Abstract

The present invention relates to a method for manufacturing a membrane electrode. The method for manufacturing the membrane electrode comprises the following steps of unwinding and outputting a firstframe material belt to pass through a first pressing station; unwinding and outputting a CCM material belt to pass through the first pressing station; and at the first pressing station, pressing the CCM material belt and the first frame material belt to form a first composite material belt, and bonding the CCM units to a first active area of a first frame layer one by one through a first bonding glue layer, and separating from a back film. Compared with the prior art that the CCM material belt and the frame material belt are manufactured into the sheet materials and are flatly pressed to be compounded, the CCM units are transferred to the first active area of the first frame layer in a roll-to-roll manner, so that the production efficiency is improved, and the capacity requirement is better met.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a method for manufacturing a membrane electrode. Background technique [0002] Membrane electrode (MEA, Membrane Electrode Assemblies) is composed of CCM (Catalyst Coated Membrane), cathode and anode frame, cathode and anode GDL (gas diffusion layer). [0003] The traditional manufacturing method is the production of composite sheets, that is, the CCM, frame and GDL are made into sheets by sheet-making technology, and then the frame and CCM are assembled into a composite sheet by flat pressing, and then the cathode GDL and GDL are assembled into sheets. The anode GDL is pasted on opposite sides of the combined sheet material respectively, so as to obtain the finished membrane electrode. However, the production efficiency of the method of compounding sheet materials is low and cannot meet the production capacity demand. Contents of the invention [0004] Based on this, it i...
