Problems solved by technology

In the process of using the split frame, it is easy to cause relative misalignment, resulting in inconsistency between the position of the frame on both sides and the contact between the frame and the membrane electrode, which directly leads to uneven force on both sides of the membrane electrode and damage to the membrane electrode.

Abstract

The invention discloses a frame, a membrane electrode assembly and membrane electrode assembly preparation equipment, and belongs to the technical field of fuel cells. The frame comprises: a first frame part and a second frame part, wherein the first frame part and the second frame part are integrally formed; an accommodating cavity which is formed between the first frame part and the second frame part and allows a workpiece to be inserted, wherein the first frame part comprises a first flow channel allowing an adhesive to enter, and the first flow channel is communicated with the containing cavity, the second frame part comprises a second flow channel allowing the binder and the air to flow out, and the second flow channel is communicated with the containing cavity. By means of the integrated frame, the problem that in the using process of a split frame, relative dislocation is likely to be caused, and consequently the positions of the frames on the two sides and the contact between the frame and the membrane electrode are inconsistent is solved.

Description

Technical field [0001] The present invention belongs to the technical field of fuel cells, and more particularly to a border, membrane electrode assembly, and film electrode assembly preparation apparatus. Background technique [0002] In the prior art, a film electrode is prepared, which is generally used in a set of bodes that are separately set. In the process of use, the partial border is easily contrary to the relative misalignment, and the contact between the border position between the sides and the frame and the film electrodes is not uniform, directly causes unevenness of the ends of the film electrode, and the film electrode is damaged. Therefore, how to ensure the consistency of the bonding of the membrane electrode to become an urgent need to solve. Inventive content [0003] In order to solve the technical problem in the above background, a border, membrane electrode assembly, and film electrode assembly are provided. [0004] The present invention adopts the follow...
