“…Recently, Nafion/Fe 2 TiO 5 nanocomposite membranes were prepared by dispersion of Fe 2 TiO 5 nanoparticles within the commercial Nafion membranes [23]. Incorporation of Fe 2 TiO 5 nanoparticles in Nafion matrix improved the thermal stability of Nafion membranes, which is important for operation of PEMFCs at elevated temperatures.…”

In this work, Fe 2 TiO 5 nanoparticles were used for improving the proton conductivity, and water and acid uptake of polybenzimidazole (PBI)-based proton exchange membranes. The nanocomposite membranes have been prepared using different amounts of Fe 2 TiO 5 nanoparticles and dispersed into a PBI membrane with the solution-casting method. The prepared membranes were then physico-chemically and electrochemically characterized for use as electrolytes in hightemperature PEMFCs. The PBI/Fe 2 TiO 5 membranes (PFT) showed a higher acid uptake and proton conductivity compared with the pure PBI membranes. The highest acid uptake (156 %) and proton conductivity (78 mS/cm at 180°C) were observed for the PBI nanocomposite membranes containing 4 wt% of Fe 2 TiO 5 nanoparticles (PFT 4 ). The PFT 4 composite membrane showed 380 mW/cm 2 power density and 760 mA/ cm 2 current density in 0.5 V at 180°C at dry condition. The above results indicated that the PFT 4 nanocomposite membranes could be utilized as proton exchange membranes for high-temperature fuel cells.

“…It was found that the composite membranes have a higher water retention and thermal stability than that of Nafion 117, perhaps because of responsibility of both acidic groups and nanoporous structure of silica additive. Nafion/Fe 2 TiO 5 nanocomposite membranes for proton exchange membrane fuel cells (PEMFCs) were investigated and showed a higher water uptake, proton conductivity and thermal stability compared with the pure commercial Nafion membranes [17].…”

Organic-inorganic nanocomposite membranes of poly(vinyl alcohol) (PVA) and nanoporous silica containing sulfonic acid groups are synthesized in order to increase the proton conductivity, water retention and thermal stability of membrane. The cross-linked PVA/ SBA-15-propyl-SO 3 H nanocomposite membrane was prepared by solution casting method. Infrared spectroscopy and scanning electron microscopy are used to characterize and confirm the structure of PVA and the cross-linked membranes. The impedance spectroscopy, water uptake and thermal stability of membranes are investigated to confirm their applicability in fuel cells. It was found that the cross-linked PVA/SBA-15-propyl-SO 3 H nanocomposite membrane appears to be a good candidate for using in PEM fuel cell.

“…This improvement was attributed to the hygroscopic nature of BaZrO3 and SrCeO3 nanoparticles. Also they investigated the effects of variations in the percentages of the nanoparticles and the solvent used (water, ethanol, and water/ethanol (1:1 v/v)) for the dispersion of nanoparticles within of Nafion ® /Fe2TiO5 nanocomposite membranes on the proton conductivity, water uptake, and also the thermal stability of the membranes (Hooshyari et al, 2014). The results displayed that 2 wt.% of the nanoparticles vs. Nafion ® membrane in 10 mL water as solvent had the highest proton conductivity (226 ± 7 mS cm -1 ) compared with the other membranes at 25 ºC and 95% RH due to the existence of water as more polar solvent and large affinity of the Fe2TiO5 nanoparticles with water.…”
