固态储氢装置轴向传热与吸氢动力学耦合研究
Coupled study of axial heat transfer and hydrogen absorption kinetics in solid-state hydrogen storage devices
摘要
Abstract
Metal hydride hydrogen storage has emerged as a prominent research focus due to its potential for highly efficient hydrogen energy storage.The exothermic nature of hydrogen absorption reactions in metal hydrides renders thermal management a critical factor in determining system performance.This study systematically investigates the coupled characteristics of axial heat transfer and hydrogen absorption kinetics in a solid-state hydrogen storage devices,using LaNi5 as the representative material to explore the interplay between heat and mass transfer during hydrogen uptake.A simulation model of the storage device was developed,and numerical simulations were conducted based on a multiphase heat and mass transfer framework.The results reveal the spatio temporal evolution patterns of temperature fields and hydrogen uptake:in the initial reaction phase,pronounced exothermic effects lead to rapid temperature rise in the central region and yield peak hydrogen absorption rates;during the transition phase,heat conduction and cooling reduce the high-temperature zones,with a gradual decline in absorption rates;in the steady-state phase,the device system approaches thermodynamic equilibrium.The findings indicate that axial heat transfer efficiency and hydrogen diffusion resistance jointly govern storage performance,with optimal absorption rates observed at the base and significant diffusion limitations occurring at the top.The research findings clarify the interaction mechanism between heat axial heat transfer and hydrogen absorption kinetics,providing a foundation for the further development and application of thermal management strategies in solid-state hydrogen storage devices.关键词
