Water sorption–desorption in Nafion® membranes at low temperature, probed by micro X-ray diffraction
Publikováno v:
Journal of Power Sources. 172:587-596
Using a micro X-ray beam, the structure of a water swollen Nafion® membrane, alone or in a membrane electrode assembly (MEA) designed for fuel cells, was studied upon cooling down to −70 °C. By scanning the membranes along their thicknesses, the

Structure–properties relationships in terms of gas transport have been established for a large series of sulfonated copolyimides synthesized with a naphthalenic dianhydride, a sulfonated diamine [SD] and various non-sulfonated diamines. For these t

Water vapour sorption kinetics in a H+ form naphtalenic sulfonated polyimide membrane at 25°C has been investigated by using an electronic microbalance (IGA, Hiden). An effective diffusion coefficient Dexp has been calculated from kinetic data by us

Ionomers, that is polymers containing a low concentration of charged units along the chain, have been the subject of increasing interest during the past twenty years. The presence of ionic groups in the poly mer changes some of its properties drama

A new method of water profile determination across the electrolyte of a running H 2 O 2 proton exchange membrane fuel cell (PEMFC) is described. This method, involving in situ small-angle neutron scattering (SANS) technique is based on the modificati

Acid Nafion solutions and corresponding membranes swollen by water, formamide, methanol, and ethanol were studied to assess the mobility of the perfluorinated chains in the solutions. In ethanol solutions the NMR results suggest a nearly isotropic mo
