Problems solved by technology
[0006] In the existing hot pressing forming process for the production of fuel cell membrane electrodes, there are problems of poor hot pressing quality and low hot pressing accuracy
Among them, most of the existing hot-pressing operations are one-time molding, which is prone to uneven pressure or excessive pressure, and the glue is prone to sticking during the curing process; and it cannot ensure that the parts to be hot-pressed are easy to take and place At the same time, there will be no deviation during the hot pressing process, and the way of using the upper and lower pressing plates to stick white cardboard to carry out flat hot pressing on the membrane electrode assembly cannot ensure that the air bubbles in the membrane electrode assembly are completely removed.

Description
technical field [0001] The invention relates to the field of fuel cells, in particular to a device for continuous packaging of fuel cell membrane electrode sealing assemblies. Background technique [0002] Membrane electrode assemblies, or MEA (Membrane Electrode Assemblies), are the core components of hydrogen fuel cells, which are composed of the catalytic electrode layer of the hydrogen fuel cell and the gas diffusion layers located on both sides of the catalytic electrode layer. In the prior art, the hydrogen fuel cell membrane electrode assembly is formed by hot pressing the catalytic electrode layer membrane electrode and the gas diffusion layer located on both sides of the catalytic electrode layer membrane electrode, and the effect of hot pressing directly affects the quality of the membrane electrode assembly Among them, when the membrane electrode assembly is hot-pressed, the bubbles and wrinkles generated have the most serious impact on the membrane electrode asse...
