Novel PEFC Application for Deuterium Isotope Separation
نویسندگان
چکیده
The use of a polymer electrolyte fuel cell (PEFC) with a Nafion membrane for isotopic separation of deuterium (D) was investigated. Mass analysis at the cathode side indicated that D diffused through the membrane and participated in an isotope exchange reaction. The exchange of D with protium (H) in H₂O was facilitated by a Pt catalyst. The anodic data showed that the separation efficiency was dependent on the D concentration in the source gas, whereby the water produced during the operation of the PEFC was more enriched in D as the D concentration of the source gas was increased.

A review of research dealing with isotope hydrology in Iran and the first Iranian meteoric water line
For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...

متن کاملThe anomalous deuterium isotope effect on the chemical shift of the bridge hydrogen in the enol tautomer of 2,4-pentanedione.
The nature of the intramolecular hydrogen bond in the enol tautomer of 2,4-pentanedione has been investigated by high resolution proton and deuteron magnetic resonance spectroscopy. An unusually large deuterium isotope effect on the chemical shift of the bridge hydrogen has been observed. This unexpected result, together with the observation of a pronounced temperature dependence for both the p...
متن کاملQuantum effect induced reverse kinetic molecular sieving in microporous materials.
We report kinetic molecular sieving of hydrogen and deuterium in zeolite rho at low temperatures, using atomistic molecular dynamics simulations incorporating quantum effects via the Feynman-Hibbs approach. We find that diffusivities of confined molecules decrease when quantum effects are considered, in contrast with bulk fluids which show an increase. Indeed, at low temperatures, a reverse kin...
