The difference from example 1 is that: a water bath device is also arranged; the tank body 1 is arranged in the water bath device; the water bath device is used for radiating heat of the tank body 1 during hydrogen absorption or heating the tank body 1 during hydrogen release.
Comparative example 1
The difference from example 1 is that only pure hydrogen storage alloy is used for filling, and the rest is the same as example 1.
The amounts of hydrogen released and the rates of hydrogen released in example 1 and comparative example 1 are shown in fig. 4 and 5.
As can be seen from fig. 4 and 5, the solid-state hydrogen storage device of example 1 had higher hydrogen discharge amount and higher hydrogen discharge rate than comparative example 1.
The present utility model is not limited to the above-described embodiments, and any modifications, improvements, substitutions, and the like, which may occur to those skilled in the art, fall within the scope of the present utility model without departing from the spirit of the utility model.
