Research and technology studies on molten carbonate fuel cells (MCFCs) are being directed at improving their performance for greenhouse gas conversion for chemical energy storage. Changes in the composition of the gas feeding MCFCs need new stable insulating material compositions. In this work, magnesia ceramics is subjected to corrosion tests in the eutectic carbonate melts Li2CO3–Na2CO3 and Li2CO3–K2CO3 at 600°C for 270 h. Magnesia MgO is shown to exhibit low solubility in the molten alkali-metal carbonate salts and a high chemical stability. Conclusions about the stability of the material are based on results of elemental analysis of the melts, X-ray diffraction analysis, and scanning electron microscopy. Magnesia ceramics can be recommended as an insulating material for a molten electrolyte in chemical energy storage devices operating as greenhouse gas converters in air. [ABSTRACT FROM AUTHOR] |
