ANODE MATERIAL FOR SOLID OXIDE FUEL CELL, ANODE STRUCTURE FOR SOLID OXIDE FUEL CELL HAVING THE ANODE MATERIAL, AND SOLID OXIDE FUEL CELL HAVING THE ANODE STRUCTURE

摘要

The present invention provides an anode material having excellent thermochemical stability and high electric conductivity. The anode material, according to one embodiment of the present invention, comprises a compound represented by chemical formula 1 (RE_1-xE^_xT_2O_5+). The R comprises one or more elements selected from a rare-earth group or a lanthanum group; the E and E^ comprise different elements selected from alkali earth metals; and the T comprises one or more elements selected from transition metals. O is oxygen; the x is greater than 0 and less than 1; and the is a positive number of less than or equal to 0 or 1 and is a value satisfying electroneutrality in a compound of the chemical formula 1.
