronic phases as the dense layer. The surface exchange layer is formed of an electronic phase of a metallic oxide of lanthanum and strontium that also contains chromium, iron and cobalt and an ionic phase of scandia doped zirconia stabilized with yttrium or cerium.
(FR) La présente invention concerne une membrane de transport d’ion oxygène composite ayant une couche dense, une couche de support poreuse, une couche poreuse intermédiaire facultative située entre la couche de support poreuse et la couche dense et une couche d'échange de surface facultative, recouvrant la couche dense. La couche dense a des phases électronique et ionique. La phase ionique est composée de zircone dopée avec de l’oxyde de scandium, stabilisée avec de l’yttrium ou du cérium. La phase électronique est composée d'un oxyde métallique contenant du lanthane, du strontium, du chrome, du fer et du cobalt. La couche de support poreuse est composée de zircone partiellement stabilisée avec de l'yttrium, du scandium, de l'aluminium ou du cérium ou des mélanges de ceux-ci. La couche poreuse intermédiaire, si elle est utilisée, contient les mêmes phases ionique et électronique que la couche dense. La couche d'échange de surface est formée d'une phase électronique d'un oxyde métallique de lanthane et de strontium qui contient également du chrome, du fer et du cobalt et d'une phase ionique de zircone dopée avec de l'oxyde de scandium stabilisée avec de l’yttrium ou du cérium.
