摘要
通过暂态实测方法,研究了质子交换膜燃料电池(PEMFC)的动态响应及电压建立。通过使用燃料电池测试系统、高精度示波器和自行设计的开关电路,在不同的运行条件下对PEMFC的电响应进行测量,实验结果证明PEMFC的动态响应和电压建立与其运行条件以及单体电池在电堆中的位置有非常紧密的联系。
The electrical behavior of proton exchange membrane fuel cell （PEMFC） was experimentally investigated by measurements of transient response. By using a fuel cell test system, a high precise oscilloscope and in-house running switch control circuit, the electrical dynamic response of a PEMFC was conducted under different operating conditions. The experimental results showed that the dynamic response and voltage build-up of a PEMFC were significantly dependent on the operating conditions and individual cell location in a fuel cell stack.
