Abstract

The mechanical stability of modified membranes has become a priority for fuel cell applications as the membranes must endure all the fuel cell operations (to prevent crossover of the fuel while still conducting). Their mechanical stress and yielding stress in the recast and impregnation methods compared with the commercial Nafion® membrane were observed under tensile tests. The modulus of elasticity of wet commercial Nafion117 membrane, Nafion®/ Zr-0, Nafion®/Zr-50 and Nafion®/ Zr-80 membranes and Nafion®/ Zr-100 nano-composite membrane using impregnation methods in the region between 0 and 0.23 strain were determined to be 4817.5 kPa, 2434.7 kPa, 1872.4 kPa, 2092.1 kPa and 2661.4 kPa respectively. The tensile strength of the dry nano-composite membrane prepared using the recast method is higher than the wet nano-composite membrane prepared using the recast methods. It was found that the impregnation method plays an important role in strengthening the nan-composite membranes.
