Time-of-Flight Secondary Ion Mass Spectrometry for Characterization of Ir-Based Catalysts for PEM Water Electrolyzers

Abstract Iridium-based catalysts remain essential for enabling durable oxygen evolution in proton-exchange membrane water electrolyzers (PEMWEs), yet their surface and subsurface chemistries remain insufficiently resolved by conventional characterization methods. Here, we establi...
