| 摘 要： | 用有限差分法和二维导热模型计算了圆柱形金属氢化物储氢装置内部储氢过程的温度场分布,结果表明空气换热型储氢装置内部的合金反应床存在明显的温度梯度场,吸氢时储氢装置中心部位的温度最高,需要强化其芯部换热条件,以提高储氢装置的储放氢性能.对比研究了铸态以及甩带快淬工艺制备 TiV0.41 Fe0.09Mn1.5合金吸放氢循环寿命,表明甩带快淬工艺可以显著提高储氢合金的吸放氢循环性能.以甩带快淬工艺制备的TiV0.41Fe0.09Mn1.5合金为工质的储氢装置,经过3 600次吸放氢循环后的容量保持率达到94%以上.

| Abstract: | The temperature field of the inner cylindrical canister was simulated by using finite difference method and 2D heat transfer model during the hydrogenation process. It is showed that a temperature gradient is distributed obviously in the metal hydride bed, and the ceutric place of the canister has the highest temperature. Therefore, heat assembled in the centric place must be intensively transferred to improve the hydrogen storage properties of the metal hydride canister. In order to improve the hydrogen absorption/desorption cycle performance of the canister, the cycle life of as-cast and melt-spinning TiV0.41 Fe0.09Mn1.5 alloy was comparatively studied. It is indicated that the cycle life of the melt -spinning alloy is considerably longer than that of the as-cast one. The canister prepared by using melt-spinning TiV0.41Fe0.09Mn1.5 alloy has 94% of the hydrogen storage capacity after 3600 cycles. |
