Degradation of polymer electrolyte membranes
International Journal of Hydrogen Energy, 2006One of the predominant failure modes of polymer electrolyte membrane (PEM) fuel cells is the degradation of the PEM, especially when the fuel cell is used for transportation applications. Numerous studies have been carried out regarding this issue but many aspects of the degradation are not yet understood.

Composite Solid Polymer Electrolyte Membrane
ECS Meeting Abstracts, 2016Due to safety issues in the lithium batteries with organic liquid electrolytes, it is expected that the next-generation safe lithium batteries would be the all-solid-state batteries. New solid electrolytes with high Li+ ion conduction such as Li10GeP2S12, Li1.3Al0.3Ti1.7(PO4)3 and Li7La3Zr2O12 have attracted extensive attentions in the development of

Perfluorinated Polymer Electrolyte Membrane Durability
Journal of Macromolecular Science, Part C: Polymer Reviews, 2006Durability is a critical issue in all fuel cell systems, certainly so for PEM membrane polymers. Perfluorinated ionomers are generally favored in PEM systems at the present time; the useful lifetimes of such systems can be limited by damage including membrane thinning, weight loss, and redistribution of catalyst materials during fuel cell operation ...

Modeling of Polymer Electrolyte Membrane Fuel Cells
2023This chapter outlines analytical and numerical methods for modeling proton exchange membrane fuel cells. To provide the fundamentals of fuel cell simulation, a monodimensional analytical (steady-state isothermal) model for reconstructing the cell polarization curve is presented and then applied to a case of practical interest. The monodimensional model

Degradation of Polymer Electrolyte Membranes
Premature failure of polymer electrolyte membranes used in proton exchange membrane fuel cells result in short life and degradation of performance of the fuel cell stack. Changes in the humidity and temperature cause swelling and shrinking of the membrane which result is stresses in the membrane. Stress relaxation and changes in conductivity will occurAlan Jones, Jaya Malladi
