Problems solved by technology

[0009] However, even in the case of joining or welding, in order to join and integrate members of different materials, the assembly is limited. Therefore, joining a member made of a hard material to a fuel supply container made of a flexible material usually more difficult
In particular, when the main body of the supply container is multi-layered, the range of selection of member materials integrated with this connection is significantly narrowed.
[0010] On the other hand, it is also conceivable to perform mechanical joint integration by screw fastening or concave-convex fitting, but in this case, there is a possibility that the joint part made of a flexible material may fall off due to insufficient strength.
[0011] In addition, in the case of screw fastening, the members rub against each other during screw fastening, thereby possibly generating powdery friction dross.
Furthermore, when such frictional debris is mixed into the fuel filled in the refueling container, there is a problem of deterioration of the fuel, clogging and other troubles.

[0088] First, a first embodiment of the refueling container of the present invention will be described.

[0089] here, figure 1 (a) is a partial notch front view showing the outline of this embodiment, figure 1 (b) is a schematic side view of this embodiment. in addition, figure 2 yes figure 1 (b) B-B section view.

[0090] The refueling container 1 of the present embodiment includes a container body 10 having a nozzle portion 11 , a body portion 12 , and a bottom portion 13 .

[0091] In the present embodiment, the container main body 10 is made to reduce its volume, inject fuel such as methanol filled inside in a predetermined amount into the fuel storage part of the fuel cell, and then recover the volume while inhaling the atmosphere gas in the fuel storage part, and pass These actions are cycled for continuous fuel injection operations.

[0092] Such a container main body 10 can be obtained as follows, from high-density polyethylene (HDPE), low-density polyethylen...

[0147] Next, a second embodiment of the refueling container of the present invention will be described.

[0148] in addition, Figure 16 It is a cross-sectional view of main parts showing the outline of this embodiment, and it is different from that of the above-mentioned first embodiment. figure 1 (b) B-B sectional view is equivalent. This embodiment is defined as a modified example of the first embodiment described above.

[0149]In the above-mentioned first embodiment, the coupling 20 is formed so as to be fitted with the nozzle part 11, however, it is not limited to the direct attachment device of the coupling 20 to the nozzle part 11. In this embodiment, if Figure 16 As shown, the coupling 20 is screwed to the outer peripheral surface of the nozzle part 11 while inserting the opening end edge of the nozzle part 11 between the outer peripheral cylindrical part 23 and the inner peripheral cylindrical part 241 formed in the coupling 20 .

[0150] In this case, when the...

Abstract

A convex stripe 231 is disposed on the side surface of a coupler 20 and a step portion 53 of the cylinder member 50 is brought into contact with the upper surface of the convex stripe 231, to thereby engage the cylinder member 50 with the coupler 20 and also to fit a fitting projection 312 formed on a rising portion 31 into a fitting hole 51 of the cylinder member 50, thereby allowing the cylinder member 50 to be stretched over and installed on the coupler 20 and the side surfaces of rising portion 31, making difficult to dismount the coupler 20.

Description

technical field [0001] The present invention relates to a refueling container for reducing the remaining amount of fuel from the outside in a direct methanol fuel cell, etc., in which a liquid fuel such as ethanol is directly supplied without using an improver to cause an electrochemical reaction. Inject and replenish fuel into the fuel storage part of the fuel cell. Background technique [0002] In recent years, direct methanol fuel cells (DMFC), which can produce electrochemical reactions by directly supplying methanol, the fuel, to the anode (fuel electrode) without using an improver for extracting hydrogen (cations), are suitable for small equipment In particular, fuel cells for portable devices have attracted people's attention. In addition, various proposals have been made for such a melt supply device for DMFC. [0003] For example, Patent Document 1 describes that a fuel supply container integrally molded with a flexible resin and enclosing methanol is applied, a s...
