Abstract

The diffusion type hydrogen storage bottle comprises an inner shell, a first heating structure, an outer shell, a second heating structure, a hydrogen pipeline and a coolant pipeline. Wherein the inner shell is provided with a plurality of coolant inner flow channels for coolant to pass through; the first heating structure is mounted on the inner shell, and the second heating structure is mounted on the outer shell; the outer shell sleeves the outer side of the inner shell, and an interlayer for accommodating a hydrogen storage material is formed between the outer shell and the inner shell; a plurality of coolant outer flow channels for coolant to pass through are arranged on the outer shell; the hydrogen pipeline is communicated with the interlayer and comprises a hydrogen inlet pipe and a hydrogen outlet pipe; the coolant line includes a coolant inlet pipe and a coolant outlet pipe. Compared with the prior art, the diffusion type hydrogen storage bottle can prevent powder accumulation while improving the heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage containers, in particular to a diffusion type hydrogen storage bottle. Background technique [0002] Hydrogen energy is a clean, efficient and safe energy carrier and secondary energy. Its storage methods mainly include high-pressure gaseous hydrogen storage, low-temperature liquefied hydrogen storage and metal hydride hydrogen storage. Compared with the high-pressure gaseous hydrogen storage method and the low-temperature liquefied hydrogen storage method, the metal hydride hydrogen storage device with the hydrogen storage alloy as the medium has the advantages of high volume hydrogen storage density, low storage hydrogen pressure, high hydrogen desorption purity, good safety and long service life. Long and other advantages. [0003] Metal hydride hydrogen storage has the following characteristics: on the one hand, the hydrogen storage alloy has a significant thermal effect during the h...
