Description

Technical Field

[0001] The utility model relates to the field of fuel cells, in particular to a novel mobile drying device for bipolar plates of fuel cells. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy, also known as an electrochemical generator. A fuel cell uses fuel and oxygen as raw materials and has no mechanical transmission parts, so it emits very little harmful gas and has a long service life.

[0003] The common technical means for processing fuel cell graphite bipolar plates are currently precision carving and molding. Both methods will inevitably produce a lot of graphite debris during the processing. Before formally assembling into a fuel cell stack, each graphite bipolar plate needs to be cleaned one by one, and then dried before assembly.

[0004] Traditional methods of drying bipolar plates include spreading them out to dry and drying them in an oven. Spreading them out to dry requires a lot of space, and the water under the bipolar plates is not easy to evaporate, so the bipolar plates need to be turned over many times. Oven drying consumes a lot of energy and has low efficiency. At the same time, the bipolar plates are easily deformed by uneven heating, which has certain defects. Utility Model Content

[0005] The utility model aims to provide a novel mobile drying device for fuel cell bipolar plates, so as to achieve rapid drying of the fuel cell bipolar plates and prevent deformation of the fuel cell bipolar plates.

[0010] Further, the support rod assembly includes an outer support rod and an inner support rod;

[0024] The novel fuel cell bipolar plate mobile drying device of the utility model will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the utility model is shown, and it should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0026] like Figure 1 As shown, the embodiment of the utility model proposes a novel mobile drying device for fuel cell bipolar plates, including a back plate 1, a central partition plate 2 and a support rod assembly.

[0027] Specifically, the back plate 1 and the central partition plate 2 are arranged vertically, and the central partition plate 2 divides the back plate 1 into two drying areas 3.

[0028] The support rod assembly is fixedly mounted on the back plate 1 , and the support rod assembly is located in the drying area 3 .

[0029] The support rod assembly has a plurality of inclined support parts, and when the object to be dried is placed obliquely on the inclined support parts, the bottom end of the object to be dried contacts the central partition plate 2 .

[0030] In this embodiment, when the fuel cell bipolar plates need to be dried, the fuel cell bipolar plates are placed obliquely on the inclined support portion. When the number of fuel cell bipolar plates to be dried is large, the fuel cell bipolar plates can be stacked on the inclined support portion. Since the fuel cell bipolar plates are in an inclined state, the water on the fuel cell bipolar plates can fall along the inclined surface, greatly improving the drying efficiency of the fuel cell bipolar plates. In addition, during the drying process of the fuel cell bipolar plates, the central partition 2 supports and positions the bottom end of the fuel cell bipolar plates, which can provide safe and stable support for the fuel cell and reduce the risk of the fuel cell bipolar plates tilting and sliding.

[0031] Furthermore, the support rod assembly includes an outer support rod 4 and an inner support rod 5;

[0032] There are multiple outer support rods 4 and multiple inner support rods 5, and the outer support rods 4 and the inner support rods 5 are arranged vertically.

[0033] Specifically, the outer support rods 4 and the inner support rods 5 are evenly distributed on the back plate 1 , and the outer support rods 4 and the inner support rods 5 are vertically arranged to the back plate 1 .

[0034] In addition, the inner support rod 5 is close to one side of the central partition 2, and when the outer support rod 4 is higher than the inner support rod 5, the outer support rod 4 and the inner support rod 5 form an inclined support portion.

[0035] When the fuel cell bipolar plate is dried, the top of the fuel cell bipolar plate is in support contact with the outer support rod 4 on the inclined support part, and the bottom of the fuel cell bipolar plate is in support contact with the inner support rod 5 on the inclined support part. Since the outer support rod 4 of the inclined support part is higher than the inner support rod 5, the fuel cell bipolar plate is in an inclined support state. At the same time, the central partition 2 positions and supports the bottom of the fuel cell bipolar plate, so that the fuel cell bipolar plate can be stably placed on the inclined support part.

[0036] It should be noted that when multiple fuel cell bipolar plates need to be dried, the fuel cell bipolar plates can be stacked and placed on other inclined support parts. Since the fuel cell bipolar plates are stacked, there are gaps between the fuel cell bipolar plates, which facilitates the evaporation of water in the fuel cell bipolar plates.

[0037] In addition, if Figure 2 As shown, the inclination angle of the fuel cell bipolar plate can be adjusted according to actual needs. When the inclination angle required for drying the fuel cell bipolar plate is small, the top of the fuel cell bipolar plate can be placed on the first outer support rod 4 from top to bottom, and the bottom of the fuel cell bipolar plate can be placed on the second inner support rod 5 from top to bottom. Similarly, when a larger inclination angle is required, keep the top position of the fuel cell bipolar plate unchanged, and place the bottom of the fuel cell bipolar plate on the third and fourth inner support rods 5 from top to bottom, while ensuring that the fuel cell bipolar plate can be stably tilted and placed on the inclined support portion. The remaining fuel cell bipolar plates are stacked in sequence and placed below the first fuel cell bipolar plate.

[0038] Furthermore, at least one supporting boss 6 is disposed on the side surfaces of the back plate 1 and the central partition plate 2 located in the drying area 3 .

[0039] Specifically, Figure 3 As shown, during the tilted placement of the fuel cell bipolar plate, in order to avoid the side of the fuel cell bipolar plate from being in close contact with the back plate 1 and the center partition plate 2 and thus being unable to discharge moisture above the fuel cell bipolar plate, a supporting boss 6 is provided on the back plate 1 and the center partition plate 2, so that a gap can be created between the fuel cell bipolar plate and the back plate 1 and the center partition plate 2, thereby facilitating the discharge of moisture from the upper surface of the fuel cell bipolar plate and accelerating the drying of the fuel cell bipolar plate.

[0040] In order to avoid damage caused by collision between the fuel cell bipolar plate and the sharp part of the support boss 6, the cross-section of the support boss 6 is set to be an arc shape, so that the fuel cell bipolar plate can contact smoothly with the support boss 6, reducing the risk of damage caused by collision between the fuel cell bipolar plate and the support boss 6.

[0041] Furthermore, a bottom plate 7 is provided below the back plate 1 and the center partition plate 2 , and the bottom plate 7 is fixedly connected to the back plate 1 and the center partition plate 2 .

[0042] Specifically, in order to ensure the stability of the support of the back plate 1 and the central partition 2, a chassis 7 is provided below the back plate 1 and the central partition 2 to increase the support stability by increasing the support area.

[0043] In addition, in order to facilitate the movement of the drying device, a plurality of movable pulleys 8 are installed on the bottom surface of the chassis 7 .

[0044] Compared with the prior art, the utility model has at least the following beneficial effects:

[0045] The utility model dries the fuel cell bipolar plates by placing them at an angle, and can dry multiple fuel cell bipolar plates within a unit volume without turning the bipolar plates over, and can prevent moisture from being retained on the fuel cell bipolar plates, and has the characteristics of simple structure and convenient operation.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
