Dual-Bond-Reinforced 3D Network Membrane with Nitrogen-Ratched Ionic Polymer for Enhanced Durability and High-Power HT-PEMFCs.
Polybenzimidazole (PBI) membranes doped with phosphoric acid (PA) are promising electrolytes for high-temperature proton exchange membrane fuel cells (HT-PEMFCs) due to their excellent thermal stability and intrinsic mechanical strength. However, their practical performance is often constrained by insufficient PA uptak...
