Description

Hydrogen generator {HYDROGEN GENERATING DEVICE}

The present invention relates to a hydrogen generator, and more particularly, to a hydrogen generator for generating hydrogen by electrolyzing water.

A hydrogen generating device using electrolysis is a device in which electric energy is applied to water containing an electrolyte or the like, and oxygen gas is generated on the anode side and hydrogen gas is generated on the cathode side as water molecules are decomposed.

Various types of devices have been developed and used as such a hydrogen generating device. In general, a pair of cases has an inlet and an outlet through which water is introduced and discharged, a positive electrode plate and a negative electrode plate are disposed in the case, and an ion film is disposed between the positive electrode plate and the negative electrode plate. In addition, as water passes through spaces formed on both sides of the case based on the ion film, the positive electrode plate, and the negative electrode plate, water molecules may be decomposed by electric energy to generate hydrogen and oxygen.

The conventional hydrogen generator as described above uses a case made of an insulator such as synthetic resin, and arranges an ion film, a positive plate, and a negative plate in close contact with the inside of the case made of the insulator.

At this time, in general, various studies have been conducted to extend the contact time between water and the ion film, the positive electrode plate, and the negative electrode plate in a hydrogen generating device. Conventionally, in general, a method of slowing the flow of water by forming a water channel inside the case so that water can proceed along a specific path, and complicating the path of water introduced into the case, has been used.

In the conventional hydrogen generator as described above, even if the water flow rate is delayed by forming a path through which water flows in the case, the efficiency of generating hydrogen by decomposing water is improved because only the time when water is in contact with the positive and negative plates is controlled There is a problem with limitations.

4 is a front view showing an anode plate of a hydrogen generating device according to an embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along the cut line AA′ of FIG. 4.

With reference to FIGS. 4 and 5, the anode receiving portion 116 formed on the anode plate 110 will be described in more detail. At this time, the cathode accommodating portion 126 formed on the cathode plate 120 is formed substantially the same as the anode accommodating portion 116, and a detailed description thereof will be omitted.

As described above, the anode receiving portion 116 includes a first anode path portion 116a, a second anode path portion 116b, and a third anode path portion 116c. Each of the first anode path portion 116a, the second anode path portion 116b, and the third anode path portion 116c may be formed in the shape of a groove formed on the inner surface of the anode body 111.

In addition, a plurality of third anode path portions 116c may be provided in the horizontal direction between the first anode path portion 116a and the second anode path portion 116b. The third anode path portions 116c are formed to be spaced apart from each other at a predetermined interval, and the plurality of third anode path portions 116c are disposed on the same plane as the inner surface of the anode body 111.

Accordingly, when the diaphragm 140 is in contact with the anode body 111, the grooves of the first anode path part 116a, the second anode path part 116b, and the third anode path part 116c are completely covered. So that the water flowing into the anode receiving part 116 through the inlet 112a moves only through the first anode path part 116a, the second anode path part 116b, and the third anode path part 116c. Can be.

In addition, the depth d1 of the first anode path portion 116a and the second anode path portion 116b may be deeper than the depth d2 of the third anode path portion 116c, and in this embodiment, the third The depth d2 of the anode path portion 116c may be about 40% (with an error range of 10%) of the depth d1 of the first anode path portion 116a and the second anode path portion 116b.

As the first anode path part 116a, the second anode path part 116b, and the third anode path part 116c are formed in the anode receiving part 116 as described above, Water may first flow through the first anode path part 116a connected to the inlet 112a and then flow to the second anode path part 116b connected to the outlet 114a through a plurality of third anode path parts 116c. have. In addition, the water moved through the second anode path part 116b connected to the discharge port 114a is discharged to the outside through the discharge port 114a. By controlling the flow path of the water introduced into the anode receiving part 116 in this way, the contact time between the water and the anode plate 110 may be increased by controlling the flow of water.

In addition, since water quickly flows through the anode plate 110, the anode receiving portion 116 formed on the anode plate 110 is compared with a case where water is accommodated in a conventional case provided separately from the anode plate or the cathode plate. Water can flow into the furnace quickly. Accordingly, when power is applied before the diaphragm 140 comes into contact with water, the diaphragm 140 may be damaged. In this embodiment, water is directly transferred to the anode receiving portion 116 formed on the anode plate 110. As it is accommodated, the diaphragm 140 can quickly contact water, so that the time for the diaphragm 140 to contact water can be reduced, and thus the diaphragm 140 can be prevented from being damaged.
