| 简介 |
PURPOSE : A positive electrode material for fuel cell is provided to reduce polarization resistance of a positive electrode for a solid oxide fuel cell, thereby capable of maintaining low electrode resistance in low temperatures lower than 800 °C, and restraining performance degradation of an electrode.
CONSTITUTION : A positive electrode material for fuel cell comprises a lanthanum based metal oxide perovskite type crystal structure, and a bismuth based metal oxide in chemical formula 1 : Bi_(2-x-y)A_xB_yO_3. In chemical formula 1 A and B is independently and respectively trivalent metal selected from rare earth metal, lanthanum based metal, and transition metal, A and B are different each other, and 0
