We present the design of a modular multipurpose cell for monitoring the degradation of materials in extreme environments. This cell decouples the reference electrode from the working and counter electrodes, permitting precise electrochemical control and measurement reliability. The design is compatible with fourth generation synchrotron light sources, and its emphasis on modularity facilitates adaptation to different beamlines, where there may be variations in sample stage requirements and X-ray imaging techniques. Experimental tests with the novel design demonstrate its support of real-time corrosion and hydrogen embrittlement measurements under Bragg Coherent Diffraction Imaging (BCDI) configurations.
