Abstract A novel alkaline anion exchange membrane was designed using poly(styrene‐b‐ethylene‐co‐butylene‐b‐styrene) (SEBS) as the backbone. Long side chains were grafted onto SEBS via a Friedel‐Crafts reaction, and cross‐linked (SEBS‐C6‐DiPRD) prepared an N‐heterocyclic crosslinker, 1,3‐N‐4‐piperidinyl propane, which features ring strain steric hindrance. The SEBS‐C6‐DiPRD exhibited ion capacity of approximately 1.8 mmol·g −1 , water uptake 85.4%, swelling ratio 24.1% at 80 °C. Thermal degradation began 370 °C, broke 310.6% stress 31.1 MPa. At operating temperature °C (typical for AEMFCs), conductivity reached 75.95 mS·cm . Notably, after 1000 hours testing under simulated AEMFC conditions, membrane's only decreased by 27.6%, demonstrating excellent long‐term stability. Under H 2 air peak power density 18.89 mW·cm −2

Abstract Anion exchange membrane fuel cells (AEMFCs), which operate in alkaline environments, offer advantages such as compatibility with non‐precious metal catalysts Fe‒N‒C, making them an alternative to Pt‐based systems. This study explores development of iron phthalocyanine (FePc)‐derived Fe‒N‒C for AEMFCs, focusing on optimizing oxygen reduction reaction (ORR) activity and durability. The Fe‒N‒C/C were synthesized by pyrolyzing FePc supported carbon (FePc/C) precursors at varying temperatures (500°C–900°C), followed acid washing. High‐angle angular dark field scanning electron microscopy confirmed the atomic dispersion Fe species, while X‐ray photoelectron spectroscopy analysis revealed impact pyrolysis temperature active site configuration. catalyst heat treated 600°C exhibited optimal balance content pyrrolic‐N, resulting superior ORR performance a half‐wave potential ( E 1/2 ) 0.882 V, surpassing commercial Pt/C. Durability tests demonstrated minimal losses (3 mV after 20 000 cycles, emphasizing strong coordination Fe‒N x sites matrix. In single‐cell tests, promising comparable that Pt/C high‐operating voltage region. These findings highlight cost‐effective, durable AEMFCs.
