Embodiment 1

[0046] Example 1: Preparation of seven-in-one membrane electrode with a clamp without gas flow channel. The bottom plate is fixed in the dispenser, and the dispenser is programmed according to the fixed position. After the program is set, place the gas diffusion layer in the groove of the lower bottom plate and use a dispenser to dispense. After dispensing, spread the five-in-one membrane electrode on the gas diffusion layer along the location of the positioning hole, and lightly press the dispensing position before performing the dispensing operation. After dispensing, press the positioning frame along the positioning hole on the membrane electrode. Then spread another gas diffusion layer on the membrane electrode along the inner edge of the positioning frame, and finally press the upper cover plate flat on the gas diffusion layer. Put the whole set of clamps on the press and press for a certain time under a certain pressure, and then take out the sample to obtain the seven-...

Embodiment 2

[0047] Example 2: Using the fixture of the present invention to prepare a seven-in-one membrane electrode, the bottom plate is fixed in the dispenser, and the dispenser is programmed according to the fixed position. After the program is set, place the gas diffusion layer in the groove of the lower bottom plate and open the vacuum adsorption device, and then use the dispenser to dispense. After the dispensing is completed, the five-in-one membrane electrode is laid flat on the gas diffusion layer along the positioning hole and the dispensing operation is performed. After dispensing, press the positioning frame along the positioning hole on the membrane electrode. Then spread another gas diffusion layer on the membrane electrode along the inner edge of the positioning frame, and finally press the upper cover plate flat on the gas diffusion layer to close the vacuum adsorption device. Put the whole set of clamps on the press and press for a certain time under a certain pressure, ...

Abstract

The invention provides a seven-in-one membrane electrode packaging clamp and a proton exchange membrane fuel cell. The seven-in-one membrane electrode packaging clamp comprises an upper cover plate (1) and a lower bottom plate (4). A groove (41) is arranged in the lower bottom plate (4). A size and a shape of the upper cover plate (1) is matched with those of the groove and the upper cover plate can be arranged in the groove (41). The groove (41) can bear a seven-in-one membrane electrode, the upper cover plate (1) can cover the seven-in-one membrane electrode, a vacuum adsorption flow channel(42) is arranged in a bottom surface, bearing the seven-in-one membrane electrode, of the groove (41), and the seven-in-one membrane electrode can be adsorbed and positioned through low pressure whenthe vacuum adsorption flow channel (42) works. In the invention, the seven-in-one membrane electrode located on a base plate can be adsorbed in a vacuumizing manner so that a positioning effect is effectively achieved, positioning precision is improved, positioning and fixing capabilities are good, assembling time is saved, and a yield is improved.

Description

Technical field [0001] The invention belongs to the technical field of fuel cells, and specifically relates to a seven-in-one membrane electrode packaging fixture and a proton exchange membrane fuel cell. Background technique [0002] In order to facilitate access to the membrane electrode during use, and to improve work efficiency, Metropolis will combine a five-in-one membrane electrode (a proton exchange membrane with a catalyst attached and a sealing edge) together with a cathode and anode gas diffusion layer. That is to form a seven-in-one membrane electrode. At present, most gas diffusion layers are made of carbon paper as the base material and have a hydrophobic layer and a microporous layer attached to the carbon paper. However, the carbon paper is relatively brittle. If the force is uneven during the preparation of the seven-in-one membrane electrode, it is easy to cause the carbon paper Shattered. At the same time, the dimensional accuracy of the combination of the ga...
