串联供气电池组性能研究

Study on the performance of the stack with reactant in series

提高自增湿质子交换膜燃料电池水管理能力的关键在于电池组结构设计。采用反应气串联供给的电池组结构,且反应气经循环回路进入电池组进行再利用。实验结果表明:氢气循环对电池组内水分的均匀分布有一定的促进作用,氧气循环操作对电池组性能影响明显。

The key to improve the water control capacity of the stack is the stack structure design. The reactants were supplied in series to obtain recycle. The experimental results show that hydrogen recirculation has some benefit to uniform the water distribution, oxygen circulation has more effect on the performance of the stack.
