Description

Technical Field

[0001] This utility model relates to the field of fuel cell processing technology, specifically to a device for preparing electrodes for air-cooled fuel cells. Background Technology

[0002] Air-cooled fuel cells are a type of fuel cell that dissipates heat through natural air convection or forced airflow from a fan. They utilize an electrochemical reaction to directly convert the chemical energy of fuel (such as hydrogen) and oxidant (air) into electrical energy, while the air-cooling system removes the heat generated by the reaction, maintaining a stable cell temperature. The electrodes of an air-cooled fuel cell serve to support the electrochemical reaction and conduct matter and energy. Currently, the manufacturing method for fuel cell membrane electrodes involves sealing the proton exchange membrane within a protective frame. The protective frame uses 10-100µm PEN, a very thin and flexible material. The proton exchange membrane itself uses PEM, a material only 8-20µm thick, which readily absorbs moisture from the air. This thin and flexible material is also prone to deformation due to water absorption. Therefore, the production process is easily contaminated, deformed, and damaged. Air bubbles are also easily generated during the membrane application process, and the membrane is easily misaligned.

[0003] A fuel cell membrane electrode preparation device disclosed in Chinese patent document CN219435922U includes a worktable. Two guide rails are arranged on the worktable, and a slider is mounted on each guide rail. The slider moves freely on the guide rails, and an operating platform is mounted on the slider. The operating platform consists of an upper plate and a lower plate, which are shaped to fit each other and are fixedly connected by tightening bolts. Several vacuum adsorption holes are formed on the upper surface of the upper plate. The operating platform is driven by the slider to run on the guide rails. An air suction device is provided between the upper and lower plates to achieve a negative pressure effect within the vacuum adsorption holes. This device facilitates the positioning of PEN / PEM membranes, makes it easy to flatten the PEN / PEM membrane, and ensures that wrinkles do not occur during membrane application.

[0004] The aforementioned device uses an air suction device between the upper and lower plates to achieve a negative pressure effect within the vacuum adsorption pores, thereby flattening and positioning the PEN / PEM membrane on the upper plate. However, if the PEN / PEM membrane placed on the upper plate has large wrinkles, this method not only fails to achieve the flattening effect but also adsorbs the PEN / PEM membrane onto the upper plate in a wrinkled state. Therefore, a wind-cooled fuel cell electrode fabrication device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an apparatus for preparing processing electrodes for air-cooled fuel cells, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for preparing electrodes for air-cooled fuel cells, comprising a worktable, two guide rails at the upper end of the worktable, two sliders slidably connected to the two guide rails respectively, an operating platform on the four sliders, the operating platform consisting of a lower plate and an upper plate, an air suction device between the lower plate and the upper plate, a plurality of vacuum adsorption holes on the upper surface of the upper plate, a leveling mechanism on the worktable, the leveling mechanism consisting of a second U-shaped plate, a rotating shaft, a pressure roller, and a connecting mechanism acting on the second U-shaped plate, the two ends of the rotating shaft being rotatably connected to the two vertical plates of the second U-shaped plate respectively, a pressure roller being fixedly sleeved on the rotating shaft, and a connecting mechanism between the second U-shaped plate and the worktable.

The two second sliders are slidably connected to the two second guide rails respectively. The two ends of the first U-shaped plate are respectively fixedly connected to the two second sliders. A lifting adjustment mechanism is provided between the second U-shaped plate and the first U-shaped plate.

[0009] As a further preferred embodiment of this technical solution, the lifting and adjusting mechanism includes two cylinders, which are respectively fixedly installed on the upper end of the first U-shaped plate. The telescopic rod of the cylinder slides through the first U-shaped plate and is fixedly connected to the upper end of the second U-shaped plate.

[0010] As a further preferred embodiment of this technical solution, a handle is also fixedly installed on one side of the upper end of the first U-shaped plate, and the outer surface of the handle is frosted.

[0011] As a further preferred embodiment of this technical solution, the first slider is provided with a positioning pin.

[0012] As a further preferred embodiment of this technical solution, baffles are fixedly connected to both sides of the workbench.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, an apparatus for preparing processed electrodes for an air-cooled fuel cell includes a worktable 1. Two guide rails 3 are provided on the upper end of the worktable 1. Two sliders 4 are slidably connected to the two guide rails 3. An operating platform 2 is provided on the four sliders 4. The operating platform 2 consists of a lower plate 13 and an upper plate 14. An air suction device is provided between the lower plate 13 and the upper plate 14. The lower plate 13 and the upper plate 14 are fixedly connected by four tightening bolts, which are distributed at the four corners of the operating platform 2. Several vacuum adsorption holes 15 are provided on the upper surface of the upper plate 14. A leveling mechanism is also provided on the worktable 1. The leveling mechanism consists of a second U-shaped plate 9, a rotating shaft 10, a pressure roller 11, and a connecting mechanism acting on the second U-shaped plate 9. The two ends of the rotating shaft 10 are rotatably connected to the two vertical plates of the second U-shaped plate 9. The pressure roller 11 is fixedly sleeved on the rotating shaft 10. A connecting mechanism is provided between the second U-shaped plate 9 and the worktable 1.

[0022] The connecting mechanism consists of a second guide rail 5, a second slider 6, and a first U-shaped plate 7. The two second guide rails 5 are fixedly installed on the upper end of the workbench 1. The two second guide rails 5 are located on the opposite side of the two first guide rails 3. The second sliders 6 are slidably connected to the two second guide rails 5. The two ends of the first U-shaped plate 7 are fixedly connected to the two second sliders 6. A lifting adjustment mechanism is provided between the second U-shaped plate 9 and the first U-shaped plate 7.

[0023] The lifting and adjusting mechanism includes two cylinders 8. The two cylinders 8 are fixedly installed on the upper end of the first U-shaped plate 7. The telescopic rod of the cylinder 8 slides through the first U-shaped plate 7 and is fixedly connected to the upper end of the second U-shaped plate 9.

[0024] In use, the height of the second U-shaped plate 9 can be controlled by the cylinder 8, thereby controlling the height of the pressure roller 11, so that the distance between the pressure roller 11 and the operating platform 2 reaches a suitable value.

[0025] Among them, a handle 12 is fixedly installed on one side of the upper end of the first U-shaped plate 7, and the outer surface of the handle 12 is frosted.

[0026] Workers can hold handle 12 to move the first U-shaped plate 7.

[0032] When in use, after the PEN / PEM film is placed on the operating platform 2, the handle 12 can be held to move the first U-shaped plate 7 so that the first U-shaped plate 7 passes through the top of the operating platform 2. The pressure roller 11 under the first U-shaped plate 7 can flatten the PEN / PEM film on the operating platform 2. Then, the suction device can achieve the effect of negative pressure in the vacuum adsorption hole 15, thereby stabilizing the flattened PEN / PEM film and keeping it in a flat state.
