摘要:
A process for manufacture of integrated membrane-electrode-assemblies (MEAs), which comprise an ionomer membrane, at least one gas diffusion layer (GDL), at least one catalyst layer deposited on the GDL and/or the ionomer membrane, and at least one protective film material is disclosed. The components are assembled together by a lamination process comprising the steps of heating the components to a temperature in the range of 20 to 250° C. and laminating the materials by applying a laminating force in the range of 50 to 1300 N with a pair of rolls. The claimed lamination process is simple and inexpensive and is used for manufacture of advanced, integrated MEAs for electrochemical devices such as PEM fuel cells and DMFC.
