Hydrogen bonding assisted OH- transport under low humidity for rapid start-up in AEMFCs

Wanjie Song et al.

Summary: This study reports an AEM with a urea-based structure that exhibits excellent performance under low humidity conditions. Micro-structure analysis and molecular dynamics simulation show that hydrogen bonding between urea-based structures enhances the self-assembly ability and OH- conduction pathway of the AEM. The hydrogen bond network formed by urea-urea and urea-water groups endows the AEM with excellent water retention ability, reducing the dependence of OH- conduction on humidity. The research provides significant guidance for rapid start-up in AEM fuel cells.
