<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an air electrode material for a solid oxide fuel cell, wherein the air electrode material having fewer unreacted phases and intermediate generated phases can be manufactured more efficiently. <P>SOLUTION: The manufacturing method mixes and calcinates raw materials of an air electrode material for a solid oxide fuel cell (steps S1 and S2), and holds the raw materials during second time at second temperature lower than first temperature after holding the raw materials during first time at first temperature (step S3), repeating the above steps by the predetermined number of times. This can manufacture the air electrode material having fewer unreacted phases and intermediate generated phases more efficiently. <P>COPYRIGHT: (C)2010,JPO&INPIT |
