In order to have a better understanding of nafion behaviour in fuel cells operating at temperatures higher than 80 oC,…
The possibility of increasing the working temperature of fuel cells using Nafion as ionomer membranes by a new annealing procedure…
This review describes main strategies for the development of sulfonated aromatic polymers (SAP) with optimal properties for medium temperature (90–120…
The proton conductivity of SPEEK membranes in situ cross-linked by thermal treatment at 180 °C for various times was investigated by impedance spectroscopy. The conductivity measurements…
SPEEK has been widely considered as a promising alternative to Nafion® membrane for PEMFC. However, a conflict between high degree of…
In this work, electropolymerization of sulfonated phenol were performed by cyclic voltammetry (CV) on planar or nano‐architecture substrates. The corresponding…
Highly sulfonated polyethersulfone (SPES; Ione exchange capacity = 3.2 meq/g) and polyphenylsulfone (SPPSU; ion exchange capacity = 3.2 meq/g) were synthesized. To get high thermal and…
Sulfonated PolyEtherEtherKetone (SPEEK) was thermally treated at 180 and 140 °C to study the effects of polymer cross‐linking and annealing on…
The cross‐link reaction between macromolecular chains of sulfonated poly(ether ether ketone) (SPEEK) by thermal treatment above 150 °C in presence of…
