RISThe Effect of Compressibility on the Stress Distributions in Thin Elastomeric Blocks and Annular Bushings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the bulk compressibility of elastomers on the response of rubber blocks and bushings bonded to platens is in vestigated. Closed-form solutions for the stresses and deformations ...
Viscoelastic Stress Analysis of Constrained Proton Exchange Membranes Under Humidity Cycling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many premature failures in proton exchange membrane (PEM) fuel cells are attributed to crossover of the reactant gas from microcracks in the membranes. The formation of these microcracks is ...
Strain Accumulation in Polymer Electrolyte Membrane and Membrane Electrode Assembly Materials During a Single Hydration/Dehydration Cycle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A digital image correlation technique was used to measure drying-induced strains in perfluorosulfonic acid (PFSA) membrane and membrane electrode assembly (MEA) materials which are key components ...
The Effect of Mechanical Fatigue on the Lifetimes of Membrane Electrode Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Long-term durability of the membrane electrode assembly (MEA) in proton exchange membrane (PEM) fuel cells is one of the major technological barriers to the commercialization of fuel cell vehicles. ...
On the Use of Pressure-Loaded Blister Tests to Characterize the Strength and Durability of Proton Exchange Membranes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of pressurized blister specimens to characterize the biaxial strength and durability of proton exchange membranes (PEMs) is proposed, simulating the biaxial stress states that are induced ...
