HUMIDIFIER FOR FUEL CELL [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying device for use in a fuel cell, and more particularly, to a humidifying device for use in a fuel cell, Thereby minimizing the pressure deviation between the flow passages and allowing the flow rate to be uniformly formed through the flow passages.

Generally, a fuel cell is a power generation type battery that produces electricity through the combination of hydrogen and oxygen. Unlike a general chemical cell, a fuel cell can continuously produce electricity as long as hydrogen and oxygen are supplied. It is a method to convert it into electrical energy, so there is a merit that the emission of pollutants during power generation is small.

Among these fuel cells, the polymer electrolyte fuel cell has advantages of miniaturization, and thus it has a high value in use now and in the future.

In a polymer electrolyte fuel cell, a predetermined amount of water is supplied to a polymer electrolyte membrane of a membrane electrode assembly (MEA) to maintain a proper water content, so that power generation efficiency can be maintained.

Bubbling, direct injection, and humidifying membrane method are the methods of humidifying the polymer electrolyte membrane. Among them, the humidifying membrane method is to increase the water content in the air by bringing the external air into contact with the hollow fiber containing moisture , And this humidifying air is supplied to the electrolyte membrane.

Such a hollow fiber membrane humidifying device basically has a structure in which the inflow case 10, the connection case 30 and the discharge case 20 are arranged in a state of being connected back and forth as shown in FIG.

A hollow fiber (not shown) is filled in the inflow case 10, the connection case 30, and the discharge case 20.

In this state, outside air is introduced into the inflow case 10 and comes into contact with the hollow fiber in the inflow case and primarily contains moisture.

And then sequentially contacts the connection case 30 and the discharge case 20 to make contact with the hollow fiber of the corresponding point in a second or third order so as to contain moisture and to be discharged to the outside through the air discharge port of the discharge case .

At this time, as shown in FIGS. 2 to 4, the first flow path 14-1 of the inflow case 10 passes through the upper end of the first accommodation space 11-1 in a state where one end thereof is connected to the air inlet To the opposite side.

The second flow path 14-2 includes a first flow path 11-1 and a second flow path 11-2 in a state where one end of the second flow path 14-2 is connected to the air inlet, ≪ / RTI >

In addition, the barrier-wall flow passage 12-1 is formed in the partition wall, and one end of the barrier-wall flow passage 12-1 is connected to the air inlet, passes between the first and second accommodation spaces 11-1 and 11-2, And is integrated with the ends of the flow paths 14-1 and 14-2.

That is, the integrated flow path 146, in which the respective flow paths are integrated, is formed at a position opposite to the side where the air inlet 13 is formed in the inflow case.

In this state, the air introduced through the air inlet is divided into the first and second flow paths 14-1 and 14-2 and the partition flow path 12-1, and then moved along the respective flow paths, 1 into the first and second accommodation spaces 11-1 and 11-2-1 via the inflow windows 14-3 and 12-2 and contact with the hollow fiber while the rest of the air enters the first and second accommodation spaces 11-1 and 11-2-2, 146), and then distributed and distributed to the respective flow paths.

However, in the prior art, the sectional area of the first and second flow paths 14-1 and 14-2 of the inlet case 10 is the same as that of the septum channel flow path 12-1, and the inlet windows 14-3 and 12- 2 have the same diameter.

In the process of supplying external air into the inflow case through the air inlet 13, the external air exits the air inlet 13 as shown in FIG. 2, and at the same time, -2), the pressure at the corresponding point is formed to be extremely high as the stagnation section is instantaneously formed around the inlet of the partition wall flow passage 12-1 (the point is denoted by dots, the density of dots The higher the pressure, the higher the pressure)

As the septum passage 12-1 narrows, the air flow rate in the septum passage 12-1 increases instantaneously as compared to the periphery of the flow passage inlet as shown in FIG. 3, and toward the opposite end, that is, toward the integrated passage 146 (The faster point is indicated by a dot, the higher the density of the point, the faster the speed)

In addition, the pressure distribution in the bulkhead flow passage is formed to a very low pressure up to a certain section at the inlet of the bulkhead flow passage 12-1, and the pressure rises toward the opposite end. And the pressure in each of the two flow paths 14-1 and 14-2 and each containing space.

That is, in the prior art, basically, the pressure in the partition wall flow path 12-1 is lower than the pressure in the first and second flow paths 14-1 and 14-2 and the first and second accommodation spaces 11-1 and 11-2 And the air flow rate is also higher.

Therefore, due to the above pressure difference, air passing through the partition wall flow path 12-1 can not flow smoothly into the respective accommodation spaces 11-1 and 11-2. Instead, the first and second accommodation spaces 11-1, A phenomenon that the air in the discharge port 11-2 flows into the partition wall flow path 12-1 occurs.

Therefore, the flow rate supplied to each containing space through the partition wall flow path 12-1 is less than the flow rate supplied through the first and second flow paths 14-1 and 14-2, and the flow rate deviation is severely formed.

In addition, the first and second flow paths 14-1 and 14-2 and the septum channel flow path 12-1 have the same cross sectional area as the first and second flow paths 14-1 and 14-2, Since the inflow window 14-3 and the inflow window 12-2 of the partition wall flow passage 12-1 are formed to have the same area, the flow rate deviation becomes larger.

Also, the first and second flow paths 14 and 12-1 themselves increase in pressure and flow rate as they move from the air inlet side to the opposite integrated flow path side.

Since the pressure fluctuation is formed in each of the partition wall flow path 12-1 and the first and second flow paths 14-1 and 14-2 as well as the interval between the partition wall flow path 12-1 and the first and second flow paths 14-1 and 14-2, The flow rate increases as the flow rate increases toward the inflow window.

In other words, the pressure difference between the septum channel 12-1 and the first and second flow channels 14-1, 14-2, and the flow rate between the respective inlet windows are not uniform due to the pressure difference of each channel itself , The contact between the hollow fiber in the inflow case and the outside air becomes uneven.

5, 6, 7, 8, and 9 formed on the barrier-wall flow path 12-1 as shown in the following Table 1 as a result of the experiment using this conventional technique It can be seen that the flow rate through which the gas flows is significantly smaller than the flow rate through the inlet windows 1, 2, 3, 10, 11, and 12 of the other flow channel 14.

In addition, it can be seen that each flow path itself has a much larger flow rate from the inflow windows 1, 4, 7, 10 toward the inflow windows 3, 6, 9, 12 toward the opposite inflow window.

Hereinafter, specific configurations and effects of the present invention will be described based on the embodiments shown in the drawings.

The humidifying device for a fuel cell according to the present invention comprises an inflow case 100, a connection case 200, a discharge case 300 and a hollow fiber 400 as shown in FIGS. 6 to 8 .

First, the inflow case 100 accommodates one end of a hollow fiber 400, which will be described later, and the first contact between the hollow fiber 400 and the outside air,

The air inlet 120 and the accommodation space are communicated with each other through a flow path in a state where the air inlet 120 of the outside air is formed at one side and the accommodation space for accommodating the hollow fiber 400 is formed at the inside. Structure.

The accommodation space is divided into a structure in which the first accommodation space 112 is located on the upper side and the second accommodation space 114 is located on the lower side with respect to the partition 130 formed in the transverse direction at the intermediate point.

That is, the first and second accommodation spaces 112 and 114 are formed in a vertically stacked form with respect to the barrier ribs 130.

In this case, the first and second accommodation spaces are formed in a rectangular shape as a whole, and curved portions 111 are formed at respective corners.

In this state, an air inlet 120 is formed in the inflow case 100. The air inlet 120 serves as an inflow passage for contacting the hollow fiber 400, And is formed in the middle of the inflow case 100, that is, on the same line as the barrier ribs 130.

An inflow channel is formed in the inflow case 100.

The inflow channel is configured to guide the outside air introduced through the air inlet 120 to be described later to move along the periphery of the first and second accommodation spaces 112 and 114 and into the accommodation spaces 112 and 114 And is further divided into a distribution passage 142 and a first passage 143, a second passage 144, a partition wall passage 145 and an integrated passage 146.

The distribution channel 142 is a point where the air that has passed through the air inlet 120 is distributed to the first and second flow paths 143 and 144 and the barrier flow channel 145 which will be described later. Is formed in a section between the outlet of the middle air inlet 120 and one side edge of the first and second accommodation spaces 112 and 114 opposed thereto.

The partition wall flow path 145 is formed in the partition wall 145 so that the air introduced through the air inlet 120 is moved along the inside of the partition wall and through the lower side of the first accommodation space 112 and the upper side of the second accommodation space 114, To the space 112 (114).

The barrier ribs 145 are formed inside the barrier ribs 130 in a state where one side is connected to the distribution channel 142 and extend through the other end of the barrier ribs 130 formed along the left and right width direction of the barrier ribs.

The partition wall window 156 is formed in the partition wall flow passage 145. The partition wall window 156 allows the air flowing along the partition wall flow passage 145 to flow into the first and second accommodation spaces 112 and 114 simultaneously And is formed at the upper and lower sides with respect to the barrier-wall flow passage 145, and is formed at regular intervals along the left-right width direction of the partition wall.

The first flow path 143 guides the air that has passed through the air inlet 120 to the upper portion of the first receiving space 112 and passes through the upper portion of the first receiving space 112, To the first accommodating space 112 through the through-hole.

The first flow path 143 extends from one side of the rim of the first accommodation space 112 toward the distribution flow path 142 to the upper and opposite side sections in a state where one side is connected to the distribution path 142. .

In this state, the end portion of the first flow path 143, which surrounds the side opposite to the distribution flow path 142, is formed to communicate with the barrier rib flow path 145.

At this time, a first inflow window 152 is formed in the first flow path 143. The first inflow window 152 allows the air flowing along the first flow path 143 to flow into the first accommodation space 112 And is arranged at regular intervals in the upper section of the first accommodation space 112 of the first flow paths 143. [

The second flow path 144 is formed so that the air having passed through the air inlet 120 is guided to the lower portion of the second accommodation space 114 and passes through the lower portion of the second accommodation space 114, To the second accommodating space (114).

The second flow path 144 extends from one end of the second accommodation space 114 toward the distribution flow path 142 to the lower end and the opposite end of the second accommodation space 114, .

In this state, the end portion of the second flow path 144, which surrounds the side opposite to the distribution flow path 142, is formed to communicate with the end portion of the barrier rib flow path 145 and the first flow path 143.

As the end portions of the respective flow paths 142, 144, and 145 opposite to the distribution flow path 142 communicate with each other, the integrated flow path 146 is formed in which the air passing through each flow path is mixed and distributed .

At this time, a second inflow window 154 is formed in the second flow path 144, and the second inflow window 154 allows the air to be moved along the second flow path 144 to flow into the second accommodation space 114 And is arranged at regular intervals in the lower side of the second accommodation space 114 of the second flow path.

The air introduced through the air inlet 120 is divided into the first flow passage 143, the second flow passage 144 and the partition wall flow passage 145 in the distribution passage 142, And the second accommodating space 114 and some of them are moved to the first and second accommodating spaces 112 and 114 through the first and second inflow windows 152 and 154 and the partition wall window 145 And the rest are mixed in the integrated flow path 146 after passing through the respective flow paths, and then mixed and dispersed again into the respective flow paths.

In this state, the communication passage 146 is further provided with a separate communication blocking portion 160 in the present invention.

The communication blocking portion 160 prevents the end portions of the first and second flow paths 143 and 144 and the barrier flow path 145 from communicating with each other in the integrated flow path 146, The first blocking portion 162 and the second blocking portion 164. The first blocking portion 162 and the second blocking portion 164 serve to prevent the air from flowing out of the communication passage 145.

The first blocking portion 162 is formed in a plate shape and protrudes from one wall surface of the integrated flow path 146 and extends between the end portion of the first flow path 143 and the second flow path 144, And is located at the boundary point to block the corresponding end-to-end communication structure of the first and second flow paths (143, 144).

And the second blocking portion 164 is also in the form of a plate and is positioned in the integrated flow path 146 vertically erected with the first blocking portion 162, And the opposite surface thereof is positioned in a structure that blocks the end portion of the barrier-wall flow passage 145. [0064]

As a result, contrary to the structure in which the end portions of the first flow path 143, the second flow path 144, and the barrier flow path 145 are mutually integrated in the integrated flow path 146, The end portions of the first and second openings can not communicate with each other and are shut off from each other.

The air that has not escaped into the accommodation space through the windows of the air passing through the first and second flow paths 143 and 144 and the partition wall flow path 145 can not escape into the integrated flow path through the end portions of the respective flow paths, It becomes trapped.

For reference, the first blocking portion 162 and the second blocking portion 164 may be separately manufactured and then connected to each other through welding or the like, or may be formed integrally at the same time.

The connection case 200 is connected to the inflow case 100 having such a configuration.

The connection case 200 receives an intermediate point of a hollow fiber 400 to be described later and at the same time communicates the inflow case 100 and the discharge case 300 described later. Like hollow tube with open ends at both ends, and a hollow space 400 through which the hollow fiber 400 is inserted is formed.

One end of the connection case 200 is connected to the rear end of the inflow case 100 so that the space is communicated with the first and second accommodation spaces 112 and 114 at the same time.

The air introduced into the first and second accommodation spaces 112 and 114 through the first and second flow paths 143 and 144 and the partition wall flow path 145 of the inflow case 100 flows into the first and second accommodation spaces 112 and 114, And passes through the accommodating space 112 (114) and then passes through the connecting cable continuously.

The discharge case 300 is connected to the connection case 200 installed as described above.

The discharge case 300 is a part discharged outside after inducing the external air passing through the connection case 200 to come in contact with the other end of the hollow fiber 400. The discharge case 300 shown in Figures 6 and 7, And is connected to the other end of the connection case 200 as shown in FIG.

The discharge case 300 has the same structure as that of the inflow case 100 as a whole, that is, basically, the third accommodating space 312 and the fourth accommodating space 314 are formed in the upper and lower stacking layers 311, Respectively.

A third flow path 301 is formed on both sides and the upper side of the third accommodating space 312 and a first discharge window 313 is formed in the third flow path 301 in the left and right width direction As shown in FIG.

A fourth flow path 302 is formed on both sides of the fourth accommodation space 314 and a lower end of the fourth accommodation space 314 and a second discharge window 315 is arranged in the fourth flow path do.

A second barrier rib channel 316 is formed in the second barrier rib 303 and a second barrier rib window 317 is formed in the second barrier rib channel 316 in a plurality of do.

In this state, the air discharge port 320 is formed at one side of the discharge case in such a manner as to communicate with the third and fourth flow paths 301 and 302 and the second air passage 316. At this time, A second mixing flow path 318 in which the third flow path 301, the fourth flow path 302 and the second bank flow path 316 are integrated is formed.

At this time, the air outlet 320 is formed at a position symmetrical to the air inlet 120 of the inlet case 100 in the discharge case 300, and is located on the same line as the second partition 303.

The air having passed through the connection case 200 passes through the first and second discharge windows 313 and 315 and the second partition wall window 317 after passing through the third and fourth accommodation spaces 312 and 314, The first and second flow paths 143 and 144 and the second flow path 144 and then discharged to the outside through the air discharge port 320 in a state of being integrated in the second mixing flow path 318. [

The hollow yarn 400 is installed in the inflow case 100, the connection case 200, and the discharge case 300 connected thereto.

The hollow fiber membrane 400 serves as a water supply source for supplying moisture to the introduced external air. The hollow fiber membrane 400 has a plurality of strands stacked in a horizontal state and each hollow fiber tube has a hollow tube shape.

The bundle-shaped hollow fiber 400 has an intermediate portion passing through the inside of the connection case 200 in a state where one end portion of the hollow fiber 400 is received in the first and second receiving spaces 112 and 114 of the inflow case 100, Are accommodated in the third and fourth accommodation spaces (312, 314) of the discharge case (300).

Since the known hollow fiber 400 is used, further explanation is omitted.

Hereinafter, the operation of this embodiment by this configuration and the unique effects generated in the process will be described.

First, when moisture is supplied into each of the hollow fibers 400, the entire hollow fiber is in a state containing water.

In this state, when outside air is supplied to the air inlet 120, the air passing through the air inlet 120 flows into the distribution channel 142 inside the inlet case 100 as shown in FIGS. 7 and 8.

The air introduced into the partition wall flow path 145 and the first and second flow paths 143 and 144 and then introduced into the partition wall flow path 145 flows through the partition wall window 156 in the process of moving along the partition wall flow path 145, (112) (114) through the first and second accommodation spaces (112, 114) of the hollow fiber, so that moisture is contained in the first and second accommodation spaces (112, 114)

Separately, the air introduced into the first flow path 143 and the second flow path 144 is moved along the upper periphery of the first accommodation space 112 and the lower periphery of the second accommodation space 114, respectively, 2 into the first and second accommodation spaces 112 and 114 through the first inflow window 152 and the second inflow window 154 in contact with the hollow fiber to contain moisture.

At this time, as described above, not only the septum passage 145 and the air inlet 120 are located on the same line, but also the air moves along the curved portion of the first and second accommodation spaces 112 and 114 during the inflow, The flow rate of the air passing through the partition wall 145 is rapidly formed and the pressure of the partition wall flow passage is made low.

The air that has not flowed into the accommodation space through the corresponding windows of the air that has been moved along the barrier flow channel 145 and the first and second flow channels 143 and 144 flows to the ends of the flow channels 143, The ends of each of the flow paths 143, 144 and 145 are separately closed by the first blocking portion 162 and the second blocking portion 164, 143) 144 (145) and is trapped in the flow channel.

Therefore, when external air is further introduced into each of the flow paths 143, 144, and 145 continuously in this state, the pressures in the respective flow paths 143, 144, and 145 are raised together.

Accordingly, when the process is continued, the pressure in each flow path becomes uniform, and as the pressure deviation between the respective flow paths is minimized, the passage of each partition wall window 156, The flow rate becomes almost uniform with the flow rate of the first and second windows.

In addition, since the pressure increases throughout the entire barrier-wall flow passage 145, the flow rate of the barrier-flow passage 145 between the barrier-wall windows 156 is uniformly formed.

Also, the flow rate of the passage between the first and second inflow windows 152 and 154 in the first and second flow paths 143 and 144 is uniformly formed by this principle.

As the pressure fluctuation between the respective flow paths is reduced, the flow rates of the first and second inflow windows and the partition wall window are formed at the same level. As a result, the first and second accommodation spaces 112 of the hollow fibers 400, The whole section accommodated in the air inlet 114 is uniformly in contact with the air to improve the function efficiency of the air.

As a result of the experiment using the structure of the present invention, pressure deviations between the partition wall flow path and the first and second flow paths were uniformly formed.

The flow rates passing through the respective partition wall windows 4, 5, 6, 7, 8 and 9 and the first and second inlet windows 1 and 2 The flow rates of the air flowing through the air inlet ports 120 and the windows 1, 4, and 7 are minimized, (6), (9) and (12) on the opposite sides of the window (10).

Percent flow through each window (%) ① ② ③ 8.1 8.4 9.0 ④ ⑤ ⑥ 7.6 8.0 8.8 ⑦ ⑧ ⑨ 7.6 7.8 8.7 ⑩ ⑪ ⑫ 8.3 8.6 9.1

The external air in contact with the hollow fiber passing through the first and second accommodation spaces 112 and 114 is in contact with the hollow fiber even after passing through the connection case 200, 4 contact with the hollow fiber even in the receiving space.

After passing through the first and second discharge windows 313 and 315 and the second partition wall window 317 and then passing through the third and fourth flow passages 301 and 302 and the second partition wall flow passage 316, And is discharged through the air outlet 320 in a mixed state in the flow path 318.

10 is a view showing a modification of the present invention

Basically, the concept of shutting off the communication structure between the respective channels by using the communication cut-off part 160 is the same as that of the above embodiment, but the difference is that the communication cut-off part 160 is integrally manufactured in the process of manufacturing the inflow case.

That is, in the process of manufacturing the inflow case as shown in the drawing, the wall surface around the integrated flow path is made relatively thick, so that the first and second flow paths are brought into contact with the first accommodation space 112 and the second accommodation space 114 side, The end portions of the first and second flow paths are closed, and at the same time, the end portions of the partition wall flow path between the first and second accommodation spaces are also closed.

Therefore, in this case, the wall surface of the inflow case becomes the communication blocking portion 160.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. If the pressure in each flow path rises to a uniform level as the air in each flow path can not escape into the integrated flow path, and thus the deviation of the flow rate of each inflow window is minimized, It should be judged as belonging to the scope of protection.
