摘要

通过搭建的质子交换膜电解槽（PEMWE）实验系统,系统研究电流启动、停止、阶跃加载和减载4组波动电源工况下,进水温度和进水流量对电压、温度和能效的响应特性。结果表明：电源加载过程中,电压和回水温度对电流变化表现出相似的过调响应;提高加载电流增大电压和温度过调,降低水流量和提高水温度可有效缓解电压、温度和能源效率的波动。进水温度80 ℃、水流量60 mL/min、加载电流2 A工况下,测试电解槽波动较小。建议减小电流突变值,提高进水温度和降低进水流量以维持小型百瓦级电解槽稳定运行。

Abstract

In this study, an experimental PEMWE system was developed to systematically investigate four representative dynamic operating conditions： start-up, shut-down, step-loading, and unloading. Particular attention was given to the effects of inlet water temperature and inlet water flow rate on voltage response, temperature evolution, and energy efficiency under these transient conditions. The results indicate that during the loading process, both the cell voltage and outlet water temperature exhibit pronounced overshoot behavior in response to rapid current changes. Increasing the loading current intensifies these fluctuations. In contrast, reducing the inlet water flow rate and increasing the inlet water temperature effectively mitigate voltage, temperature, and energy efficiency fluctuations. The test electrolyzer demonstrates the smallest dynamic deviations at an inlet water temperature of 80 ℃, a flow rate of 60 mL/min, and a loading current of 2 A. For stable operation of small-scale （hundred-watt-level） PEMWE under dynamic power input, it is recommended to minimize abrupt current variations, increase the inlet water temperature, and appropriately reduce the water flow rate.
