用γ-LiAO2粉料和带铸法制备电池隔膜。隔膜有很高的阻窜能力和较低的欧姆极化。在电流密度为200和246 mA/cm2下放电时，用此膜组装的电池组（三对电池，电极面积为122 cm2）输出电压分别为2.01和1.78 V，输出功率达53.4 W.于200和300 mA/cm2下放电时，单电池（电极面积为28 cm2）输出电压分别高于0.85和0.75 V, 输出功率约6.6 W. 补偿隔膜收缩导致电池性能的提高.

The matrix prepared with γ-LiAlO2 powder and by tape cast displayed higher ability of preventing from gas cross-over and lower ohmic polarization. The voltages of the stack (three cells,122 cm2) stacked with the matrix were 2.02 and 1.78 V at 200 and 246 mA/cm2, respectively, and the output power reached 53.4 W. The cell(28 cm2) voltages were 0.85 and 0.75 V at 200 and 300 mA/cm2, respectively，and the output power was about 6.6 W. Compensating the shrinkage of matrix in stacking cells promoted the enhancement of the MCFC performance.
