چکیده
• Design of an electrochemical sensor adequate to RAMI conditions IFMIF-DONES. Determination hydrogen in liquid lithium. Online muliplex monitoring. Modular design for different extended approaches (impurities, procedures, sizes). The radiation-induced degradation materials fusion systems is planned be investigated IFMIF-DONES ( International Fusion Materials Irradiation Facility - DEMO Oriented NEutron Source ), where fast neutrons are produced by a reaction deuteron-beams with lithium target. A by-product as critical impurity hydrogen, which might affect the reliable and safe operation loops. Therefore, important issue measurement control concentrations Initially, practically applicable direct facilities did not exist. However, one promising approach manage this based on electrochemistry DONES developed Electro-Chemical Hydrogen Sensor Liquid Lithium (ECHSLL) allows electromotive Force (EMF) between reference system loop melt, thus monitoring concentrations. This article will show backgrounds non-metallic impurities metal specific material stabilities within DONES. very reactive material. Therefore issuesareviable compatibilities, interactions transport behaviour H-ions electrolytes at applied temperatures. Further issues also syntheses materials, conducting electrolytes, electrode procedures (heat treatments conditioning steps). tests showed functionality H-sensor. Beyond that, used combinations exhibited melts under harsh conditions. Hence, most aspect (stability Li-melt) has been resolved using niobium heads. observed experimental EMF potentials good accordance compared calculated models, long-time experiments.

متن کاملHydrogen storage in carbon nanotubes with Ni nanoparticles by electrochemical
In this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. Multi-Walled Carbon Nanotubes (MWCNTs) electrode was prepared by mixing with special composite. The optimum ratio of MWCNTs was estimated 30-70% (w/w) in the composite material. MWCNTs were synthesized by Chemical vapor deposition (CVD). The nanocomposite was homogenized by microwave. Cyclic voltammetry ...
