收藏资源简介：
质子交换膜（PEM）电解水制氢是一种高效、快速响应、可适应波动性可再生能源（如风能、太阳能）的绿色制氢技术。PEM电解槽内部是一个涉及电化学、电荷传递、质量传递、动量传递和热量传递的强耦合多物理场过程。实验手段难以精确测量PEM电解槽内部（如多孔电极、催化层内部）的电流密度、温度、气体浓度和流速的分布，因此给电解槽的设计带来了一定阻碍。而通过仿真模拟可以可视化这些关键参数，预测不同结构和环境参数对系统性能的影响，从而指导组件设计和运行策略的优化，降低电解槽的成本并提高电解槽的运行效率。本数据集基于电解水产热条件，针对特定结构的流道开展流场温度及压力分布仿真研究，涵盖不同电流密度下的仿真结果，并进行相应的电解槽稳定性测试。数据采集时间为 2022 年至 2025 年，采集地点为中国科学院长春应用化学研究所。经质量校验确保数据可靠性，可为微流道热管理、电解水装置流道优化设计等领域提供数据支撑与参考依据。
Proton Exchange Membrane (PEM) water electrolysis for hydrogen production is a green hydrogen production technology featuring high efficiency, fast response, and compatibility with fluctuating renewable energy sources such as wind and solar power. The interior of a PEM electrolyzer involves a strongly coupled multi-physics process covering electrochemistry, charge transfer, mass transfer, momentum transfer, and heat transfer. Experimental methods struggle to accurately measure the distributions of current density, temperature, gas concentration and flow velocity inside the PEM electrolyzer, such as within porous electrodes and catalytic layers, which poses certain obstacles to electrolyzer design. However, simulation can visualize these key parameters, predict the impact of different structural and environmental parameters on system performance, thereby guiding the optimization of component design and operating strategies, reducing the cost of electrolyzers and improving their operating efficiency. This dataset is based on the heat generation conditions during water electrolysis, and conducts simulation research on the temperature and pressure distribution of the flow field for flow channels with specific structures. It covers simulation results under different current densities and corresponding electrolyzer stability tests. The data was collected from 2022 to 2025 at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Data reliability is ensured through quality checks, and this dataset can provide data support and reference for fields such as micro-channel thermal management and flow channel optimization design of water electrolysis devices.
