铝燃料电池堆漏电电流的研究

Study on leakage current of aluminum fuel cell stack

介绍了铝燃料电池堆漏电电流产生机理,同时建立并简化铝燃料电池堆漏电电流的计算模型。基于模型,运行Multis im10.1软件分析电池串联个数、管路电阻和电解液电阻对漏电电流分布的影响。计算分析结果表明:在满足铝燃料电池堆系统其他要求下,减小支路内径、增加支路长度是减少漏电电流的有效方法。

In this paper, the mechanism about leakage current of aluminum fuel cell stack was explained, and at the same time, the calculation model of leakage current was established and simplified. On the basis of provided calculation model, the paper mainly analyzed the influence and trait about leakage current by Multisim10.1 software as the number of series batteries, channel resistance and electrolyte resistance. The results show that: satisfied the requirements of aluminum fuel cell stack system, it is an effective method to reduce the leakage current by reducing the diameter and increasing the length of the bypass.
