Description

Technical Field

[0002] The membrane electrode is the site of multiphase material transmission and electrochemical reaction in the fuel cell, which determines the performance, life and cost of the fuel cell. It is mainly made of an integrated catalyst, proton exchange membrane, gas diffusion layer and frame. When making the membrane electrode, packaging treatment is required to increase the service life of the membrane electrode.

[0003] The prior art discloses patent application number "CN202221734472.6", a seven-in-one membrane electrode packaging fixture, including an upper packaging pressure plate provided with an upper vacuum adsorption flow channel and an upper groove, and a lower packaging pressure plate provided with a lower vacuum adsorption flow channel and a lower groove. The upper groove and the lower groove are positioned corresponding to each other and when interlocked, they jointly form a receiving cavity for placing the seven-in-one membrane electrode. When the upper vacuum adsorption flow channel and the lower vacuum adsorption flow channel are working, the seven-in-one membrane electrode is vacuumed through low pressure.
