Preparation and molecular simulation of grafted polybenzimidazoles containing benzimidazole type side pendant as high-temperature proton exchange membranes

Yiming Xiao et al.

Summary: Phosphoric acid-doped polybenzimidazole membranes with side chains of benzimidazole group exhibit excellent properties in terms of doping level of phosphoric acid, retention stability of phosphoric acid, and proton conductivity under certain mechanical properties, oxidation resistance, and thermal stability. The performance of the grafted membrane is mainly improved by increasing the free volume of the polymer membrane, enhancing the binding energy, and densifying the hydrogen bond network structure between the polymer membrane and phosphoric acid. Adjusting the length of the side chain and the number of benzimidazole groups allows for precise control of phosphoric acid retention stability and proton conductivity.

Simultaneous hydrogen and oxygen permeation through BaCe0.70Fe0.10Sc0.20O3-δ perovskite hollow fibe0r membranes

Jian Song et al.

Summary: A BCFS perovskite hollow fiber membrane was prepared by phase inversion and sintering technique with the addition of Co2O3 to enhance mechanical strength and reduce sintering temperature. The membrane exhibits simultaneous permeation of hydrogen and oxygen, showing potential as a catalytic membrane reactor for various reactions. Simultaneous permeation enhances hydrogen and oxygen fluxes by reducing gas concentrations and promoting gas/ion exchange reactions.

Constructing stable continuous proton transport channels by in-situ preparation of covalent triazine-based frameworks in phosphoric acid-doped polybenzimidazole for high-temperature proton exchange membranes

Jinwu Peng et al.

Summary: In this research, a stable proton transport channel was constructed for the first time through in-situ preparing CTFs in PBI under mild TFA catalysis. Membranes containing 30% CTFs showed the best performance, with high conductivity, low volume swelling, and high PA retention ability. The study demonstrates that constructing a stable proton transport channel can significantly improve the properties of HTPEMs.

Fabrication of PBI/SPOSS hybrid high-temperature proton exchange membranes using SPAEK as compatibilizer

Jiayu Yang et al.

Summary: Exploring new methods for developing high-performance membrane materials for use in high-temperature proton exchange membrane fuel cells is important due to the harsh operating conditions. In this study, a new family of hybrid membranes was successfully obtained through the incorporation of sulfonated poly (aryl ether ketone) (SPAEK) compatibilizer and polyhedral-oligosilsesquioxane nanoparticles bearing sulfuric acid groups (SPOSS) into a soluble arylether-type polybenzimidazole (Ph-PBI) matrix. These hybrid membranes exhibited enhanced acid absorption, doping levels, acid retention, and mechanical-dimensional stability, with a high proton conductivity of 126 mS cm(-1) at 200 degrees C. They were also suitable for membrane electrode assemblies (MEAs) and achieved a maximum power density of 300 mW cm(-2) at 160 degrees C without humidity.
