    摘要： The invention relates to isotope separation methods, and methods for separating isotopes with low energy consumption, demonstrated using hydrogen isotopes. To this end, an isotope transfer electrochemical cell is provided, which comprises an anode plate and a cathode plate; current carrier plates with flow channels or mesh layers or porous material; a proton exchange membrane or solid polymer electrolyte membrane; and gas diffusion layers positioned on either side of the proton exchange membrane which together with the proton exchange membrane forms a membrane electrode assembly; and a housing containing the anode and cathode plates in operable arrangement with the membrane electrode assembly, and defining a hydrogen feed inlet on the anode, a product outlet on the cathode, an outlet for excess hydrogen on the anode, and internal flow paths for transfer of gases and fluids on either side of the membrane electrode assembly. Also described are methods for enriching or depleting the isotope present in the hydrogen gas/vapour feed e.g. for tritium removal, tritium enrichment and deuterium enrichment, by arranging a series of cells in a cascaded configuration.

    摘要： A flowcell 2 is constituted of insulating substrates 2a and 2b. The two substrates 2a and 2b have been directly bonded to each other by a bonding method for attaining tenacious bonding, for example, anodic bonding or hydrofluoric acid bonding. A channel 6 has been formed at the interface between the substrates 2a and 2b. Part of the substrate 2a which faces the channel 6 has a carbon electrode 4a formed thereon by sintering a pasty carbon material, the electrode 4a extending along the channel 6. On the other hand, the substrate 2b has a groove 6a serving as the channel 6, and has an electrode 4b made of a metal film formed on a bottom surface of the groove 6a.
