Description
The present invention relates to a fuel tank which improves the adsorption efficiency of fuel by securing stability by lowering the pressure when storing compressed natural gas or hydrogen gas.
Generally, a high-pressure vessel such as a fuel tank of a natural gas vehicle or a hydrogen tank of a fuel cell vehicle compresses and stores natural gas or hydrogen gas fuel at a high pressure. This high-pressure vessel decompresses the compressed fuel contained therein to provide the fuel necessary for the engine.
Recently, as natural gas and hydrogen gas are attracting attention as future energy resources, development of vehicles driven by using natural gas or hydrogen gas is progressing. However, in order to store sufficient natural gas or hydrogen gas, the fuel must be compressed and stored at a high level of pressure. Accordingly, the durability of the high-pressure vessel must be sufficiently ensured so that the material and rigidity of the high- Was produced.
In order to solve this problem, a high-pressure vessel for storing natural gas or hydrogen gas using adsorbing material has been developed. In order to reduce the storage pressure when storing natural gas or hydrogen gas, It is not limited to a large extent, and even when the explosion is caused by an accident, the risk is greatly lowered as the storage pressure is low.
However, in the case of the high-pressure vessel to which the adsorbent material is applied, there are many problems in application of the actual vehicle because of the structure for stably supporting the adsorbent material and the technique for improving the adsorption efficiency.
Therefore, there is a need for a support structure for a high-pressure vessel to which the adsorbent material is applied and a technique for improving the adsorption efficiency.

The inner case may further include a filter unit for primarily filtering the foreign substances in the fuel diffused through the diffusion part, and a strainer part for filtering the foreign substances in the fuel passed through the filter unit to smoothly flow the fuel .
The diffusion portion, the filter portion, and the strainer portion are sequentially stacked and bonded from one side to the other side so that a filter portion is interposed between the diffusion portion and the strainer portion.
The diffusion portion is formed in a shape corresponding to one side of the outer case and has a plurality of diffusion holes spaced equiangularly radially from a circular center.
And the diffusion hole of the diffusion portion is formed so as to gradually increase in size in the radial direction from the center of the circular portion.
The strainer portion is formed in a shape corresponding to the diffusion portion, inserted into the other side of the diffusion portion, and coupled to the diffusion hole.
The inner case has a radial width smaller than a radial width of the outer case. The inner case and the outer case are spaced apart from each other by a predetermined distance. A plurality of elastic supporting protrusions protrude from the outer side of the inner case, Is contacted.
The elastic support protrusion is a plate spring fixed to the outer surface of the inner case and bent toward the outer case, and is elastically contacted with the inner surface of the outer case.
A plurality of through holes are formed on the outer side surface of the inner case so as to penetrate the inner and outer sides of the inner case, and a filter for filtering foreign substances is provided in the through holes.
And the inner case is formed with a dividing partition inwardly.
According to the fuel tank having the above-described structure, the storage pressure can be lowered by adsorbing and storing compressed natural gas or hydrogen gas.
In addition, as the support structure of the inner case and the outer case provided with the adsorption section is stabilized, the durability performance is ensured and the fuel supplied to the adsorption section of the inner case is uniformly diffused and the adsorption efficiency is improved.
