A method for fabricating a membrane-electrode assembly, and fuel cells
adopting a membrane-electrode assembly formed by the method, wherein the
method includes: coating nano-sized catalytic metal particles on a proton
exchange polymer membrane by sputtering a catalytic metal source; coating
nano-sized carbon particles on the proton exchange polymer membrane by arc
discharging or by sputtering a carbon source to form a nanophase catalyst
layer; and bonding electrodes to the proton exchange polymer membrane
having the nanophase catalyst layer. The nano-sized catalytic metal and
nano-sized carbon particles can be coated on a proton exchanger polymer
membrane to form a catalyst layer by simultaneously sputtering a catalyst
metal source and a carbon source.
