We have thoroughly investigated the roll-press-based decal
method for the fabrication of MEAs for use in DMFCs and
elucidated its distinctive advantages of process simplification
and productivity. This method ensures a complete transfer of
both anode and cathode electrodes onto a Nafion membrane
under pressure as low as 1.0 MPa at 140 C with an effective
hot-pressing duration of only a few seconds. The pressure
range of the current method to deliver a high catalyst transfer
rate is 8e35 times lower than the conventional decal processes
