“…Ion exchange membranes (IEMs) are actively used in modern technologies, including water purification, concentration, electrochemical synthesis, and sensors [ 1 , 2 , 3 , 4 , 5 ]. Their use in fuel cells [ 6 , 7 , 8 , 9 ], in energy storage and conversion systems, e.g., metal-ion batteries [ 10 , 11 , 12 ], reverse electrodialysis [ 13 , 14 , 15 ], and redox batteries [ 16 , 17 , 18 , 19 ] has received the most attention in recent years. There are a number of other technologies in which ion-exchange membranes can also be used.…”

Nowadays, ion-exchange membranes have numerous applications in water desalination, electrolysis, chemistry, food, health, energy, environment and other fields. All of these applications require high selectivity of ion transfer, i.e., high membrane permselectivity. The transport properties of ion-exchange membranes are determined by their structure, composition and preparation method. For various applications, the selectivity of transfer processes can be characterized by different parameters, for example, by the transport number of counterions (permselectivity in electrodialysis) or by the ratio of ionic conductivity to the permeability of some gases (crossover in fuel cells). However, in most cases there is a correlation: the higher the flux density of the target component through the membrane, the lower the selectivity of the process. This correlation has two aspects: first, it follows from the membrane material properties, often expressed as the trade-off between membrane permeability and permselectivity; and, second, it is due to the concentration polarization phenomenon, which increases with an increase in the applied driving force. In this review, both aspects are considered. Recent research and progress in the membrane selectivity improvement, mainly including a number of approaches as crosslinking, nanoparticle doping, surface modification, and the use of special synthetic methods (e.g., synthesis of grafted membranes or membranes with a fairly rigid three-dimensional matrix) are summarized. These approaches are promising for the ion-exchange membranes synthesis for electrodialysis, alternative energy, and the valuable component extraction from natural or waste-water. Perspectives on future development in this research field are also discussed.

“…Experimental and numerical studies on high temperature PEM fuel cell (HT-PEMFC) were performed by various researchers. Polybenzimidazole (PBI) membranes are widely used due to their favorable properties such as mechanical and chemical stability, ignition resistance, high proton conductivity, moisture regainability, improved power density, higher tolerance of anode poisoning by CO, improved chemical kinetics, and enhancement of fuel cell efficiency [3]. Savadogo [4] conducted an extensive study of alternative proton conducting membranes that operate at high temperatures and compared these with low temperature perfluorinated membranes.…”

“…Generally, membranes used in HT-PEMFCs belong to four 2 of 11 groups [8]: sulfonated aromatic hydrocarbon polymer membranes [9,10], inorganic-organic composite membranes [11][12][13], membranes of blend polymers [14,15], and acid-base polymer membranes [16][17][18][19], among which phosphoric acid-doped polybenzimidazole (PA/PBI) membranes are regarded as the most promising PEMs for high-temperature operation because of features such as their high-temperature resistance, high proton conductivity, good flexibility and chemical stability, low gas permeability, and low price.

Highly phosphoric-acid (PA)-doped polybenzimidazole (PBI) membranes exhibit good proton conductivity at high temperatures; however, they suffer from reduced mechanical properties and loss of PA molecules due to the plasticity of PA and the weak interactions between PA and benzimidazoles, especially with the absorption of water. In this work, a series of PBIs with hyperbranched cross-linkers decorated with imidazolium groups (ImOPBI-x, where x is the weight ratio of the hyperbranched cross-linker) as high-temperature proton exchange membranes are designed and synthesized for the first time. We observe how the hyperbranched cross-linkers can endow the membranes with improved oxidative stability and acceptable mechanical performance, and imidazolium groups with strong basicity can stabilize the PA molecules by delocalization and hydrogen bond formation to endow the membranes with an enhanced proton conductivity and a decreased loss of PA molecules. We measured a high proton conductivity of the ImOPBI-x membranes, ranging from 0.058 to 0.089 S cm−1 at 160 °C. In addition, all the ImOPBI-x membranes displayed good mechanical and oxidative properties. At 160 °C, a fuel cell based on the ImOPBI-5 membrane showed a power density of 638 mW cm−2 and good durability under a hydrogen/oxygen atmosphere, indicating its promising use in anhydrous proton exchange membrane applications.
