Background
In recent years, hydrogen fuel automobiles using hydrogen as an energy source are very hot, and represent the development direction of automobiles in the future. The hydrogen storage tanks on hydrogen-fueled vehicles currently available are roughly of two types: one is a metal hydrogen storage tank processed by steel, and the other is a light hydrogen storage tank formed by compounding carbon fiber winding and a plastic inner container. At the present stage, a high-pressure gaseous hydrogen storage means or a low-temperature liquid hydrogen storage means is mainly adopted to store and apply hydrogen in a hydrogen storage tank. In the use process of hydrogen, when the hydrogen in the hydrogen storage tank is in a fuller stage, the internal pressure of the hydrogen storage tank is maximum, and the gas outlet flow of the hydrogen is most stable and stable under the control of the gas valve; however, at the stage when the hydrogen storage amount of the hydrogen storage tank is less or 20-30% of the hydrogen storage amount remains, the pressure in the hydrogen storage tank is reduced along with the reduction of the hydrogen amount, at the moment, the gas output amount of the hydrogen storage tank is reduced, the gas output stability is deteriorated, and further the electricity conversion efficiency of the hydrogen fuel cell is influenced.
Such a phenomenon of the hydrogen storage tank is also common in the actual use of hydrogen, oxygen, or liquefied gas. For example, in the process of cutting a large steel plate by using hydrogen and oxygen, when the gas amount in the hydrogen storage tank and the oxygen storage tank is full, the hydrogen storage tank and the oxygen storage tank are vertically placed on the ground for deflation; after the spray gun is used for a period of time, when the gas flow in the hydrogen storage tank and the oxygen storage tank is less, the hydrogen storage tank and the oxygen storage tank must be laid on the ground for use, so that the flame of the spray gun can work normally. This phenomenon is also frequently seen in the field of liquefied gas cylinders, and when the quantity of liquefied gas in the gas cylinder is small, the gas cylinder must be placed on the ground to completely use up the liquefied gas in the gas cylinder.
Therefore, in view of the common defect of the hydrogen storage tank or the gas storage bottle, on the premise of not changing the installation and placement position of the hydrogen storage tank or the gas storage bottle, the gas can be discharged stably and uniformly when the gas quantity of the hydrogen storage tank or the gas storage bottle is less in the later period, so that the stability and the reliability of the application of the hydrogen gas are ensured; and the gas in the hydrogen storage tank or the gas storage cylinder is used up and used completely as much as possible, so that the capacity of the hydrogen storage tank or the gas storage cylinder is matched with the work capacity, which is still a technical problem that needs to be solved urgently today.
