Abstract: As an important secondary energy,the hydrogen has become very popular in many countries due to its avaialibility,convenient storage and transportation,clean and environmental protection,and efficient usage. High-pressure hydrogen storage vessel is the important storage and transportation equipment of hydrogen energy. The hydrogen embrittlement problem is the bottleneck of hydrogen energy and its related technology development,which has gradually developed into a very crucial and active research area in the metal material science. Thermal desorption spectroscopy(TDS)has become a widely used method to investigate the characteristics of hydrogen traps in metallic materials. First,the effect of the transformation of hydrogen traps during the heating procedure on the experimental results and its analysis of the TDS were discussed including the relatively comprehensive description of the set-up and the complete measurement principle and development history. Then the effect of hydrogen pre-charging and discharging processes on the TDS results were depicted while discussing the sample preprocessing technology and the advantages or disadvantages of TDS. Subsequently,the applicability of the three fitting models and the complexity of the deconvolution process were discussed when the TDS curves of two or more hydrogen traps overlaped with one another. Finally,the state of the art and the outlook for the post-processing theories and research development of TDS data were presented.

Key words: TDS, hydrogen storage vessel, hydrogen trap, hydrogen charging technology, fitting model

摘要: 氢能作为重要的二次能源,因其具有来源多样、储运便捷、清洁环保、利用高效等优点受到了各国的青睐。高压储氢容器是氢能的重要储输设备之一,其材料氢脆问题是氢能及其相关技术发展中的瓶颈,并逐渐发展为金属材料科学领域中一个非常重要且活跃的研究方向。热脱附谱(TDS)作为一种研究材料中氢陷阱特性的重要方法,得到了国内外学者的广泛使用。本文首先在综合介绍TDS装置及其测试原理的基础上,讨论了升温热脱过程中可能发生的氢陷阱变化对TDS结果及分析的影响。然后通过对TDS试样预处理技术发展水平及各技术利弊的分析,讨论了充氢技术和参数的选择以及充放氢过程对TDS试验结果的影响。最后,基于TDS数据后处理的现有理论及研究进展,讨论了TDS 3种拟合模型的适用性以及在其处理多陷阱曲线重合问题时反褶积过程的复杂性。
