Abstract EN
The proton conductivity of Nafion 112, 1035, 1135, 115, and 117 membranes has been studied.
Measurements were made in 1 M H2SO4 at 298 K using a four-electrode, dc technique.
The membrane area resistance increases with thickness, and it was 0.065, 0.092, 0.076, 0.115, and 0.13 Ω.
cm2 for Nafion 112, 1035, 1135, 115, and 117 membranes respectively.
The results also showed that the proton conductivity of Nafion 112, 1035, 1135, 115, and 117 membranes was 0.09, 0.11, 0.10, 0.13, and 0.16 S.cm-1 respectively.
In the PEM fuel cell applications, it was observed that the optimum Nafion ionomer wt.% requirement does not change with the membrane thickness and the membrane EW.
In addition, the Nafion 1035 membrane can remain hydrated for longer than the Nafion 1135, or Nafion 112 membranes because it’s EW is (1000) lower than the Nafion EW of Nafion 1135 (1100), and Nafion 112 (1100).
In other words, a higher performance, more stable, and longer life PEM fuel cell can be obtained by using Nafion 1035 membrane as a solid electrolyte especially for high operating temperature.
