“…In recent years, perovskite nanoparticles have been received great attention for use in PEMFCs because of their improved chemical, mechanical, and thermal stability 26 . The proton transfer in perovskite nanoparticles is due to hydrogen bonds created between their neighboring lattice oxygen which this bonding facilitates the proton conductivity of the prepared PEM.…”

In this study, new nanocomposite membranes from sulfonated poly (ether ether ketone) (SPEEK) and proton-conducting Fe2TiO5 nanoparticles are prepared by the solution casting method. Sulfonated core–shell Fe2TiO5 nanoparticles are synthesized by redox polymerization. Therefore, 4-Vinyl benzene sulfonate (VBS) and 2-acrylamide-2-methyl-1-propane sulfonic acid (AMPS) are grafted on the surface of nanoparticles through radical polymerization. The different amounts of hybrid nanoparticles (PAMPS@Fe2TiO5 and PVBS@Fe2TiO5) are incorporated into the SPEEK matrix. The results show higher proton conductivity for all prepared nanocomposites than that of the SPEEK membrane. Embedding the sulfonated Fe2TiO5 nanoparticles into the SPEEK membrane improves proton conductivity by creating the new proton conducting sites. Besides, the nanocomposite membranes showed improved mechanical and dimensional stability in comparison with that of the SPEEK membrane. Also, the membranes including 2 wt% of PAMPS@Fe2TiO5 and PVBS@Fe2TiO5 nanoparticles indicate the maximum power density of 247 mW cm−2 and 226 mW cm−2 at 80 °C, respectively, which is higher than that of for the pristine membrane. Our prepared membranes have the potential for application in polymer electrolyte fuel cells.

“…Just 2.6% of the entire proton conductivity of PA-PBI-based HT-PEMs is controlled with the 'vehicular' mechanism [129]. The proton conductivity of PA-PBI-based HT-PEMs is increased by an increase in relative humidity [130]. A rise in RH can increase the molecular interaction between free PA sites (amino groups of PBI and water in PA-PBI-based HT-PEMs).…”

“…The sulfonated PBI (sPBI)/sulfonated imidized graphene oxide (SIGO) is another potential candidate for developing HT-PEM fuel cells that have been mainly proposed in order to solve the disadvantages associated with sPBI polymers such as low proton conductivity, poor water uptake, and ion exchange capacity [130]. Imran et al [168] incorporated multifunctionalised covalently bonded SIGO into the sPBI matrix synthesized by direct polycondensation in PA for the application in PEMs.…”

“…The mechanical properties and proton conductivity of the PBI-based membranes could be enhanced by various methods such as thermal crosslinking of PBI [150], crosslinking with phenylsulfonated TiO 2 (as both the filler and the crosslinking agent) [126], and the formation of a highly acidophilic imidazolerich crosslinking network [49,171]. There have been studies of different membranes based on strong proton conductors such as ferric sulfophenyl phosphate (FeSPP) [172], cerium sulfophenyl phosphate (CeSPP) [130], zirconium sulfophenyl phosphate (ZrSPP), and PBI [172]. Incorporating FeSPP in the PBI matrix as an insoluble proton conductor not only could provide a robust high-temperature proton conductivity but also improve the dimensional stability and the oxidative resistance of the resulting membrane.…”

“…4 In the past few decades, countless researchers have been developing low-cost and high-performance PEMs. Their works mainly includes some sulfonated aromatic polymers, such as sulfonated poly(aryl ether ketone), 5 –7 sulfonated poly(aryl ether sulfone), 8 –13 sulfonated polyimide 14 –17 and sulfonated polybenzimidazole. 18 –22 Most of these sulfonated polymers have proton conductivity comparable to Nafion membrane only at high degree of sulfonation (DS).…”

A sulfonated poly(aryl ether ketone sulfone) (SPAEKS) with locally dense sulfonic acid groups is synthesized and different amounts of TiO2 is doped into SPAEKS matrix to prepare composite membranes (SPAEKS/TiO2-x). SEM shows that TiO2 in the composite membranes has good dispersibility when TiO2 content is not higher than 3%. The composite membranes show good mechanical properties, dimensional stability and oxidative stability. The proton conductivity of composite membranes is near to that of Nafion 117 membrane and methanol permeability of composite membranes is much lower than that of Nafion 117 membrane. Therefore, the proton selectivity of composite membranes is higher than that of Nafion 117 membrane. In particular, proton selectivity of SPAEKS/TiO2-3% (12.8 × 104 S s cm−3) is four times higher than that of Nafion 117 membrane (3.2 × 104 S s cm−3).
