叙述了海水－铝空气燃料电池的特性及影响电池功率输出的主要因素，如海水的电导、盐度、温度、铝材料的选择等。试验结果表明，电池工作时正负极之间的液相电阻比海水本身的电阻小得多，但是其液相电阻仍然偏大。海水盐度和温度的变化引起电极电势波动，盐度影响占１０％左右。高纯铝合金电极工作电势比工业铝合金电极的工作电势高２００ｍＶ以上。
Describes the seawater - aluminum air fuel cell characteristics and affect the battery power output of the main factors, such as sea water conductivity, salinity, temperature, the choice of aluminum materials. The experimental results show that the resistance of the liquid phase between positive and negative electrodes is much smaller than that of seawater when the battery is working, but the liquid resistance is still too large. Changes in seawater salinity and temperature caused the electrode potential fluctuation, salinity impact of about 10%. The working potential of high purity aluminum alloy electrode is higher than that of industrial aluminum alloy electrode by more than 200mV.
