This proposed effort aims to develop and demonstrate the cell architectures and tools necessary to study electrocatalytically active interfaces under ‘real’ electrolyzer conditions. These tools will enable us to execute advanced operando x-ray techniques for microscopy and spectroscopy at the Stanford Synchrotron Radiation Lightsource (SSRL), and we will use these techniques to deepen our understanding of how the different components of the MEA operate as a system, gaining insights into the factors that govern efficiency and durability under relevant operating environments.

The methods developed in this project will provide researchers with new tools and capabilities to address gaps in translating knowledge from fundamental studies to applied systems and pave the path to achieve new insights into high-performance water electrolyzers.
