碱性锌氧燃料电池性能的实验研究

Research on the performance of the alkaline zinc-air fuel battery

对以KOH溶液为电解液的碱性锌氧燃料电池进行了实验研究,探究了电解液中KOH的质量分数和电解液的用量(液面高度)对电池放电特性的影响.实验发现,用40 ml质量分数为40%左右的KOH电解液最有利于延长电池的放电时间,改善电池的性能.

Taking the KOH solution as electrolyte of the alkaline zinc-air fuel battery, it was explored the impact laws of the concentration and the volume of the KOH electrolyte to the zinc-air fuel battery＇s discharge performance. It was found that taking 40 ml volume, around 40% concentration KOH solution as electrolyte of the fuel battery was most effectively to extend the discharge time and improve the battery performance.
