Preparation method of fuel cell membrane electrode with drainage pipeline acting structure

The invention belongs to the technical field of preparation of fuel cell membrane electrodes, and particularly relates to a preparation method of a fuel cell membrane electrode with a drainage pipeline acting structure, which comprises the following steps of: rolling two surfaces of a cathode catalyst layer and an anode catalyst layer by using a two-dimensional convex line arrangement structure roller with mutually connected surfaces; mutually communicated two-dimensional drainage pipeline structures are formed on the surface of the catalyst layer, and finally, the gas diffusion layer, the frame and the catalyst layer with the drainage pipeline structures are integrally formed to obtain the fuel cell membrane electrode with excellent electrochemical performance. The material transmission performance of the membrane electrode of the fuel cell is greatly improved, the two-dimensional drainage pipeline structures communicated with each other on the surface of the catalyst layer are similar to underground drainag
