Hydrogen Gas Diffusion Electrode in Dilute Sulphuric Acid Solutionus conditions. These current densities were obtained using mixtures of hydrogen and inert gases..To elucidate the dependence of the overal mass transport coefficient, a simplified model to describe the transport of hydrogen in a GDE based on literature models was derived. The GDE consists of a hydro

Combined Electrochemical and Dilatometry Studies on Metal Hydridesischarged electrochemically with hydrogen under constant current conditions. Electrode length changes were measured under normal atmospheric pressure at different charging rates and as a function of hydrogen content. Structural changes were followed by SEM observations. The results are compared to t

Galvanic Deposition of Photovoltaic Compound Semiconductor Coatingsussed. As typical examples fit for the galvanic formation of semiconducting coatings Cu(I) sulfide and Cu(I) selenide have been investigated. The anodic formation of copper (I) sulfide layers composed of relatively large twinned crystals by anodic oxidation of copper in electrolytes containing sulfi

Energy Correlation of Mass Transfer in Decaying Annular Swirl Flow limiting diffusion current technique. Swirl was generated using axial guide-vanes with vane angles between 15–67° to the duct axis. Pressure measurements at the outer wall were also made to enable estimation of the energy cost of mass transfer enhancement. Overall correlation of mass transfer at th

Modelling the Phenomena Associated with the Application of Centrifugal Fields in Fused Salt Electroluch that current efficiencies as high as 93 % were attained using electrode spacings of a few millimetres and rotation speeds of 100 rpm..To assess the feasibility of the technique applied to light metal electrowinning, a low temperature hydrodynamic model was constructed. Almost complete separation

The Anodic Oxidation of Vanadium — a Possible Technical Application of Electrochemical Fixed Bed Rearavalent form. An electrochemical reoxidation could be an alternative to the conventional oxidation by air. Based upon experimental studies and calculations, with the help of a mathematical fixed bed reactor model, a process quantification was carried out for a given oxidation capacity. Parametric s

Electrosynthesis of Aqueous Ti3+ SolutionsTi(IV) reduction mechanism was operative in HCl, Ti(IV) reduction in H.SO. appeared to involve a Ti(IV)-Ti(III) intermediate, which absorbed visible light strongly, and proceeded via an ECE mechanism. A potentiostatically controlled amalgamated lead plate cathode was used to reduce Ti(IV) species in
