Herein we present a design for a versatile electrochemical cell for High Energy X-ray operando studies of Membrane Electrode Assembly (MEA) based electrochemical systems. The cell flowplate materials can be interchanged according to the needs of experiments, allowing studies of different chemistries and reactions. The design also allows for coupling the X-ray elastic scattering techniques with computed tomography reconstruction, opening the possibility of 3D mapping of chemical and structural properties in operating devices. The cell has originally been designed and tested for CO2 electrolysis performance studies using Wide Angle X-ray Scattering (WAXS) technique.
