Phosphate-based molten salts are identified as potential electrolytes for the high temperature electrolysis of water and for possible use in the Lithium Hydride Thermochemical Cycle. The behavior of polymeric, partially neutralized phosphoric acid is observed with respect to its thermal stability, ability to receive steam, and its corrosiveness to potential electrode materials. The results of these tests are favorable and warrant further, more quantitative studies of the suitability of phosphate melts as electrolytes for water electrolyis.
