ABSTRACT:
The present invention provides a method for producing a membrane and electrode assembly (MEA) of a fuel cell, the method comprising: forming a composition for forming a catalyst layer by mixing a polymer ionomer, an alcohol solvent, and a polar organic solvent having a boiling point of 30 to 200° C. with a metal catalyst; coating the composition for forming a catalyst layer on both surfaces of a polymer electrolyte membrane to form electrode catalyst layers; and arranging electrode supports on the electrode catalyst layers. Also, the present invention provides an MEA of a fuel cell that is produced according to the method and a fuel cell comprising MEA of a fuel cell.
