“…At first, a homogeneous solution was formed by dissolving 0.2 g PBI and 0.1 LiCl g (PBI/LiCl: 1:0.5) in 10 mL N, N-dimethylacetamide (DMAc) under an N 2 atmosphere at 150°C. After, a suitable content of the doped-perovskite nanoparticles (2,4,6,8,10,12,14, and 16 wt.%) was dispersed by sonication for an hour. The prepared solution was cast onto a glass plate and the solvent was removed at temperatures ranging from 80°C to 120°C under vacuum condition for the duration of up to 20 hours.…”

“…In recent years, proton exchange membrane (PEM) fuel cells have concerned remarkable considerations as new technologies . In general, achievement to a high performance for PEM fuel cells needs a high proton conductivity . Application of the Nafion membrane as the most commonly used PEMs is being limited because of its high cost, low performance in temperatures above the boiling temperature of water, and so low mechanical stability at high temperatures .…”

Summary In this work, Sr2+ dopant effects of Ba0.9Sr0.1TiO3 and La0.9Sr0.1CrO3‐δ doped‐perovskite nanoparticles on increasing proton conductivity, fuel cell performance, and mechanical and thermal stability of polybenzimidazole‐based nanocomposite membranes were studied. The Sr2+ dopant creates cation vacancies in Ba0.9Sr0.1TiO3 doped‐perovskite nanoparticles and oxygen vacancies in La0.9Sr0.1CrO3‐δ doped‐perovskite nanoparticles. The oxygen vacancies, which decrease columbic repulsion between protons and positive ions, have a more important role than the cation vacancies. They provide high surface area and high interfacial interaction between La0.9Sr0.1CrO3‐δ doped‐perovskite nanoparticles, phosphoric acid, and polybenzimidazole for proton transfer and increase the proton conductivity of the nanocomposite membranes. In addition, the results of relative humidity effects showed that the ordered arrangement of oxygen vacancies of the La0.9Sr0.1CrO3‐δ doped‐perovskite nanoparticles creates a specific pathway in the nanocomposite membranes for increasing proton transfer in the presence of relative humidity. Furtheremore, at phosphoric acid doping level of 13 mol phosphoric acid per monomer unit, proton conductivity of the nanocomposite membranes containing 8 wt.% La0.9Sr0.1CrO3‐δ doped‐perovskite nanoparticles was obtained as 126 mS cm‐1 at 180°C and 6% relative humidity. The nanocomposite membrane showed the best performance and the power density of 0.62 W cm‐2 at 180°C and 0.5 V.

“…Before the test, the membranes were pretreated by immersing in 2 M H 2 SO 4 for 12 hours. The proton conductivities (σ, S cm ‐1 ) of the membranes were calculated as follows:

σ = \frac{L}{R . A},

where L (cm), A (cm 2 ), and R (Ω) are thickness, the surface area, and the bulk resistance of the membrane, respectively …”

Summary Novel blend nanocomposite proton‐exchange membranes were prepared using sulfonated poly (ether ether ketone) (SPEEK), perfluorosulfonic acid (PFSA), and Ba0.9Sr0.1TiO3 (BST) doped‐perovskite nanoparticles. The membranes were evaluated by attenuated total reflection, X‐ray diffraction spectroscopy, water uptake, proton conductivity, methanol permeability, and direct methanol fuel cell test. The effect of two additives, PFSA and BST, were investigated. Results indicated that both proton conductivity and methanol barrier of the blend nanocomposite membranes improved compared with pristine SPEEK and the as‐prepared blend membranes. The methanol permeability and the proton conductivity of the blend membrane containing 6 wt% BST obtained 3.56 × 10−7 cm2 s−1 (at 25 °C) and 0.110 S cm−1 (at 80 °C), respectively. The power density value for the optimum blend nanocomposite membrane (15 wt% PFSA and 6 wt% BST) (54.89 mW cm‐2) was higher than that of pristine SPEEK (31.34 mW cm‐2) and SPF15 blend membrane (36.12 mW cm‐2).
