Abstract

In our work the through-plane and in-plane conductivity measurements were performed for commercial Nafion115 and original sulphonated poly(ether-ether-ketone) (SPEEK) membranes. It was found, that in-plane conductivity measurement method can be successively used for both types of membranes at maximal humidity (saturated water vapours) and temperatures till 100°C. The proton conductivities of home-made SPEEK membranes were found to be excellent in the order of 10−2 S/cm in the fully hydrated condition at temperatures 25−90°C.
