Here we report novel poly(arylimidazolium) membranes (QAI\u2010x) that overcome this barrier through an aryl\u2010tethered pendant sterically shielded imidazolium cation. This architecture sterically protects the imidazolium cation while avoiding the introduction of a benzylic cation\u2013polymer linkage. Combined with ether\u2010free polyaromatic backbones, the QAI\u2010x membranes simultaneously achieve enhanced chemical stability and dimensional stability, with no measurable loss in hydroxide conductivity after 4000\u00a0h in 1\u00a0M KOH at 80\u00b0C, resistance to Fenton oxidation, and limited dimensional swelling despite relatively high water uptake. In AEMWEs, QAI\u2010x membranes support voltage decay rates as low as 9 \u00b5V h\n                    <jats:sup>\u22121<\/jats:sup>\n                    over 5400\u00a0h in 1\u00a0M KOH and 16 \u00b5V h\n                    <jats:sup>\u22121<\/jats:sup>\n                    over 2000\u00a0h in 5\u00a0M KOH at 80\u00b0C and 2.5\u00a0V, substantially outperforming commercial benchmarks.
