摘要
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。
The Characteristics of the seawater Al air fuel cell and the main factors which influence the cell power output,including seawater salt concentration,conductivity,temperature,and aluminum material’s selection,are described.The experimental results show that the conductivity of seawater electrolyte in cell being discharged is better than that of stationary seawater,but it is still rather poor.A change on seawater salt concentration and temperature cause a fluctuation on electrode potential,salt concentra tion’s share of the effect is abut 10%.Operating potential of pure aluminum alloy electrode is by 200 mV higher than industrial Al alloy one.
