Abstract:The stability of catalyst layers and membranes in proton exchange membrane water electrolysis (PEMWE) cells represents an ongoing challenge, compounded by the dissolution of components and migration of elements within the catalyst‐coated membrane (CCM). Conventional microscopy methods often struggle to efficiently evaluate large cross‐sections of PEMWE membranes, which is essential for representative analysis of technical scale CCMs. Herein, synchrotron radiation‐based X‐Ray fluorescence microscopy is exploite… Show more
