Heat resistant hydrogen separation membrane and method for manufacturing same

摘要

The present invention relates to a hydrogen separation membrane which coats granular ceramic onto the surface of a porous metal support and which coats a hydrogen permeation metal thereon so as to inhibit diffusion between the support and a hydrogen separation layer, and to a method for manufacturing same. As a result, the metal support can be modularized with ease, the hydrogen permeation layer can be made thinner to increase the amount of hydrogen permeation, the use of a separation material can be minimized, and the hydrogen separation membrane can have higher competitiveness.

主权项

1. A hydrogen separation membrane comprising:
a porous metal support; an interdiffusion barrier which is prepared by coating a surface of the porous metal support with a mixture of ceramics and metals in a column shape perpendicular to the surface of the porous metal support; and a dense hydrogen separation layer which is applied on the interdiffusion barrier wherein the dense hydrogen separation layer comprises at least one selected from the group consisting of Cu, Ag, Ni, Au, Ru, Rh, Nb, Ta, V, Cr, Al, Y and Ga.
