  title = {Durable, pure water{\textendash}fed, anion-exchange membrane electrolyzers through interphase engineering},
  abstract = {<p>Anion-exchange membrane water electrolyzers (AEMWEs) promise scalable, low-cost hydrogen production but are limited by the electrochemical instability of their anode ionomers. We report interphase engineering using inorganic-containing molecular additives that coassemble with ionomer, enabling pure water{\textendash}fed AEMWEs to operate with a degradation rate \&lt;0.5 millivolt per hour at 2.0 amperes per square centimeter and 70{\textdegree}C{\textemdash}a \&gt;20-fold durability improvement. Analysis of different additives and ionomers shows that the stabilization mechanism involves cross-links between metal oxo/hydroxo oligomers and ionomers. Under operation, the inorganic additive enriches, forming an interphase near the water-oxidation catalyst that passivates the anode ionomer against continuous degradation while maintaining mechanical integrity and hydroxide conductivity. This additive-based interphase-engineering strategy provides a path to durable AEMWEs that operate without supporting electrolytes and is adaptable across diverse catalysts and ionomers for electrochemical technologies.</p>},
