摘要

能量输入的电压波动不仅会影响质子交换膜水电解 (PEMWE) 系统的整体制氢效率和稳定性，还会对单个组件的长期使用寿命构成重大挑战。本研究以关键部件--双极板为重点，研究了铂涂层钛双极板在模拟波动电压条件下的响应行为。通过整合表面相分析和电化学测试结果，本研究阐明了双极板对不同电压波形和频率的响应特性。研究结果对电解水制氢过程中的上游能量控制具有重要意义。

Response characteristics of platinum coated titanium bipolar plates for proton exchange membrane water electrolysis under fluctuating conditions

Voltage fluctuations in energy input not only impact the overall hydrogen production efficiency and stability of Proton Exchange Membrane Water Electrolysis (PEMWE) systems but also pose significant challenges to the long-term service life of individual components. This study focuses on the key component − bipolar plates and investigates the response behavior of platinum-coated titanium bipolar plates under simulated fluctuating voltage conditions. By integrating surface phase analysis and electrochemical testing results, this research elucidates the response characteristics of the bipolar plates to different voltage waveforms and frequencies. And the findings hold substantial significance for the upstream energy control in hydrogen production through water electrolysis.

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
