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（H）被认为是最终的清洁能源和克服环境问题的有效燃料。然而，氢气每体积的能量非常小，因此需要开发在轻质材料中储存氢气的有效方法。我们的目标是制备全铝散装材料的H。一旦氢化物在 Al 表面附近形成，H 就不会扩散到本体中，并且 H 会停止表面区域。在形成氢化物之前促进 H 扩散到 Al 体中非常重要。为此，通过分子动力学模拟 AlH3。我们还建议使用Al的阳极涂层并改变Al中H的键合。我们在 NIMS 制备了样品，并在 Spring8（Saitoh 博士）进行了高压氢化实验。通过阳极涂层在铝块内部发生氢化，从而增加了储氢量。我们注意到阳极涂层是制备块状 AlH3 材料的一种有希望的方法。
