Journal of Power Sources, 2015
Abstract The past two decades have witnessed many efforts to develop radiation-grafted alkaline membranes for alkaline PEM fuel cell applications, as such membranes have certain advantages over other kinds of alkaline membranes, including well-controlled composition, functionality, and other promising properties.

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
