CA 2422667

A sealing technique is established in which a seal can be easily formed and which is excellent in reliability and a heat cycle property in a high temperature region of 800 °C or higher, so as to provide a composite body preferably used for a device for producing pure oxygen, oxygen-rich air, and the like, a membrane reactor represented by that for partial oxidation of a hydrocarbon gas, a solid oxide fuel cell, an oxygen purification device, a heat exchanger, or the like. The present invention makes it possible to increase a possibility of practical use in a wide area which has been delayed in development owing to a bottleneck of improvement in a sealing property. Particularly, its application to the device for producing pure oxygen, oxygen-rich air, or the like, the membrane reactor represented by that for partial oxidation of the hydrocarbon gas, the solid oxide fuel cell, the oxygen purification device, the heat exchanger, or the like can greatly contribute to acceleration of the development.

La présente invention concerne un article composite qui comprend une partie étanche, pouvant facilement être produite dans une région à haute température de 800 DEG ou plus, est très fiable et présente des caractéristiques très satisfaisantes lors de cycles thermiques. Cet article composite est par conséquent adapté à un usage dans un appareil de production d'oxygène pur, d'air enrichi en oxygène ou d'un gaz similaire, dans un réacteur à membrane barrière, représenté par celui permettant une oxydation partielle d'un hydrocarbure gazeux, une pile à combustible à oxyde solide, un appareil de purification d'oxygène gazeux, un échangeur thermique ou un appareil similaire. L'article composite selon cette invention permet d'améliorer la possibilité de commercialisation d'appareils dont le développement a connu un retard du à une étanchéification insatisfaisante, dans une vaste gamme d'applications. L'utilisation dudit article composite dans les appareils susmentionnés peut notamment favoriser de façon considérable l'accélération de leur développement.
