METHOD OF MANUFACTURING MEMBRANE ELECTRODE ASSEMBLY FOR SOLID POLYMER WATER ELECTROLYSIS

摘要

A method for preparing a membrane electrode assembly for solid polymer electrolysis is provided to allow uniform application of a catalyst onto a diffusion layer, and to increase the adhesion between a catalyst layer and a diffusion layer. A method for preparing a membrane electrode assembly for solid polymer electrolysis comprises: a step(S1) of forming an electrode solution containing a catalyst, binder resin and organic solvent; a step(S2) of transferring the electrode solution to a diffusion layer by a gas dynamic spray process to form a catalyst layer on the diffusion layer; and a step(S3) of carrying out hot fusion of the diffusion having the catalyst layer with an electrolyte membrane to provide a membrane electrode assembly.
