Description

Split fuel cell device Technical Field

[0001] This invention relates to a fuel cell device, and more particularly to a shunt fuel cell device. Background Technology

[0002] A fuel cell is a device that converts chemical energy into electrical energy. More specifically, a fuel cell generates electricity, gas, and water through the reaction between hydrogen and oxygen. Compared to other energy devices, fuel cells have the advantage of low pollution, making them highly promising for the automotive industry. Technical issues

[0003] However, past fuel cells:

[0004] First, its current carrying capacity is limited. If the current carrying capacity of the fuel cell is to be increased, the volume of the fuel cell will inevitably need to be increased, thereby increasing the material cost.

[0005] Second, on the other hand, the bipolar plates and graphite in traditional fuel cells are not good conductors of heat, and the bipolar plates are designed in a stacked manner. This leads to heat dissipation problems. Even if the bipolar plates can be cooled by water in the fuel cell, this only cools the outside of the bipolar plates and cannot effectively cool the inside of the bipolar plates, so the heat dissipation effect is still limited.

[0006] Third, during fuel cell operation, the reactant gases pass through the fuel cell's gas flow channels to undergo gas-ion exchange reactions. Since the metal walls cannot exchange gases, and the width of the metal walls is almost equal to the width of the gas flow channels, it is clear from the foregoing that the actual volume in the fuel cell where the reaction can take place is only about half the fuel cell's volume.

[0007] Fourth, because the fuel cell uses a single-channel gas flow design, the water produced by the fuel cell during the reaction must flow to the downstream end of the fuel cell along with the gas. This also reduces the reaction efficiency of gas-ion exchange. Technical solutions

[0008] The main objective of this invention is to provide a shunt fuel cell device to improve the current carrying capacity and reaction efficiency of the fuel cell device.

[0088] To facilitate the description of the central ideas expressed in the above technical content, specific embodiments are now described. The various elements of the embodiments are depicted according to a scale, size, deformation, or displacement suitable for illustration, and are not drawn to scale with actual elements.

[0089] Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings. It is not intended to limit the technical principles of the present invention to the specific disclosed embodiments, but the scope of the present invention is limited only by the claims and covers alternatives, modifications and equivalents.

[0090] Please refer to Figures 1 to 7. In this embodiment of the invention, the present invention provides a shunt fuel cell device 100.

[0091] Please refer to Figure 1 for details. The shunt fuel cell device 100 includes a porous substrate 10, a coil 20, and a plurality of conductive components 30.

[0092] Please refer to Figure 2. For the purpose of explaining the porous substrate 10 and the coil 20, the conductive element 30 is omitted, and a partial cross-section of the porous substrate 10 is shown.

[0093] The porous substrate 10 has a plurality of fine pores to diffuse gas to its surface. The porous substrate 10 is conductive and can serve as the anode of a shunt fuel cell device 100. The porous substrate 10 is tubular. A reaction layer 11 is present on the surface of the porous substrate 10. In one embodiment of the invention, an anti-corrosion layer can be formed on the surface of the porous substrate 10, and then the reaction layer 11 can be disposed on the anti-corrosion layer.

[0094] The porous substrate 10 has a connecting portion 12 and a diffusion portion 13. In one embodiment of the present invention, the connecting portion 12 does not have multiple fine pores, that is, the connecting portion 12 does not have an air-permeable function.

[0095] The connecting portion 12 is located at the two relatively distant ends of the porous substrate 10. The connecting portion 12 has a small diameter section 121 and a large diameter section 122. The small diameter section 121 is located at the two relatively distant ends of the porous substrate 10 and is fixedly provided with a fastener 1, such as a nut. The large diameter section 122 is adjacent to the small diameter section 121.

[0096] A diffuser 13 is located between each of the connecting portions 12. A reaction layer 11 of the porous substrate 10 is located on the surface of the diffuser 13. A winding segment 21 of the coil 20 is wound around the reaction layer 11.

[0097] Referring to Figure 3, the reaction layer 11 of the porous substrate 10 has a first catalyst layer 111, an ion exchange layer 112, and a second catalyst layer 113. The first catalyst layer 111 is located on the surface of the diffusion portion 13. The ion exchange layer 112 is located on the side of the first catalyst layer 111 away from the diffusion portion 13. The second catalyst layer 113 is located on the side of the ion exchange layer 112 away from the first catalyst layer 111.

[0098] When gas is delivered into the porous substrate 10, it diffuses from the diffuser 13 of the porous substrate 10 to the first catalyst layer 111. Hydrogen reacts with the first catalyst layer 111, releasing electrons. These electrons then flow sequentially to the ion exchange layer 112 and the second catalyst layer 113, where they combine with oxygen to undergo an electrochemical reaction, thereby generating water.

[0099] The coil 20 is located outside the porous substrate 10. The coil 20 receives electrons from the second catalyst layer 113. The coil 20 has a winding section 21 and a shunt section 22. The winding section 21 is connected to the shunt section 22, and the winding section 21 is wound around the porous substrate 10. The shunt section 22 is exposed outside the porous substrate 10 to facilitate the winding of multiple conductive elements 30.

[0100] In one embodiment of the present invention, the coil 20 has multiple shunt sections 22. These multiple shunt sections 22 are spaced apart along an axis C of the porous substrate 10 to shunt more current. This further enhances the current-carrying capacity. Furthermore, a coil 20 with a smaller wire diameter can be used while maintaining the same current carrying capacity.

[0101] Furthermore, each of the multiple shunt sections 22 has two windings 221. The two windings 221 are exposed in the porous substrate 10 and are wound around a mounting area 31 of the multiple conductive elements 30. The two windings 221 are tightly wound around the mounting area 31 in a two-wire crossing manner to make the shunt section 22 more stably wound around the multiple conductive elements 30.

[0102] Multiple conductive elements 30 are adjacent to the porous substrate 10. The multiple conductive elements 30 receive electrons from the coil 20. The multiple conductive elements 30 are connected in series sequentially. A mounting area 31 is formed between the conductive elements 30. A shunt section 22 of the coil 20 is disposed in the mounting area 31.

[0103] Referring to Figure 4, the shunt fuel cell device 100 also includes a housing 40. The housing 40 has a first exhaust port H1, a first intake port H2, a second exhaust port H3, and a second intake port H4 for inputting and outputting gas. The housing 40 is also equipped with a first electrode portion E1 and a second electrode portion E2 to provide output electrical energy. A stabilizing member 2 may also be provided at the bottom of the housing 40 to ensure that the housing 40 can be stably placed on a flat surface.

[0104] Please refer to Figure 5 for details. The housing 40 has a chamber S. The porous substrate 10, the coil 20, and a plurality of conductive elements 30 are located in the chamber S.

[0105] Please refer to Figure 6 for further details. The shunt fuel cell device 100 also includes a first electrode plate 50 and a second electrode plate 60. The first electrode plate 50 and the second electrode plate 60 are located in the chamber S.

[0106] The first electrode plate 50 is connected to the porous substrate 10. The second electrode plate 60 is connected to a plurality of conductive elements 30. The first electrode plate 50 and the second electrode plate 60 can be disposed on the porous substrate 10 and the plurality of conductive elements 30 using a fixing member 1.

[0107] When the gas reacts with the ions, the polarity of the first electrode plate 50 will be different from that of the second electrode plate 60. Wherein, the first electrode plate 50 is the anode, and the second electrode plate 60 is the cathode.

[0108] Please refer to Figure 6 for further information. The shunt fuel cell device 100 also includes a third electrode plate 70 and a fourth electrode plate 80 to increase the current carrying capacity.

[0109] The third electrode plate 70 and the fourth electrode plate 80 are located in the chamber S. The second electrode plate 60 and the third electrode plate 70 are located between the first electrode plate 50 and the fourth electrode plate 80. The third electrode plate 70 is connected to multiple conductive elements 30. The fourth electrode plate 80 is connected to the porous substrate 10. The third electrode plate 70 can be mounted on the multiple conductive elements 30 using a locking member 3, and the fourth electrode plate 80 can be mounted on the porous substrate 10 using a fixing member 1.

[0110] When the gas reacts with the ions, the polarity of the third electrode plate 70 will be the same as that of the second electrode plate 60, and the polarity of the fourth electrode plate 80 will be the same as that of the first electrode plate 50.

[0111] Referring to Figure 6, the first electrode plate 50 is located on the top side of chamber S. The third electrode plate 70 is adjacent to the first electrode plate 50, meaning the third electrode plate 70 is approximately located on the top side of chamber S. The fourth electrode plate 80 is located on the bottom side of chamber S. The second electrode plate 60 is adjacent to the fourth electrode plate 80, meaning the second electrode plate 60 is approximately located on the bottom side of chamber S. A first exhaust zone R1 is formed on the top side of the first electrode plate 50, and the first exhaust zone R1 is connected to the first exhaust port H1. A first intake zone R2 is formed between the first electrode plate 50 and the third electrode plate 70, and the first intake zone R2 is connected to the first intake port H2. A second intake zone R3 is formed on the bottom side of the fourth electrode plate 80, and the second intake zone R3 is connected to the second intake port H4. A second exhaust zone R4 is formed between the second electrode plate 60 and the fourth electrode plate 80, and the second exhaust zone R4 is connected to the second intake port H4. A reaction zone R5 is formed between the second electrode plate 60 and the third electrode plate 70.

[0112] Referring to Figures 6 and 7, both the second electrode plate 60 and the third electrode plate 70 have an opening H5. The opening H5 connects the first intake zone R2, the second exhaust zone R4, and the reaction zone R5. Both ends of the porous substrate 10 pass through the opening H5 and connect to the first electrode plate 50 and the fourth electrode plate 80, respectively. More specifically, one connecting portion 12 of the porous substrate 10 passes through the opening H5 of the second electrode plate 60 and connects to the fourth electrode plate 80, while the other connecting portion 12 of the porous substrate 10 passes through the opening H5 of the third electrode plate 70 and connects to the first electrode plate 50. Thus, when gas is introduced into the chamber S, the present invention utilizes the connected first intake zone R2, second exhaust zone R4, and reaction zone R5 to further remove heat energy from the chamber S of the housing 40. Furthermore, this feature also allows water generated by the shunt fuel cell device 100 to be discharged through the second exhaust zone R4, preventing water from affecting the gas and ion exchange reactions.

[0113] The opening H5 can be adapted to the shape of the porous substrate 10. The opening H5 is spaced apart from the porous substrate 10 by a distance D along an axis C perpendicular to the porous substrate 10. The distance D can be between 2.5 mm and 3.5 mm, for example: 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4 and 3.5 mm, etc.

[0114] Referring to Figure 6, the shunt fuel cell device 100 further includes a first charging pile group E3 and a second charging pile group E4, both capable of handling high current. The first charging pile group E3 is connected between the first electrode plate 50 and the fourth electrode plate 80; furthermore, the first charging pile group E3 passes through the second electrode plate 60 and the third electrode plate 70, thus connecting the first electrode plate 50 and the fourth electrode plate 80. The second charging pile group E4 is connected between the second electrode plate 60 and the third electrode plate 70; furthermore, the second charging pile group E4 can pass through the first electrode plate 50 and the fourth electrode plate 80. The first charging pile group E3 and the second charging pile group E4 can be connected to the first electrode section E1 and the second electrode section E2.

[0115] In one embodiment of the present invention, the shunt fuel cell device 100 further includes a plurality of first insulating members 4a and a plurality of second insulating members 4b to isolate objects of different polarities. One first insulating member 4a is located between the first electrode plate 50 and the second charging pile group E4, and another first insulating member 4a is located between the fourth electrode plate 80 and the second charging pile group E4. One second insulating member 4b is located between the second electrode plate 60 and the first charging pile group E3, and another second insulating member 4b is located between the third electrode plate 70 and the first charging pile group E3. The present invention can also adjust the number of first insulating members 4a and second insulating members 4b according to actual needs, which is not a limitation of the present invention.

[0116] In one embodiment of the present invention, the shunt fuel cell device 100 further includes a first sealing element 5a and a second sealing element 5b to increase the airtightness of the chamber S of the housing 40. The first sealing element 5a is located between the first electrode plate 50 and the first charging pile group E3.

The present invention can also adjust the number of the first sealing element 5a and the second sealing element 5b according to actual needs, which is not a limitation of the present invention.

[0117] The shunt fuel cell device 100 further includes a third seal 5c and a fourth seal 5d to further increase the airtightness of the chamber S of the housing 40. The third seal 5c is located between the porous substrate 10 and the first electrode plate 50. The fourth seal 5d is located between the porous substrate 10 and the fourth electrode plate 80. The number of the third seal 5c and the fourth seal 5d can be adjusted according to actual needs, which is not a limitation of the present invention.

[0118] In one embodiment of the present invention, a plurality of conductive elements 30 each have a first series connection portion 32 and a second series connection portion 33, providing a connection between the plurality of conductive elements 30. The plurality of first series connection portions 32 and the plurality of second series connection portions 33 are respectively located at opposite ends of the plurality of conductive elements 30. The first series connection portion 32 of one conductive element 30 is disposed on the second series connection portion 33 of another conductive element 30, so that the plurality of conductive elements 30 are sequentially connected in series, thereby forming a columnar shape. The mounting area 31 is formed between each of the first series connection portions 32 and each of the second series connection portions 33, that is, through the groove between the first series connection portions 32 and the second series connection portions 33, a shunt section 22 of the coil 20 is provided.

[0119] Multiple first connecting portions 32 protrude from one end of multiple conductive members 30, forming a protruding end. Multiple second connecting portions 33 are recessed into the multiple conductive members 30 at the other end, forming a recessed end. The protruding end is selectively inserted into the recessed end. The first connecting portion 32 rotates into the internal thread of the second connecting portion 33 with its external thread.

[0120] In summary, the present invention has the following technical features:

[0121] 1. The shunt section 22 of the coil 20 of the present invention can shunt the current carrying capacity to improve the current carrying capacity of the present invention.

[0122] Second, the present invention provides multiple coil 20 shunt sections 22, which can further enhance the current carrying capacity. Furthermore, under the condition of maintaining the same current carrying capacity, coils 20 with smaller wire diameters can be used.

[0123] Third, in this invention, the current shunt section 22 of the coil 20 is tightly wound around the mounting area 31 in the form of two intersecting wires. In this way, the current shunt section 22 can be wound more stably around multiple conductive parts 30.

[0124] Fourth, this invention uses a tubular porous substrate 10 to diffuse gas from the tube to the reaction layer 11, allowing the gas to react completely in the reaction layer 11, thereby improving reaction efficiency. Furthermore, this invention can also use the porous substrate 10 for heat conduction, further reducing the temperature.

[0125] Fifth, the water produced during the gas and ion exchange reaction will be discharged from the surface of the porous substrate 10, thus avoiding the water from affecting the gas and ion exchange reaction and further improving the reaction efficiency.

[0126] VI. When gas is introduced into chamber S, the present invention can remove the heat energy from chamber S of the housing 40 through the interconnected first inlet zone R2, second exhaust zone R4, and reaction zone R5. Furthermore, this feature also allows water generated by the shunt fuel cell device 100 to be discharged through the second exhaust zone R4, preventing water from affecting the gas and ion exchange reactions.

[0127] 7. The first insulating member 4a and the second insulating member 4b of the present invention can further block objects of different polarities.

[0128] 8. The first sealing element 5a and the second sealing element 5b of the present invention can further enhance the airtightness of the chamber S of the housing 40. Furthermore, they can be used in conjunction with the third sealing element 5c and the fourth sealing element 5d to further increase airtightness.

[0129] The foregoing technical features do not preclude the existence of other features. Features that can be derived by those skilled in the art from the description, claims, or drawings of this invention are also included in the features of this invention.
