HYDROGEN PURIFICATION SEPARATION MEMBRANE MODULE AND METHOD FOR SEALING HYDROGEN SEPARATION MEMBRANE

摘要

PURPOSE: A hydrogen purification separating membrane module and a method for sealing a hydrogen separating membrane in the module are provided to suppress the diffusion of a hydrogen separating membrane and seal by forming a diffusion suppressing layer at the contact side of the hydrogen separating membrane and the seal. CONSTITUTION: A hydrogen purification separating membrane module includes a lower flange(40), a porous support(20), a hydrogen separating membrane(10), an upper flange(30), and internal seal(50). The lower flange includes a loading groove(41), a supporting protruded part(44), and a hydrogen through hole. The porous support is arranged in a space which is defined by the loading groove and the supporting protruded part. The hydrogen separating membrane is supported by the porous support. The hydrogen separating membrane is palladium, or the mixture or the alloy of palladium and one or more metal components selected from Co, Ag, Au, Ru, and Pt. The upper flange is combined with the lower flange. A diffusion suppressing layer is arranged at the contact side of the hydrogen separating membrane and the inner seal.
