摘要
Solid electrolytes(CeO2)0.7-x(MO)x (La2O3) 0.3(M = Mg,Ca,Sr)were synthesized.Their crystal structure,conductivity, XPS spectrum,ionic transferance number and the V-1 curve of the obtained fuel cell were measured.(CeO2)0.7z (La2O3)0.3 doped with Ca2+,Mg2+,and Sr2+can perform the oxygen ionic electrolyte,and so enhance the open voltage and power output of the fuel cell.
