TL;DR: In this paper, the mechanical response of fuel cell proton exchange membranes subjected to a single hygro-thermal duty cycle in a fuel cell assembly is investigated through numerical means, and the behavior of the membrane with temperature and humidity dependent material properties is simulated under temperature and moisture loading and unloading conditions.

TL;DR: In this article, the mechanical properties of a perfluorosulfonic acid (PFSA) membrane have been investigated at different humidities and temperatures in a custom-designed environmental chamber, where tensile tests were conducted to determine Young's modulus, the proportional limit stress (yield strength), break stress, and break strain.

TL;DR: In this paper, the authors explore how the instability of thermally grown oxide (TGO) is linked to constituent properties, such as oxidation of TGO, plastic flow of the bond coat, thermal expansion misfit between the TGO and bond coat and substrate, and stress relaxation in TGO at high temperature.

TL;DR: In this article, the mechanical response of proton exchange membranes in a fuel cell assembly is investigated under humidity cycles at a constant temperature (85°C), and the behavior of the membrane under hydration-dehydration cycles is simulated by imposing a humidity gradient from the cathode to the anode.

TL;DR: In this paper, the finite element method has been used to simulate the properties of panels with Kagome and tetragonal cores under compressive and shear loading, and the simulation has been performed for two different materials: a Cu-alloy with extensive strain hardening and an Al-aloy with minimal hardening.
