0.18 g Li slice was put into 100 ml ethanol and 1 ml acetyl-acetone solution and then the precursor of nano-LiAlO2 was synthesized by electrolysis of aluminum for 6 h at the current of 0.2 A in the above.Nano-LiAlO2 was obtained at 550℃ for 2 h after drying and hydrolysis of the precursor.The products were characterized by XRD

TEM and Raman.The results indicate that the precursor should be calcined at 550℃ in order to make the nano-sized LiAlO2 of 30 nm.In molten carbonate fuel cell stack（MCFC）

the average opening circuit voltage of individual cell is about 1.15 V.The density of the electric current reaches 187 mA·cm-2 .The output power of stack is 217.8 W.The cell was operated for 10 thermal circles without reducing its performance.
