摘要
Modern anion exchange membrane (AEM) fuel cells (AEMFCs) call for highly conductive, durable, and mechanically tough AEMs and ionomers. Here, we report a series of scalable di-piperidinium-crosslinked poly(fluorenyl-co-terphenyl piperidinium) (x-PFTP-DP-Cn) copolymers with high ion exchange capacity (IEC) and tunable crosslinking alkyl spacers (Cn, n = 5 or 10) to reinforce the mechanical strength and optimize the electrochemical performance of poly(aryl piperidinium)-based AEMFCs. Specifically, durable x-PFTP-DP AEMs display high ion conductivity (HCO3- >90 mS cm(-1) and OH- >180 mS cm(-1) at 90 degrees C) and excellent mechanical strength (tensile strength similar to 90 MPa, elongation at break similar to 35%). Importantly, the x-PFTP-DP-based AEMFCs achieve outstanding peak power densities of 2.50 W cm(-2) in H-2-O-2 and similar to 1.41 W cm(-2) in H-2-air at 80 degrees C. Moreover, the present AEMFCs can run stably under 0.2 A cm(-2) and 0.6 A cm(-2) current densities at 70 degrees C for 265 h and 110 h, respectively, with low voltage decay rate of similar to 50 mu V h(-1).
