Hydrogen (H) is considered to be the ultimate clean energy and an effective fuel to overcome the environmental problem. However, H gas has very small energy per volume and is desired to develop effective way to store H in a light material. Our goal is to prepare the H of whole Al bulk materials. Once the hydride is formed near surface of Al, H does not diffuse into the bulk and H stops the surface region. It is very important to facilitate H diffusion into the Al bulk before forming hydride. For this purpose, AlH3 is simulated by molecular dynamics. We also propose to use anodic coating of Al and change the bonding of H in Al. We prepared the samples at NIMS and experiments of hydrogenation under high pressure were performed at Spring8 (Dr. Saitoh). The hydrogenation takes place inside the Al bulk by anodic coating, and the amount of H storage is increased. We note that the anodic coating is a hopeful way to prepare bulk AlH3 materials.

氢被认为是最终的清洁能源和解决环境问题的有效燃料。然而，H气体具有非常小的单位体积能量，并且期望开发将H存储在轻质材料中的有效方法。我们的目标是制备全铝块体材料的H。一旦氢化物在Al表面附近形成，H不会扩散到本体中，并且H停止表面区域。在形成氢化物之前，促进H扩散到Al中是非常重要的。为此，AlH3是模拟分子动力学。我们还建议使用铝的阳极涂层和改变铝中的H键合。我们在NIMS制备样品，并在Spring8（斋藤博士）进行高压下的氢化实验。通过阳极包覆，氢化反应发生在铝块体内部，贮氢量增加。我们注意到，阳极涂层是一种有希望的方法来制备块体AlH3材料。
