AIR ELECTRODE MATERIAL FOR LOW TEMPERATURE ACTION TYPE SOLID FUEL CELL

摘要

PURPOSE:To provide an air electrode for low-temperature action type solid fuel cell for satisfying two requirements consisting of electrical characteristics and stability of micro structure under action temperature at the same time. CONSTITUTION:In air electrode materials for forming the air electrode of a low-temperature action type solid fuel cell, the above air electrode is set to a mixture of one kind selected from zirconia, alumina, and lanthanide series pyrochlore, and a copper oxide of K2NiF4 structure with the volume mixture rate of 1:9 or 7:3. Chemically inactive oxide is dispersed in perovskite type copper oxide of K2NiF4 structure so that the air electrode which prevents sintering under action temperature and holds porous state suited for air supply can be provided.
