The research and development program of the IS process using the membrane technology and solar heat is now on progress aiming at improvement of the hydrogen production efficiency up to 40%. In the HSO decomposition reaction process, oxygen production process, the decomposition rate of sulphur trioxide (SO) is expected more than 80% at the reaction temperature of 800 - 900C. On the other hand, the decomposition rate of SO decreases to around 30% in the reaction temperature of 600C which temperature will be provided by solar heat, ceramic oxygen permselective membrane and catalyst have been developing to promote SO decomposition in the reaction temperature of 600C. In addition, the ceramic hydrogen permselective membrane and catalyst to promote HI decomposition for hydrogen production, the cation-exchange membrane and catalyst to reduce amount of iodine in the HI circulation process. Also, the corrosion-resistance material to use metal components in the HSO decomposition process is underway.
