AIR ELECTRODE FOR SOLID OXIDE FUEL BATTERIES, AND SOLID OXIDE FUEL BATTERY CELL
PROBLEM TO BE SOLVED: To provide an air electrode for solid oxide fuel batteries which is arranged by use of a novel material.SOLUTION: An air electrode for solid oxide fuel batteries comprises an apatite type oxide expressed by the following general formula (1): (LnA)(SiBM)O. (In the formula (1), 0≤X≤2.0; 0≤Y≤3.0; X+Y>0; 0<β≤3.0; Y+β≤4.0; Ln includes at least one of La, Pr and Nd; A includes at least one of Mg, Ca, Sr and Ba; B includes at least one of Mg, Fe, Al, B, Ga, Ge and P; and M includes at least one of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Ta and W.) It is particularly preferable that the apatite type oxide is an oxide expressed by La(SiAlRu)O.
