Linear and Nonlinear Viscoelastic Characterization of Proton Exchange Membranes and Stress Modeling for Fuel Cell Applications
… properties of a PEM are important for making hygrothermal stress predictions in the cyclic temperature and humidity environment of operating fuel cells. In this study, Nafion® NRE 211, Gore-Select® 57, and Ion Power® N111-IP were characterized under various humidity and temperature conditions. …

Experimental Studies on the Mechanical Durability of Proton Exchange Membranes
… biaxial strength of PEMs and the biaxial hygrothermal stresses that occur in PEMs during hygrothermal cycles. The third method investigated the nonuniform thickness and compressibility of gas diffusion media which can lead to concentrated compressive stresses in the PEM in the …
