In order to obtain the fire parameters of cable tunnels and study the time-dependent and spacedependent distribution of the air temperatures and fire smokes inside the tunnels, cable tunnel model is established and fullscale fire simulation is made by means of FDS developed by NIST (National Institute of Standards and Technology). The distribution pattern of the smoke density, oxygen density and temperature are obtained by means of processing and analysis of the experiment data, so as to provide some effective methods for fire-fighting, rescuing and escaping. Furthermore, some suggestion is made on fire prevention.

The results indicate that the cell only doped with Al2O3 (Cell 1) is of the worst output performance at 850 ℃, the output power density being 0. 083 W/cm^2, and that the cell doped with Al2O3 and coated with buffer layer (Cell 2) is of the best output performance at the same temperature, the output power density being 0.120W/cm^2. AC impedance spectroscopy analyses indicate that the interface resistance and Ohmic resistance of Cell 2 are obviously less than those of Cell 1, meaning that insulative nickel aluminum spine1 is generated by the reaction of Al2O3 and NiO during the sintering at a high temperature.

结果表明：850℃时，含Al2O3的电池输出性能最差，输出功率约为0.083 W/平方公分；含Al2O3并具有过渡层的电池输出性能最好，输出功率约为0.120 W/平方公分；交流阻抗谱分析表明，含Al2O3并具有过渡层的电池的欧姆电阻与界面电阻均比不含过渡层的明显减小，说明YSZ中添加的Al2O3在高温烧结过程中，与阳极材料NiO发生反应生成不导电的镍铝尖晶石。
