Description
Technical Field
The present invention relates to an air supply apparatus for a fuel cell, and more particularly, to an air supply apparatus for a fuel cell, in which high-temperature and humid air discharged after a reaction of the fuel cell is recycled to improve the performance of the fuel cell.
Background
Generally, a fuel cell system mainly includes a fuel cell stack configured to generate electric power, a fuel supply device configured to supply fuel (hydrogen) to the fuel cell stack, an air supply device configured to supply oxygen in air, which is an oxidant required for an electrochemical reaction, to the fuel cell stack, and a cooling system configured to discharge reaction heat of the fuel cell stack to the outside of the system and control an operating temperature of the fuel cell stack.
In the fuel cell system, electricity is generated by an electrochemical reaction occurring between hydrogen as a fuel and oxygen in the air, and heat and water are discharged from the fuel cell system as reaction byproducts. A polymer electrolyte membrane fuel cell or a Proton Exchange Membrane Fuel Cell (PEMFC) includes: a Membrane Electrode Assembly (MEA) in which catalyst electrode layers are attached to both sides of an electrolyte membrane through which hydrogen ions move and in which electrochemical reactions occur; a Gas Diffusion Layer (GDL) configured to uniformly distribute reaction gas and perform a function of transmitting generated electric energy; a gasket and coupling unit configured to maintain airtightness of reaction gas and cooling water and a proper coupling pressure; and a bipolar plate electrically connected to the cell and configured to move the reaction gas and the cooling water.
In a fuel cell, when hydrogen gas as a fuel and oxygen gas (air) as an oxidant are supplied to an anode and a cathode of an MEA through channels of bipolar plates, the hydrogen gas is supplied to the anode (referred to as a "fuel electrode" or an "oxidation electrode") and the oxygen gas (air) is supplied to the cathode (referred to as an "air electrode", "oxygen electrode" or a "reduction electrode").
Meanwhile, a conventional fuel cell system includes a stack in which bipolar plates are coupled to end plates for an oxygen reduction reaction and stack cooling, and a cooling fan configured to supply air to the stack, and the air is introduced from the outside and supplied to the bipolar plates of the stack through the cooling fan.
Conventionally, air moved by a cooling fan is introduced to one end portion of the bipolar plate and discharged to the other end portion of the bipolar plate. In this case, when air passes through the bipolar plate, condensed water is generated by a fuel cell reaction.
However, in the case where low temperature and dry air are supplied from the outside, there are problems in that the performance of the fuel cell disposed in the inlet portion of the bipolar plate is reduced, and the durability of the fuel cell is reduced due to uneven fuel cell reaction. Therefore, there is a need to solve these problems.
The related art of the present invention is disclosed in korean patent laid-open publication No. 2015-0080171 (registered, 2015, 7, 9, entitled AIR BREATHING FUEL cell system and METHOD (AIR BREATHING TYPE FUEL CELL SYSTEM AND METHOD)).

The thickness of the lines or the size of the components shown in the drawings may be exaggerated and shown for convenience and clarity in the specification. Further, some terms described below are defined in consideration of their functions in the present invention, and the meanings may be changed according to the intention or custom of a user or an operator. Therefore, the meaning of the terms should be construed based on the contents throughout the present specification.
Fig. 1 is a schematic view illustrating an air supply device for a fuel cell according to an embodiment of the present invention. Referring to fig. 1, an air supply device 1 for a fuel cell according to an embodiment of the present invention includes a separator unit 10, a forward supply unit 20, and a reverse supply unit 30.
The separator unit 10 distributes air through a channel 12 comprising a plurality of plates 11. The partition unit 10 may include a perforated plate in which a plurality of holes are formed. The shape and number of holes of the perforated plate may vary according to its design.
As an example, the first to seventh plates 111 to 117 may be vertically disposed to be spaced apart from each other, and thus, the first to sixth passages 121 to 126 may be formed to distribute air. Meanwhile, in the first to sixth passages 121 to 126, an electrochemical reaction may occur due to an electrochemical reaction component including an electrolyte, and a reaction gas and cooling water may be guided.
The forward supply unit 20 supplies external air to the diaphragm unit 10. As one example, the forward supply unit 20 may be disposed on a left end portion of the partition unit 10, and the fan may be operated to supply air to the partition unit 10. Accordingly, air may pass through the diaphragm unit 10 and may be discharged to the right side of the diaphragm unit 10.
The reverse supply unit 30 resupplies the air passing through the partition unit 10 to the partition unit 10. As an example, the reverse supply unit 30 may resupply the air discharged to the right side of the barrier unit 10 from the forward supply unit 20 to the barrier unit 10 and discharge the air to the left side of the barrier unit 10.
Accordingly, low-temperature and dry external air may pass through the separator unit 10 due to the forward supply unit 20, and high-temperature and high-humidity unreacted air discharged to the right side of the separator unit 10 may pass through the separator unit 10 due to the reverse supply unit 30, so that the performance of the fuel cell may be improved.
Fig. 2 is a schematic view showing a first embodiment of the present invention. Referring to fig. 2, the forward supply unit 20 according to the first embodiment of the present invention includes a first forward fan unit 211, and the reverse supply unit 30 includes a first reverse fan unit 311.
The first forward fan unit 211 is disposed at a central portion of one end of the partition unit 10 and blows air toward the central portion of the partition unit 10. As an example, the first forward fan unit 211 may be supported by left ends of the third plate 113 and the fifth plate 115, and may blow air toward the third channel 123 and the fourth channel 124 when power is applied thereto.
The first counter fan unit 311 is disposed on at least one of the upper and lower portions of one end of the partition unit 10 and draws air from the other end of the partition unit 10. As one example, the first counter fan unit 311 may be supported by the left end portion of the first plate 111 and the left end portion of the third plate 113, and may draw air in the first passage 121 and the second passage 122 when power is applied thereto. Further, the first counter fan unit 311 may be supported by the left end portions of the fifth plate 115 and the seventh plate 117, and may draw air in the fifth passage 125 and the sixth passage 126.
The reverse supplying unit 30 according to the first embodiment of the present invention may further include a first reverse cover unit 312. The first reverse cover unit 312 covers the other end portion of the partition unit 10 to prevent air passing through the partition unit 10 due to the first forward fan unit 211 from leaking. As an example, the first reverse cover unit 312 may extend from the right end of the first plate 111 and the right end of the seventh plate 117 to cover the first to sixth passages 121 to 126. Accordingly, the air supplied by the first forward fan unit 211 may be held in the space between the diaphragm unit 10 and the first reverse cover unit 312 through the third and fourth passages 123 and 124, and pass through the first, second, fifth, and sixth passages 121, 122, 125, and 126 due to the suction force of the first reverse fan unit 311.
The reverse supplying unit 30 according to the first embodiment of the present invention may further include a first reverse guide 313. The first reverse guide 313 is disposed in a central portion of the other end of the barrier unit 10 and guides air passing through the barrier unit 10 due to the first forward fan unit 211 to flow in a vertical direction. As an example, the first reverse guide 313 may extend in a longitudinal direction of the fourth plate 114 from a right end of the fourth plate 114, be vertically disposed at an end thereof, and guide the air passing through the third and fourth channels 123 and 124 to flow in a vertical direction.
The flow of air in the air supply device for a fuel cell according to the first embodiment of the present invention having the above-described structure will be described below.
When the first forward fan unit 211 is driven and the low temperature and dry air passes through the third and fourth passages 123 and 124, a reaction occurs. Further, the high temperature and high humidity air, which does not react even when it passes through the third passage 123 and the fourth passage 124, passes through the first passage 121, the second passage 120, the fifth passage 125, and the sixth passage 126 due to the first counter fan unit 311 and causes the reaction of the fuel cell. In this case, the air passing through the partition unit 10 due to the first forward fan unit 211 may not be discharged to the outside through the first reverse cover unit 312 and the first reverse guide 313, and may be introduced into the partition unit 10 again.
Fig. 3 is a schematic diagram showing a second embodiment of the present invention. Referring to fig. 3, the forward supply unit 20 according to the second embodiment of the present invention includes a second forward fan unit 221, and the reverse supply unit 30 includes a second reverse fan unit 321.
The second forward fan unit 221 is disposed at a central portion of one end of the partition unit 10, and blows air toward the central portion of the partition unit 10. As an example, the second forward fan unit 221 may be supported by left end portions of the third plate 113 and the fifth plate 115, and may blow air toward the third channel 123 and the fourth channel 124 when power is applied thereto.
The second counter fan unit 321 is disposed in the other end portion of the partition unit 10 and blows air to the entire area of the partition unit 10. As an example, the second counter fan unit 321 may be supported by the right end of the first plate 111 and the right end of the seventh plate 117 and blow the external air toward the first to sixth passages 121 to 126.
The reverse supplying unit 30 according to the second embodiment of the present invention may further include a second reverse guide 322. The second reverse guide portion 322 may be disposed at a central portion of the other end of the barrier unit 10, and may guide the air passing through the barrier unit 10 due to the second forward fan unit 221 to flow in a vertical direction. Further, the second reverse guide portion 322 may restrict the air blown by the second reverse fan unit 321 from being introduced into the center portion of the other end of the partition plate unit 10. As an example, the second reverse guide 322 may extend in the longitudinal direction of the fourth plate 114 from the right end of the fourth plate 114 and guide the air passing through the third and fourth passages 123 and 124 in the vertical direction. The second reverse guide 322 may prevent an operation error of the second forward fan unit 221 due to a pressure difference between the second forward fan unit 221 and the second reverse fan unit 321.
The flow of air in the air supply device for a fuel cell according to the second embodiment of the present invention having the above-described structure will be described below.
When the second forward fan unit 221 is driven and the low temperature and dry air passes through the third passage 123 and the fourth passage 124, a reaction occurs. In addition, the high temperature and high humidity air, which does not react even when it passes through the third and fourth passages 123 and 124, passes through the first, second, fifth, and sixth passages 121, 122, 125, and 126 due to the second counter fan unit 321 and causes the reaction of the fuel cell. In this case, the air passing through the partition unit 10 due to the second forward fan unit 221 may be distributed in the vertical direction by the second reverse guide portion 322 and introduced into the partition unit 10 again.
Fig. 4 is a schematic view showing a third embodiment of the present invention. Referring to fig. 4, the forward direction supply unit 20 according to the third embodiment of the present invention includes a third forward direction fan unit 231, and the reverse direction supply unit 30 includes a third reverse direction guide portion 331 and a third reverse direction fan unit 332.
The third forward fan unit 231 is disposed at a central portion of one end of the partition unit 10, and blows air toward the central portion of the partition unit 10. As an example, the third forward fan unit 231 may be supported by left ends of the third plate 113 and the fifth plate 115, and may blow air toward the third channel 123 and the fourth channel 124 when power is applied thereto.
The third reverse guide part 331 is disposed in a central portion of the other end of the barrier unit 10 and guides air passing through the barrier unit 10 due to the third forward fan unit 231 in a vertical direction. As an example, the third reverse guide 331 may extend in a longitudinal direction of the fourth plate 114 from a right end of the fourth plate 114, may be vertically disposed at an end thereof, and guides the air passing through the third and fourth passages 123 and 124 to flow in a vertical direction.
The third reverse fan unit 332 is installed in the third reverse guide portion 331 and blows air toward one or more of the upper and lower portions of the partition unit 10. As one example, the third reverse fan unit 332 is supported by the upper end of the third reverse guide 331 and the first plate 111, and may supply external air to the first and second passages 121 and 122 when power is applied thereto. Further, the third reverse fan unit 332 may be supported by the lower end of the third reverse guide portion 331 and the seventh plate 171, and may supply the external air to the fifth passage 125 and the sixth passage 126 when power is applied thereto.
The flow of air in the air supply device for a fuel cell according to the third embodiment of the present invention having the above-described structure will be described below.
When the third forward fan unit 231 is driven and the low temperature and dry air passes through the third passage 123 and the fourth passage 124, a reaction occurs. In addition, when the external air passes through the first, second, fifth and sixth passages 121, 122, 125 and 126 due to the third counter fan unit 332, a reaction of the fuel cell is induced. In this case, high temperature and high humidity air that does not react even when it passes through the third and fourth passages 123 and 124 may be distributed in a vertical direction by the third reverse guide 331 and be introduced into the partition unit 10 again.
In the air supply device 1 for a fuel cell according to one embodiment of the present invention, since air that does not react even when it passes through the separator unit 10 and has a high temperature and a high humidity is introduced again into the separator unit 10, the reactivity of the fuel cell can be improved.
