Abstract
A connected body including a gas separator 10 and metallic members 21 and 22, each of which has a partly oxidized surface to be reliably connected with the gas separator. The gas separator includes a ceramic substrate 11 and a gas separation membrane 12 to be coated onto substrate 11. The substrate 11 is porous so that a gas molecule can pass therethrough, and gas separation membrane 12 is connected with metallic members 21 and 22 by a glass 15 having a thermal expansion coefficient of 5.0-8.0.times.10.sup.-6 /.degree.C. Glass 15 contacts with metal supporters 21 and 22 with a contact angle of 90.degree. or less. The connected body of a gas separator and metallic supporters and an apparatus for separating hydrogen gas from a mixed gas display excellent durability and are free from leakage at the joints during the separation of hydrogen gas at high temperatures and under high pressure.
