Abstract

The invention relates to the technical field of fuel batteries, and discloses a preparation method and a preparation device for a fuel battery catalyst coating film. The preparation method for the fuel battery catalyst coating film comprises following steps of: coating a side A of a proton exchange film, and coating a side B of a transfer medium film; stoving the proton exchange film, and stovingthe transfer medium film; winding to remove a back film of the proton exchange film; aligning and pressing the transfer medium film and the proton exchange film; hot pressing the transfer medium filmand the proton exchange film, and winding the transfer medium film and a catalyst coating film. Through adoption of the preparation method and the preparation device for the fuel battery catalyst coating film, two sides can be coated simultaneously, a coating machine and a hot press are used jointly, the back film of the proton exchange film can be removed automatically, and the preparation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a new method for preparing fuel cell catalyst coating membranes. Background technique [0002] Commercial fuel cell proton exchange membranes on the market usually consist of two parts, namely the proton membrane and the protective backing film. The protective backing film plays the role of protection and substrate, so the proton membrane part can only be coated on one side and dried alone, and cannot Using a common double-sided coating machine, if the protective backing film is torn off, the proton membrane will be relatively soft and easily deformed. Therefore, the prior art can only consider coating first and then removing the protective backing film, resulting in low production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide and solve the problem in the prior art that only one side of the proton exchange membrane can be c...
