Summary In this work, two different polymer membrane systems based on Nafion and Teflon were investigated as proton conductors for polymer membrane fuel cells. Water-free Nafion117 membranes swollen with different non-aqueous solvents were prepared. The solvents included imidazole, imidazole–imidazolium salt solutions, room temperature molten salts and molten salt–acid solutions. Teflon films were treated with a surfactant, or a Nafion solution, to improve their surface properties, and were subsequently swollen with phosphoric acid. Conductivity measurements were carried out on both the Nafion and Teflon membranes. Conductivities in the range of 10−3 S cm−1 at around 100°C were obtained. This is still an order of magnitude lower than the corresponding water swollen Nafion at 80°C.
