Abstract:
1. A method of manufacturing a membrane-electrode assembly for a fuel cell, the method comprising: spray-coating a binder on a surface of a polymer film; placing an electrolyte membrane on the binder-coated polymer film and then heating and compressing them to bond the electrolyte membrane to the polymer film by the binder; coating a catalyst slurry on a surface of the electrolyte membrane to form a catalyst electrode layer; separating a bonded assembly of the electrolyte membrane and the catalyst electrode layer from the polymer film, after a drying process, to obtain a 2-layer membrane-electrode assembly; and stacking two of the 2-layer membrane-electrode assemblies such that the electrolyte membranes thereof face each other and then heating and compressing them to form a 3-layer membrane-electrode assembly.
