Title:
固体酸化物形燃料電池用空気極材料
Document Type and Number:
Japanese Patent JP5044392
Kind Code:
B2
Abstract:
This invention provides an air electrode material for a fuel cell, which is superior in electrode activity persistence to conventional materials and has durability high enough to withstand even repeating heat history between room temperature during stop of the operation and a high temperature above 700ºC during operation. The air electrode material for a solid oxide fuel cell is characterized by comprising a perovskite oxide represented by general formula (I): (PrxA1-x)(FeyB1-y)O3 ······ (I) wherein A represents an alkaline earth metal element or the like; B represents a group 7a element or the like; x is 0.5 = x = 1; and y is 0.5 = y = 1.
