Hydrogen separation membrane consisted of Silicon Carbide(SiC) thin fim and a SiC intermediate layer was prepared. The intermediate layer was deposited on a porous alumina support by a pylorisis after a coating of the SiC precursor film, an immersion of the film in a solvent and a curing. Maximum hydrogen permeanse and selectivity of the membrane with the "immersed" intermediate layer at 523.15 K was larger than that of the membrane with "un-immersed" layer.
