A new thermochemical hybrid hydrogen production process is under investigation to realize the hydrogen production from water by using the heat generation of coolant of sodium in Fast Breeding Reactor (FBR). Newly proposed cycle is based on sulfuric acid (H2SO4) synthesis and the decomposition processes developed earlier, and SO3 decomposition process at about 500°C is facilitated by electrolysis with ionic oxygen conductive solid electrolyte which is extensively utilized for high-temperature electrolysis of water. Measured decomposition voltage of sulfur trioxide (SO3) with 8mol yttria stabilized zirconia (8molYSZ) solid electrolyte and platinum electrode were lower than 0.5V at 500°C-600°C, and oxygen permeation rate through YSZ into N2 purge gas agreed well with the calculated permeation rate from measured cell current. Preliminary measured oxygen permeation rate through La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) in air supplied experiments were higher than the rate through 8molYSZ. These results show the possibility of development of higher performance electrolytic cell using other solid electrolytes than YSZ. Thermal efficiency of the proposed cycle based on chemical reactions was 47.3% with no heat recovery.
