In the IS process, the improvement of efficiency and the downsizing can be achieved if equilibrium inversion rate of HI decomposition is improved by using membrane reactor with hydrogen separation membrane. In this paper, the application to the silica hybrid membrane prepared by counter diffusion CVD method was investigated. As a result, we can obtain the H $_{2}$ /HI permeation rate, 6820 and the H $_{2}$ permeance, 5.010 $^{-7}$ mol m $^{-2}$ s $^{-1}$ Pa $^{-1}$ at 400 $^{circ}$ C, indicating that this membrane can be applied to this system. In addition, relation between SF $_{6}$ and HI permeance of membrane was investigated and verified to show the positive correlation. This result indicates that HI permeance of membrane can be evaluated by using SF $_{6}$ permeance, which can be easily treated.
