Patent

CA 2406207

A hydrogen-permeable structure which comprises a porous support and, formed on the surface or in the interior thereof, a hydrogen-permeable membrane comprising palladium (Pd) and having a thickness of 2 µm or less; a method for manufacturing the hydrogen-permeable structure which comprises supplying a solution containing Pd from one side of the porous support and a reducing material from the other side thereof, to thereby form the hydrogen-permeable membrane on the surface or in the interior of the porous support. The hydrogen- permeable structure is improved in the prevention of release of a hydrogen- permeable membrane and thus exhibits improved durability.

L'invention concerne une structure perméable à l'hydrogène qui comprend un support poreux, et sur la surface ou à l'intérieur de ce dernier, une membrane perméable à l'hydrogène comprenant du palladium (Pd) et présentant une épaisseur inférieure ou égale à 2 ?m. L'invention traite d'un procédé pour fabriquer la structure perméable à l'hydrogène qui consiste à fournir une solution contenant du Pd à partir d'un côté du support poreux et un matériau réducteur à partir de l'autre côté de ce dernier. On obtient ainsi la membrane perméable à l'hydrogène sur la surface ou à l'intérieur du support poreux. La structure perméable à l'hydrogène est améliorée et empêche le retrait de la membrane perméable à l'hydrogène et présente une meilleure durabilité.
