Application and Research of Proton Conductors in the Fuel Cycle of Nuclear Fusion

The electrochemical hydrogen pump (HP) with a proton conductor as the main component can extract hydrogen from hydrogen-helium mixture gas containing 1000ppm or 10ppm hydrogen. It was found that a characteristic voltage (1.02V and 1.51V respectively) could be measured in atmospheres without concentration difference of Coolant Purification System (CPS) and Tritium Extraction System (TES), and the electrical parameters of HP were linear when applying an applied signal below the characteristic voltage and nonlinear when applying an applied signal above the characteristic voltage. This function can be applied to achieve fuel cycle recovery in nuclear fusion.
