The invention discloses a vehicle-mounted liquid hydrogen storage system. The system comprises a liquid hydrogen container, a self-pressurization system and the like, wherein the outer layer of the liquid hydrogen container is coated with a cold storage material; the liquid hydrogen container comprises an inner container, a high-vacuum multi-layer heat insulation layer, a middle metal wall, a cold storage material filling layer and an outer container; a high-vacuum multi-layer heat insulation layer is arranged between the middle metal wall and the inner container, and the cold storage material filling layer is arranged in an interlayer between the middle metal wall and the outer container. The cold energy storage characteristic of the cold storage material is utilized to recycle the cold energy at night, so that the outer wall surface of the high-vacuum multi-layer heat insulation layer of the container can be maintained at a temperature level lower than the environment temperature for a long time when the temperature is high in daytime, and the temperature difference between the inside and the outside of the container is effectively reduced; according to the liquid hydrogen container, the influence of the day-night temperature difference on the daily evaporation rate of the liquid hydrogen container is balanced, the lossless storage time of the liquid hydrogen in the container is prolonged, and the liquid hydrogen container is simple in structure, easy to implement technically and low in cost.

    本发明公开了一种车载液氢储存系统,该系统包括外层包覆有蓄冷材料的液氢容器、自增压系统等;液氢容器包括内容器、高真空多层绝热层、中间金属壁、蓄冷材料填充层和外容器;中间金属壁与内容器之间为高真空多层绝热层,蓄冷材料填充层设置于中间金属壁和外容器之间的夹层内;本申请利用蓄冷材料的冷量储存特性对夜间冷量进行回收利用,使容器高真空多层绝热层的外壁面在白天温度较高时能够长时间维持在低于环境温度的温度水平,有效降低了容器内外温差,平衡了昼夜温差对于液氢容器日蒸发率的影响,延长了液氢在容器内的无损存储时间,且结构较为简单,在技术上易于实现,成本较低。
