Effects of hydrothermal/thermal treatments on the water-uptake of Nafion membranes and relations with changes of conformation, counter-elastic force and tensile modulus of the matrix
TL;DR: In this paper, a kinetic investigation of the water-uptake of Nafion 117 membranes after different hydrothermal and thermal treatments was performed, and it was found that an index proportional to the counter-elastic force of the matrix can be simply derived by determining the water uptake of the samples in liquid water at 20°C.
Journal ArticleDOI
On the decay of Nafion proton conductivity at high temperature and relative humidity
TL;DR: The irreversible conductivity decay exhibited by Nafion 117 membranes above certain values of temperature and relative humidity (RH) has been investigated by two-probe impedance measurements carried out at 120°C with the electric field normal to the membrane surface, under controlled applied pressure on the electrodes as mentioned in this paper.
Journal ArticleDOI
Novel Nafion–zirconium phosphate nanocomposite membranes with enhanced stability of proton conductivity at medium temperature and high relative humidity

TL;DR: In this paper, composite membranes made of recast Nafion filled with different percentages of zirconium phosphate (ZrP) were investigated to increase the stability of conductivity at temperatures higher than 100°C.

Proton Conductivity of Composite Polyelectrolyte Membranes with Metal-Organic Frameworks for Fuel Cell Applications
Journal ArticleDOI
Mixed Membrane Matrices Based on Nafion/UiO-66/SO3H-UiO-66 Nano-MOFs: Revealing the Effect of Crystal Size, Sulfonation, and Filler Loading on the Mechanical and Conductivity Properties
Anna Donnadio,Riccardo Narducci,Mario Casciola,Fabio Marmottini,Roberto D’Amato,Mehdi Jazestani,Hossein Chiniforoshan,Ferdinando Costantino +7 more
TL;DR: The results showed that membranes containing large crystals in low amounts displayed the best results in terms of proton conductivity values, reaching values by 30% higher than those of pure Nafion, while leaving the mechanical properties substantially unchanged.
