Description

Technical Field

[0001] The invention relates to the technical field of combustion cell accessories, in particular to a fuel cell catalyst filling device. 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. It is the fourth power generation technology after hydroelectric power generation, thermal power generation, and atomic power generation. Since fuel cells convert part of the Gibbs free energy in the chemical energy of a fuel into electrical energy through electrochemical reactions, they are not limited by the Carnot cycle effect and therefore have high efficiency. In addition, fuel cells use fuel and oxygen as raw materials and have no mechanical transmission parts, so they emit very little harmful gas and have a long service life. It can be seen that from the perspective of energy conservation and ecological protection, fuel cells are the most promising power generation technology.

[0003] The core component of the fuel cell is the membrane electrode. In order to better exert the performance of the membrane electrode, before the membrane electrode is prepared, the catalyst needs to be filled on both sides of the proton exchange membrane to form a catalyst layer. However, the existing filling device often fills unevenly, resulting in different thicknesses of the catalyst layer on both sides of the membrane electrode, which not only affects the material and charge transfer process inside the catalyst layer, but also affects the size of the catalytic active area in the catalyst layer. Therefore, it is very necessary to design a fuel cell catalyst filling device to solve the above technical problems. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-4 A fuel cell catalyst filling device includes a clamping assembly 1, an electric slide 2, a limiting groove 3, a track 4, a membrane electrode 5, a flip track 6, and a filling pool 7.

[0025] Among them, it includes a clamping component 1, an electric slide 2 is provided at the bottom of the clamping component 1, a limiting groove 3 is provided at the top, the electric slide 2 cooperates with the track 4, the limiting groove 3 cooperates with the membrane electrode 5, a flip track 6 is provided on the track 4, and a filling pool 7 is provided at the corresponding position below the flip track 6.

[0026] Specifically, the membrane electrode 5 is placed in the limiting groove 3 to fix the position of the membrane electrode 5, and the electric slide 2 is started remotely to slide on the track 4. When the electric slide 2 slides to the flip track 6, the electric slide 2 flips, and the membrane electrode 5 flips with the electric slide 2. A filling pool 7 is provided at the corresponding position below the flip track 6. During the flipping process of the membrane electrode 5, it is in full contact with the catalyst stock solution in the filling pool 7, and both sides of the membrane electrode 5 are completely coated with the catalyst stock solution, thereby achieving the purpose of uniformly filling the catalyst stock solution on both sides of the membrane electrode 5 with consistent thickness.

[0027] In order to realize the sliding of the membrane electrode 5 on the track 4, in the technical solution of the present application, the electric slide 2 includes an electric slider 8, a bottom plate 9 is provided on the top of the electric slider 8, and side plates 10 are symmetrically provided on both sides of the bottom plate 9. The side plates 10 are snap-fitted with the bottom plate 9, and a limiting groove 3 is provided on the side plate 10. A matching groove 11 is provided on the track 4, and the matching groove 11 cooperates with the electric slider 8.

[0028] Specifically, after the side plate 10 corresponding to the size of the membrane electrode 5 is snap-fitted with the bottom plate 9, the membrane electrode 5 is placed in the limiting groove 3, and the side plates 10 on both sides clamp and fix the membrane electrode 5. After the clamping assembly 1 is started, the electric slider 8 slides in the matching groove 11, thereby driving the membrane electrode 5 to slide on the track 4.

[0029] In order to evenly fill the catalyst on both sides of the membrane electrode 5, in the technical solution of the present application, the flip angle of the clamping assembly 1 passing through the flip track 6 is 0-180 degrees. When the clamping assembly 1 is flipped to 180 degrees, the limiting groove 3 is located below the liquid surface in the filling pool 7.

[0030] Specifically, the clamping component 1 starts to slide on the track 4a, and reaches the flip track 6a after sliding for a distance. As the clamping component 1 slides, when passing the flip track 6a, the flip angle of the clamping component 1 is 0-180 degrees. When the clamping component 1 flips to 180 degrees, it reaches the track 4b. When sliding on the track 4b, the limit groove 3 is located below the liquid surface in the filling tank 7, so that the membrane electrode 5 is located below the liquid surface in the filling tank 7, and is in full contact with the catalyst stock solution in the filling tank 7. Both sides of the membrane electrode 5 are completely coated with the catalyst stock solution. As the clamping component 1 continues to slide, the clamping component 1 reaches the flip track 6b. When passing the flip track 6b, the flip angle of the clamping component 1 gradually returns from 180 degrees to 0 degrees. The clamping component 1 drives the membrane electrode 5 to gradually detach from the filling tank 7 and enter the next process. At this time, both sides of the membrane electrode 5 are completely and evenly coated with the catalyst stock solution, thereby achieving the purpose of evenly filling the catalyst on both sides of the membrane electrode 5.

[0031] In order to make the catalyst stock solution after uniform filling quickly solidify on the membrane electrode 5, in the technical solution of the present application, an oven 12 is provided on one side of the filling pool 7, and the track 4 runs through the oven 12. When the membrane electrode 5 gradually separates from the filling pool 7 and reaches the track 4c, as the clamping assembly 1 slides, the clamping assembly 1 drives the membrane electrode 5 into the oven 12 for drying. After the drying is completed, the clamping assembly 1 drives the membrane electrode 5 to slide into the next process, thereby achieving the purpose of making the catalyst stock solution after uniform filling quickly solidify on the membrane electrode 5.
