在进行贮氢合金设计时 ,首先要选择好适当的构成元素进而确定其成分。作为贮氢合金的构成元素至少是由氢化物生成元素 (Ａ)和非氢化物生成元素 (Ｂ)两个元素组成。Ａ原子浓度越高 ,即Ａ/Ｂ组成比越大 ,则贮氢量应该越高。因为Ａ元素越多时 ,贮氢合金的Ｂ Ｈ结合数就会增多 ,但 Hydrogen storage alloy in the design, we must first select the appropriate elements to determine its composition. The constitutional element as the hydrogen storage alloy is composed of at least two elements of a hydride forming element (A) and a non-hydride forming element (B). The higher the A atom concentration, ie, the greater the A / B composition ratio, the higher the hydrogen storage capacity should be. Because A element is more, hydrogen storage alloy B H binding number will increase, but
