Abstract

The invention relates to the field of fuel cells, in particular to a membrane electrode packaging structure and a packaging method. The membrane electrode packaging structure comprises a top surface gas diffusion layer and a bottom surface gas diffusion layer, a frame and a catalyst coating film which are mutually stacked are clamped between the two gas diffusion layers, the catalyst coating filmis bonded and fixed on the top surface of the frame, only one frame is arranged, the part, bonded with the catalyst coating film, of the top surface of the frame is concave, the catalyst coating filmis bonded on the bottom wall of the concave part, and the inner side wall of the concave part blocks the periphery of the catalyst coating film. The packaging structure can reduce the production costand reduce the air leakage risk of the sealing area.

Description

technical field

[0001] The invention relates to the field of fuel cells, in particular to a membrane electrode packaging structure and packaging method. Background technique

[0002] Such as figure 1 , the current mainstream packaging method for membrane electrodes is as follows: firstly, the anode catalyst layer and the cathode catalyst layer are respectively coated on both ends of the proton exchange membrane to prepare a catalyst-coated membrane 4 (CCM) with a three-layer structure; then the catalyst is coated The edges of the membrane 4 and the edges of the two frames 1 and 9 are bonded and sealed with an adhesive to form a five-layer assembly; the last two layers of gas diffusion layers 5 and 6 are respectively bonded to the frame by an adhesive to form a seven-layer assembly the membrane electrode.

[0003] Although the above double-layer frame membrane electrodes can meet the basic sealing requirements, they have the following two main disadvantages in large-scale m...
