ABSTRACT:
A compact hydrogen purification module capable of affording high-grade purified hydrogen, easy assembly and easy control of size is disclosed. The module includes a plurality of unit cells. Each of the unit cells includes two metal membranes permeable only by hydrogen, a metal support ring attached between the metal membranes by diffusion bonding to support the metal membranes, and having a radial hole to allow hydrogen to flow therethrough, a porous plate disposed between the metal membranes to allow the hydrogen to flow therethrough, and a fitting coupled to the metal support ring and having a hole communicating with the hole of the metal support ring to allow the hydrogen to flow therethrough. The individual fittings are connected to each other so that hydrogen collected in the individual fittings is discharged through a hydrogen product line.
