3.2.1. Scrutiny of a workable temperature domain
Adequate temperature during hot-pressing for decal transfer
of electrodes is one of the most critical factors, as it not only
greatly influences the degree of catalyst transfer but MEA
performance as well. Temperature values usually employed
for the decal technique range from 140 C (low-temperature
decal method) to about 200 C (high-temperature decal
method) [13,16,26].
