A Review of Recent Developments and Advanced Applications of High-Temperature Polymer Electrolyte Membranes for PEM Fuel Cells

This review summarizes the current status, operating principles, and recent advances in high-temperature polymer electrolyte membranes (HT-PEMs), with a particular focus on developments, technical challenges, commercial prospects of HT-PEM fuel cells. A detailed most research activities has been covered by this work, major state-of-the-art concepts describing proton conductivity degradation mechanisms HT-PEMs. In addition, cell performance lifetime cells as function conditions have discussed. highlights important outcomes found literature about cell. The main objectives paper are follows: (1) latest development HT-PEMs, primarily based polybenzimidazole (2)
