Fuel cell, high-temperature molten salt solid electrolyte

If the materials and corrosion problems are solved high temperature fuel cells could be used in the framework of a hydrogen economy for the conversion of hydrogen into electric energy. Cells with molten salt electrolytes immobilized in a ceramic matrix could be applied at 850-950 K and with solid oxygen ion conducting electrolytes at 1200-1300 K. 

Roughly fuel cells can be classified into low-temperature (operation temperature below 500 °C) and high-temperature (operation temperature up to 1,000 °C) cells [13]. As electrolytes molten salts or ionically conductive solids are used. Concerning the fuels, electrodes, electrolytes, and constructive details, in recent years a variety of different fuel cells of both types have been developed, e.g., ...
