“…The doped acid makes it possible to transfer protons from the anode to the cathode. As summarized in Table 1, PA-doped PBI membrane shows decent proton conductivity, 40 mechanical properties, 41 and thermal stability 42 up to 200°C. 43 In the presence of PA, the basic amide sites of PBI-based polymer act as proton acceptors and form ion pairs.…”

Polymeric proton exchange membranes (PEMs) are vital components of fuel cells, as they enable the transport of protons while preventing the crossover of fuel and oxidant gases. However, conventional PEMs have limitations such as low use temperature, low proton conductivity, and poor mechanical and thermal stability. Various types of nanoparticles have been investigated to modify PEMs to overcome these limitations, as they can increase proton conductivity, mechanical strength, thermal stability, and chemical resistance. Metal oxides such as SiO2 and TiO2 have been shown to improve the proton conductivity and mechanical properties of PEMs. Carbon-based materials such as graphene oxide have been found to enhance both the proton conductivity and thermal stability of PEMs. The use of nanoparticles in modified polymeric PEMs for fuel cells shows excellent potential for improving the performance and durability of fuel cells. Future research should focus on developing cost-effective and scalable methods for nanoparticle synthesis and incorporation into PEMs. Polybenzimidazole (PBI) is the most widely studied high-temperature polymer for preparing composite PEMs. This review provides the recent development of PBI composite PEMs modified with different types of nanoparticles.

“…To overcome these issues, numerous sulfonated aromatic hydrocarbon polymers have been developed as alternative PEMs. These sulfonated aromatic hydrocarbon polymers include sulfonated poly (arylene ether ketone)s [17,18], sulfonated poly(benzimidazoles) [19,20,21], sulfonated poly (arylene ether sulfone)s [22,23,24], sulfonated poly(aryl ether nitrile)s [25,26,27] and sulfonated polyimides [28,29,30].…”

In order to investigate the effect of crosslinking degree on the water uptake, swelling ratio, and methanol permeability of sulfonated poly(aryl ether nitrile)s (SPENs), the molar content of sulfonated group in bisphenol monomer is fixed at 60% in this work. The properties of sulfonated poly (aryl ether nitrile) with different crosslinking degrees are studied by changing the content of propenyl group in sulfonated poly (aryl ether nitrile)s. The cross-linking reaction of the propenyl groups in the SPENs is cured at 230 °C. All the results show that this method is an effective way to improve the water uptake, swelling ratio, and methanol permeability to meet the application requirements of the SPENs membranes as proton exchange membranes in fuel cells.
