The complete decal transfer of
both electrodes onto the Nafion membrane under pressure as
low as 1.0 MPa (Fig. 2(b)) attests to the superiority of this rollpress
method for the release of catalyst layers from the substrate
films. The pressure range of the current method to
deliver a high catalyst transfer rate is 8e35 times lower than
that of the conventional low-temperature decal processes
[11,23,24]. No other reports on the decal methods are found in
the literature as efficient as this one for transferring catalyst
layers at such low pressures in the fabrication of MEAs for
DMFCs.
