Effects of electrochemical hydrogen charging on electrical properties of WO3 ceramics
Journal of Materials Science, 2007Tungsten trioxide (WO3) films are used extensively in eletrochromic devices [1], surface acoustic wave gas sensors [2] and photo-catalytic degradation [3]. In recent years, there has also been a growing interest in WO3-based ceramics. Due to their high dielectric constant, WO3 ceramics have been proposed for applications in ceramic capacitors [4].

AbstractDecoupled hydrogen and oxygen production were successfully embedded into an aqueous dual‐electrolyte (acid–base) battery for simultaneous energy storage and conversion. A three‐electrode configuration was adopted, involving an electrocatalytic hydrogen‐evolving electrode as cathode, an alkaline battery‐type or capacitor‐type anode as shuttle ...

Water‐Induced Degradation of Barium Titanate Ceramics Studied by Electrochemical Hydrogen Charging
Journal of the American Ceramic Society, 2003Water‐induced degradation of barium titanate (BTO) ceramics has been investigated using electrochemical hydrogen charging, in which the silver electrodes of BTO ceramic specimens are made cathodes in a 0.01 M NaOH solution to evolve hydrogen by electrolysis of water.

Hydrogen Degradation Property of Electrochemically Charged Aluminum
MRS Proceedings, 2007AbstractDegradation property of aluminum due to hydrogen is studied. Hydrogen is introduced by electrolysis charge in aqueous solution with addition of 0.1 mass % NH4SCN as a hydrogen recombination poison. The amount of hydrogen and its existing state in the material is analyzed by hydrogen desorption curves measured by the thermal desorption ...

Positron Annihilation in Copper Hydrogen-Charged Electrochemically
Russian Journal of Electrochemistry, 2004Atomic–electronic structure of copper foils is studied by a positron annihilation method directly in the course of electrochemical hydrogen sorption and after switching the current off. The shape of the curve of angular correlation of the annihilation radiation (ACAR) alters: the intensity of the broad Gaussian component, which is connected with the ...

Electrochemical Hydrogen Charge Characteristics of Metal Hydride Electrodes
Berichte der Bunsengesellschaft für physikalische Chemie, 1992AbstractA model for the cathode potential vs. time relationship during the galvanostatic charge process for metal hydride electrodes has been derived on the basis that the adsorbed hydrogen produced at the electrode surface by charge transfer of the Volmer reaction diffuses through the bulk electrodes, i.e., α, (α+β) and β phases during the charge ...

Researches on Fracture Surfaces Electrochemically Charged with Hydrogen
Advanced Materials Research, 2014The present paper deals with the morphological alteration of fracture surfaces determined by hydrogen in the case of hydrogen based steels, through electrochemical methods as compared with similar samples of surfaces electrochemically uncharged or with welding deposits created by means of cellulose coated electrodes.
