The unusually high solubilities and thermal coefficients of solubility of the alkali metal hydroxides make them attractive candidates for high-temperature electrolytic processes to produce high-pressure hydrogen. The feasibility of using strong sodium hydroxide (to keep down the saturation pressure of the condensed phase) electrolysis (to facilitate the separation of the hydrogen from oxygen over a liquid phase) at high temperatures (to increase the energy efficiency by substitution of process heat for electric power) and to increase the production rate in a given cell (by increasing the specific conductance of the working fluid) is explored and discussed. Suggestions are made for future research.
