Abstract
The hygro-thermo-mechanical properties and response of a class of reinforced perfluorosulfonic acid membranes (PFSA), that has potential application as an electrolyte in polymer fuel cells, are investigated through both experimental and numerical modeling means. A critical set of material properties, including Young’s modulus, proportional limit stress, break stress and break strain, is determined for a range of temperature and humidity levels in a custom-built environmental test apparatus. The swelling strains are also determined as functions of temperature and humidity level. To elucidate the mechanical response and the potential effect these properties have on the mechanical durability, mechanics-based simulations are performed using the finite element method (ABAQUS). The results indicate that the relatively high strength of the experimental membrane, in combination with its relatively low in-plane swelling due to water absorption, should have a positive influence on membrane durability, potentially leading to longer life times for polymer electrolyte membrane fuel cells (PEMFC).
