The electrochem. behavior of synthetic B-doped diamond thin-film electrode (BDD) was studied in acid media contg. 4-chlorophenol (4-CP) by cyclic voltammetry, chronoamperometry, and bulk electrolysis. The results showed that in the potential region of supp ...
A preliminary study was made of the cathodic properties (redn. of Ce(IV) and hydrogen evolution) of ZrO2 layer formed on Zr by thermal decompn. at high temp. Zr was chosen as base metal due to the fact that this valve metal is stable under conditions of hy ...
The performance of the electrolytic ozone generation using a solid polymer electrolyte (SPE) and Pb anode is described. This anode has been prepd. by application of Pb powder on a porous Ti substrate coated with IrO2 layer (Ti/IrO2/Pb anode). Electrochem. ...
oarse 8YSZ powders destined for plasma spray deposition were obtained from three different suppliers (Hochrhein, Magnesium Elektron, Unitec). Their ionic conductivities were measured by impedance spectroscopy on pellets prepared by vacuum hot pressing. Den ...
Electrolysis cell with a bipolar electrode is described. The bipolar electrode in this electrolytic cell comprises a substrate coated with doped diamond electroconductive film. [on SciFinder (R)] ...

Ni-YSZ anode supports show a fundamentally different microstructure from screenprinted Ni-YSZ anodes on YSZ electrolyte supports. Of high density and composed of fine zirconia and nickel oxide to allow for cofiring with a thin zirconia electrolyte film (5 ...
Ceria-zirconia-ceria sandwich structured composite filmelectrolytes were designed in order to offer high ionic and low electronicconductivity electrolyte films. Calculation of oxygen potential profile inthe composite film electrolyte indicates that a very ...
A thin aqueous layer is formed between the polymeric ion-selective membrane and an inner gold electrode. Its composition can be altered upon sample changes, which leads to drifting potentials. It is shown by theory and experiment that interfering ions ente ...
A general procedure based on the oxalate coprecipitation route was developed to produce very sinterable ceria (CeO2) powder doped with Gd2O3, Sm2O3 or Y2O3. The method is simple, reliable and very reproducible. Without any milling step, powder of 20 mol% G ...
A bipolar filter press-type elec. rechargeable Zn/O2 battery has been developed. Reticulated copper foam served as substrate for the zinc deposit on the anodic side, and La0.6Ca0.4CoO3-catalyzed bifunctional oxygen electrodes were used on the cathodic side ...
