Outline of Final Research Achievements	An amorphous silica based membrane consists of a porous support, a mesoporous intermediate layer and sub-nano ordered active layer. Therefore, we have to optimize the whole membrane structure and the concurrent improving of H2 permeance and H2 permselectivity is difficult. We have developed the SiO2 membrane with high H2 permeance and high H2 permselectivity by using a counter diffusion chemical vapor deposition. The high H2 permselective membrane was obtained to be higher the possibility which source gas and oxygen gas reacted in mesoporous intermediate layer.
