Constructing a Highly Cross-Linked Hydrogen Network by Integrating Poly(4,4′-diphenylether-5,5′-benzimidazole) with Phosphoric Acid-Modified COFs

Key Points

• To investigate the construction of a highly cross-linked hydrogen network to improve fuel cell performance.
• Integrated poly(4,4′-diphenylether-5,5′-benzimidazole) with phosphoric acid-modified COFs.
• Assessed fuel cell performance under cycling conditions from room temperature to 160 °C.
• Fuel cell with 12%Tp/PA@OPBI maintained 88% performance after 30 cycles.
• Demonstrated effective thermal stability under high-temperature conditions.
