金属氢化物作为贮氢材料,合金中的氢原子密度可与在100牛顿/mm~2下压缩的氢气的密度比拟,而不需要笨重的高压容器.通常,希望贮氢材料具有以下特性:1.贮氢量大,释放量也大;2.氢化物的生成热为29—37千焦耳/克分子左右时,在室温附近要具有适当的氢的平衡分解压(0.1—1牛顿/mm~2);3.价廉;

Metal hydride as a hydrogen storage material, the density of hydrogen atoms in the alloy can be compared with the density of hydrogen compressed at 100 Newtons / mm 2, without the need for cumbersome high pressure vessels.Generally, it is desirable that the hydrogen storage material have the following properties: 1 .Hydrogen storage capacity, the release amount is large; 2. Hydride heat of generation for the 29-37 kJ / mol around, at room temperature near the appropriate equilibrium pressure of hydrogen decomposition (0.1-1 Newton / mm ~ 2); 3. cheap;
