The in situ study of the discharge process in a zinc‐based half‐cell employing a porous electrode as a structural scaffold is reported. The in situ characterization has been performed by synchrotron X‐ray absorption fine‐structure spectroscopy and, for this purpose, an inexpensive, simple and versatile electrochemical cell compatible with X‐ray experiments has been designed and described. The experimental results reported here have been employed to semi‐quantify the dissolved and undissolved zinc species during the discharge, allowing the cell feasibility to be tested and to better understand the functioning of the zinc half‐cell based on porous electrodes.
