钛钒铬基合金的贮氢性能研究

钛钒铬基贮氢合金贮氢量大，吸放氢条件温和，是国内外贮氢材料研究的热点之一。为此研究了钛钒铬基合金中V、Cr含量对贮氢性能的影响，结果表明：随着金属元素V含量的增加，合金的放氢平台压力略有降低和吸放氢量略有增大。而随着金属元素Cr含量的增加，合金的放氢平台压力升高，放氢量则明显提高。随着放氢温度提高放氢的平台压力升高，放氢量则增大。

A STUDY ON HYDROGEN STORAGE PROPERTIES OF TiVCr BASED ALLOYS

TiVCr based hydrogen storage alloy was one of the attractive hydrogen storage materials with high hydrogen storage capacity and moderate conditions for absorption and desorption. The influence of V and Cr content on the hydrogen storage properties of TiVCr based alloys was investigated. The desorbing plateau pressure of the alloys decreased slightly and the capacity of absorption and desorption increased slightly with increasing V content. However, the desorbing plateau pressure of the alloys increased and the desorption capacity increased apparently with increasing Cr content. The desorbing plateau pressure and the desorption capacity of the alloy increased with improving the desorbing temperature.
