Experimental data for a solid polymer electrolysis system for tritium enrichment using a gold catalyst

This dataset contains the experimental data supporting the manuscript entitled “Solid polymer electrolysis system for tritium enrichment using gold catalyst.” It includes D/H separation factors obtained using different cathode catalysts; D/H and T/H separation factors measured with an Au/C cathode at 25 A; water-temperature, D/H separation-factor, and polarization data acquired at different currents; initial and final volumes, tritium and deuterium concentrations, enrichment factors, recovery factors, cell constants, and dead volumes from six tritium-enrichment experiments; and data concerning dead-volume correction, memory-effect removal, and reproducibility tests.

The dataset supports Figs. 2–8 and Tables 1 and 3 of the manuscript. The data are provided in opju and XLSX formats with a data dictionary and usage documentation.
