<p>The present invention relates to a hydrogen separation membrane and a preparation method therefor, and the purpose thereof is to provide a hydrogen separation membrane while having high corrosion resistance to a sulfur compound contained in synthetic gases (H2+CO) and capable of minimizing a decrease in hydrogen permeability. The hydrogen separation membrane according to the present invention comprises: a porous support; a buffer layer, which is made from a ceramic material, formed on the porous support; a palladium-based metal separation membrane formed on the buffer layer and capable of separating hydrogen; and a protective layer, which is made from a metal or ceramic material, formed as a plurality of columns on the metal separation membrane.</p> |
