Polybenzimidazole synthesis process.

• Polybenzimidazole synthesis process 25 g of BOPBI and different proportions of IL were dissolved in DMSO, when they were dispersed in the vials, 2,2-azobisisobutyronitrile with a quality percentage of ionic liquid and KH-560 with a weight ratio of 3% were added to the homogeneous solution, and after 15–20 min, the stages which is discussed below. The performance, limitations, and possibilities for the practical implementation of different high-temperature PEMs utilized in fuel cells are discussed in this review paper.
