Structural changes
of the MEAs due to different roller speeds were further
analyzed by full-cell and anode EIS measurement, as shown in
Fig. 11(b) and (c), respectively. The values for individual resistances
are listed in Table 2. Ohmic resistance decreases
with increasing roller speed. The anodic charge transfer
resistance of the MEA made at 50 mm min1 is significantly
lower than that of the other two while there is no noticeable
difference in the cathode charge transfer resistance.
