| Abstract: | The La-Bi-Al-O and La-Bi-Al-Zn-O series were prepared by solid synthesizing method.The phase compositions of the obtained products were determined by X-ray diffraction. The results show that the La-Bi-Al-O series are composed of LaAIO3, BiAIO3 and AlyBiZOg. In La-Bi-Al-Zn-O series, Zn2 can be doped into the crystal lattice of LaAIO3 and BiAIO3, and the conductivity can be enhanced by the doped Zn2 . A solid oxide fuel cell was prepared by using LaBi-ALZn-O as electrolyte, and its i- U curve was determined. The open, voltage of the fuel cellis about 0. 6 V and the short current density is about 50 mA.cm-- 2. |
