Development of Water Electrolysis Cell for Hydrogen Production UtilizingSulfur Dioxide

Water electrolysis utilizing sulfur dioxide is attractive for low-electricity-consumption hydrogen production and has been investigated for the electrolytic and thermochemical hybrid hydrogen production process utilizing the heat generated by a nuclear power plant. In this study, the hydrogen production performance of the water electrolysis cell utilizing sulfur dioxide gas and the sulfur dioxide crossover prevention performance of several polymer electrolytes were investigated experimentally.
