| 摘要: |
| 金属氢化物储氢系统具有体积密度大、安全性高、氢气纯度高等优势,能够满足燃料电池汽车的储氢与供氢需求,是最具发展前景的储氢方式之一。通过建立金属氢化物储氢系统吸收和释放氢气过程动态模型与热交换模型,结合实验测试,研究其在不同反应过程中的动态性能。研究表明:当环境温度在一定范围内,低温有助于氢气吸收,而高温能够提高氢气释放的动力性;增大氢气流速、降低储氢材料体积分数有助于提高氢气吸收与释放效率。 |

| Abstract: |
| Metal hydride hydrogen storage has the advantages of high hydrogen storage volume density, high safety, and high hydrogen purity, which can meet the hydrogen storage and supply needs of fuel cells in both mobile and fixed scenarios. It has become one of the most promising hydrogen storage methods. This work studies the dynamic performance of metal hydride hydrogen storage systems under absorption and desorption process by establishing dynamic models and heat exchange models. The dynamic properties of metal hydride hydrogen storage system are analyzed in different reaction process with the experimental test. Results show that when the ambient temperature is within a certain range, low temperatures are conducive to hydrogen absorption, while high temperatures can improve hydrogen release dynamics. Besides, raising the flow rate of hydrogen and reducing the volume fraction of hydrogen storage materials can help to improve the efficiency of hydrogen absorption and desorption reaction. |
