Description

Technical Field

[0001] This invention relates to the field of fuel cell technology, specifically to a manufacturing process for a CCM sample membrane for fuel cells. Background Technology

[0002] Currently, proton exchange membranes for fuel cells are mainly made of imported materials, while membrane electrode assembly (CCM membrane and GDL assembly) is carried out domestically. Due to the high cost of CCM membrane manufacturing and the extremely expensive production equipment, a similar structural sample membrane is needed for debugging. Therefore, we propose a manufacturing process for CCM sample membranes for fuel cells to produce CCM sample membranes. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a manufacturing process for CCM sample membranes for fuel cells, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A manufacturing process for a CCM sample membrane for fuel cells includes the following steps:

[0007] S1: Weigh an appropriate amount of water-based acrylic resin emulsion, ethanol and a portion of deionized water, add them to the dispersion vessel, and mix and disperse them thoroughly.

[0008] S2: Add an appropriate amount of carbon black and defoamer into the dispersion vessel in S1, and disperse and stir thoroughly until uniform;

[0009] S3: Transfer the well dispersed material from S2 into a sand mill and grind it to an appropriate degree;

[0010] S4: Transfer the ground material from S3 to the dispersion vessel, and add appropriate amounts of 831 emulsion, 824 emulsion, water-based wax, propylene glycol butyl ether, defoamer and deionized water to the dispersion vessel. After sufficient dispersion and stirring, a water-based ink with a light transmittance of less than 0.1% is prepared.

[0011] S5: Using a coating device, the water-based ink prepared in S4 is uniformly coated onto a film substrate of a certain thickness and with a light transmittance greater than 92% to produce a CCM sample functional film with a specific shape. The CCM sample functional film with a specific shape consists of a water-based ink layer and a film substrate layer.

[0012] S6: Formulate a resin adhesive with special bonding properties;

[0013] S7: Using a coating device, the resin adhesive obtained in S6 is applied to the film substrate to form an ultra-thin coated adhesive functional film, which consists of a resin adhesive layer and a film substrate layer.

[0014] S8: Remove the protective layer of the resin adhesive layer on the surface of the ultra-thin coated adhesive functional film prepared in S7, so that the resin is exposed.

[0015] S9: Using a shaping device, the resin adhesive layer with the protective layer removed from the ultra-thin coated adhesive functional film prepared in S8 and the water-based ink layer of the CCM sample functional film of a specific shape prepared in S5 are shaped under a certain pressure to obtain a CCM sample membrane for fuel cells. The CCM sample membrane for fuel cells includes a thin film substrate layer, a resin adhesive layer, a water-based ink layer and a thin film substrate layer arranged from top to bottom.

[0016] S10: Use a cutting device to cut the product shaped in S9 to obtain a product with specific size requirements;

[0017] S11: Perform electrical discharge treatment on the surface of the product obtained in S10.

[0018] Furthermore, after the material in S3 is ground, the grinding fineness of the material needs to be measured. The grinding fineness of the material is 5 to 15 μm.

[0019] Furthermore, the rotation speed of the dispersion vessel in S1, S2 and S3 is 300-500 r / min.

[0023] Furthermore, removing the protective layer from the surface of the ultrathin coating adhesive functional film in S8 requires the use of roll-to-roll winding equipment.

[0024] Furthermore, the shaping equipment in S9 is either a die-cutting machine or a laminating machine, with a laminating pressure of 0.1 to 0.5 MPa.

[0025] Furthermore, the cutting equipment in S10 is either a slitting machine or a die-cutting machine, with a dimensional control deviation of ±0.5mm.

[0026] Furthermore, the discharge treatment in S11 is a corona discharge or plasma treatment.
