Determination of tritium enrichment parameters of a commercially available PEM electrolyzer: a comparison with conventional enrichment electrolysis

Monolayer Hexagonal Boron Nitride Nanosheets as Proton-Conductive Gas Barriers for Polymer Electrolyte Membrane Water Electrolysis

“…With the growing demand for renewable and carbon-free energy sources, water electrolysis has been increasingly studied as a clean technology to produce hydrogen, which can be used as an energy carrier . Furthermore, water electrolysis has been regarded as an efficient method for the enrichment or removal of hydrogen isotopes (i.e., deuterium and tritium) based on the preferential dissociation of protons from water by electrolysis; this preferential dissociation is ascribed to the lower dissociation energy of lighter molecules compared to heavier molecules. , Various types of water electrolysis technologies, including alkaline water electrolysis, solid oxide water electrolysis, and proton exchange membrane (PEM) water electrolysis, have been suggested. , Among the various water electrolysis technologies, PEM water electrolysis has been considered a promising electrolysis method because of its many advantages, including higher hydrogen purity, higher energy efficiency, and the capability of operating at higher pressures compared to other technologies. − …”
