Here, a series of partially PEG\u2010grafted poly(terphenyl piperidinium) with different side chain length are synthesized using simple postpolymerization modification to produce AEMs with balanced properties. The polar and flexible PEG side chains are responsible for the controlled water uptake and swelling, superior hydroxide conductivity (122 mS cm<jats:sup>\u22121<\/jats:sup> at 80 \u00b0C with an IEC of 1.99\u00a0mmol g<jats:sup>\u22121<\/jats:sup>), and enhanced alkaline stability compared to the reference sample without PEG grafts (PTP). More importantly, the performance of AEM fuel cell (AEMFC) with the membrane containing partial PEG side chains surpasses that with PTP membrane, demonstrating a highest peak power density of 1110\u00a0mW cm<jats:sup>\u22122<\/jats:sup> at 80 \u00b0C under optimized conditions. This work provides a novel approach to the fabrication of high\u2010performance AEM materials with balanced properties for alkaline fuel cell
