新型自增湿燃料电池组性能研究

Study on performance of novel self-humidified fuel cell

提高质子交换膜燃料电池自增湿能力的关键在于对生成水的有效管理。采用在电极反应区之外增设水传导区的新型电极结构,氢气循环利用,阴极开放式供氧。实验结果表明,氢气操作条件对电池性能存在影响,电池组的工作稳定性较好。

The key to improve the self-humidification capacity of fuel cell stack is the effective management of product water. The novel structure of MEA with water transportation region outside the reaction region was adopted. Hydrogen was used circularly, and oxygen was open-supplied. The experimental results show that the hydrogen operation has effect on the performance of the stack. The stack presents good stability.
