Proton conductivity of the membranes in plane direction (\2\2)
was measured using an electrochemical impedance spectroscopy
technique over the frequency range from 10 Hz to 100 KHz (Hioki
3532-50).A single cell with two blackened platinum plate electrodes
was mounted on a Teflon plate at 0.5cm distance.The cell
was placed in either a thermo-controlled humidic chamber or deionized
water to measure the proton conductivity as functions of
relative humidity (RH) and temperature.Proton conductivity \2 was
calculated from Eq.(1):
\2 = d
(tswsR)
(1)
where d is the distance between the two electrodes,ts and ws are
the thickness and width of the membrane at a standard condition of
60% RH,respectively,and R is the resistance value measured.For the
measurement in liquid water,the swollen membrane thickness was
used in the calculation of \2.During the measurement above 100 ◦C
at 100% RH,a pressure-resistant (up to 7 bar) closed chamber was
used.
