Om. Ivanchuk et al., Isotopic effects of hydrogen during the decomposition of water in electrolysis with a solid polymer electrolyte, ATOM ENERGY, 89(3), 2000, pp. 745-749
The partition coefficients of hydrogen isotopes in the decomposition of wat
er in electrolyzers with a solid polymer electrolyte are measured in a wide
range of deuterium content in the initial water (from the natural content
up to close to 100%), including for water containing trace concentrations o
f tritium. Equations describing the temperature dependence of the partition
coefficients (temperature range 298-333 K) and the deuterium content depen
dence of the tritium partition coefficient are obtained. Partition coeffici
ents are presented for binary isotopic mixtures protium-deuterium, protium-
tritium, deuterium-tritium. 1 figure, 3 tables, 17 references.
