    摘要： Methods for making hydrogen storage tanks may include disposing a substantially solid block of hydrogen-absorbing alloy within an activation vessel. Hydrogen gas may then be introduced into the activation vessel under conditions that will cause the hydrogen-absorbing alloy to absorb hydrogen and crack or break apart. Preferably, a substantially powdered hydrogen-absorbing alloy is formed thereby. Thereafter, the substantially powdered hydrogen-absorbing alloy can be transferred from the activation vessel to a hydrogen storage tank without substantially exposing the powered hydrogen-absorbing alloy to oxygen. The hydrogen-absorbing alloy is preferably ingot-shaped when introduced into the activation vessel. Further, the substantially powdered hydrogen-absorbing alloy is preferably produced by continuously breaking the ingot-shaped hydrogen-absorbing alloy within the activation vessel due to volume expansion caused by the hydrogen-absorbing alloy having absorbed hydrogen. The hydrogen gas preferably contacts the hydrogen-absorbing alloy under relatively high-pressure and low temperature conditions.

    摘要翻译： 制备氢储罐的方法可以包括在活化容器内设置基本上固体的吸氢合金块。 然后可以在使吸收氢的合金吸收氢并破裂或分解的条件下将氢气引入活化容器中。 优选地，由此形成基本上粉末状的吸氢合金。 此后，基本上粉末状的吸氢合金可以从活化容器转移到储氢罐，而基本上不将动力吸氢合金暴露于氧气。 吸入合金在被引入到活化容器中时优选为锭状。 此外，基本上粉状的吸氢合金优选通过由于吸收了氢的吸氢合金引起的体积膨胀，连续地破坏活化容器内的锭状吸氢合金而制造。 氢气优选在相对高压和低温条件下与吸氢合金接触。
