On the impedance of galvanic cells
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1967Summary A critical discussion is presented of some important theories for the electrode impedance in the case that the electroactive species are specifically adsorbed at the electrode-solution interface. It is argued that the equations given by Reinmuth are the most satisfactory so far available for reversible systems.

A nanometer-scale galvanic cell
The Journal of Physical Chemistry, 1992An electrochemicaI cell having a largest total dimension of 70 nm was assembled on the surface of a highly oriented pyrolytic graphite crystal by electrochemically depositing copper and silver pillars (diameter ≃150-200 A) in close proximity to one another using the scanning tunneling microscope (STM).

A galvanic cell oxygen analyzer
Journal of Electroanalytical Chemistry (1959), 1962Abstract A galvanic cell consisting of a silver-lead couple separated from the test sample by an oxygen permeable plastic membrane provides the basis of a simple oxygen analyzer. The current generated, while directly proportional to the amount of oxygen in the sample, also depends upon factors such as temperature, membrane thickness, kind and ...

Galvanic cells including cobalt-chromium alloys
Acta Odontologica Scandinavica, 1980Galvanic cells may be created when dentures made of cobalt-chromium alloys are placed on teeth with metallic restorations. The power of such cells was evaluated in an in vitro galvanic using amalgams, gold alloy, and nickel-chromium alloys. The amalgams and one of the nickel-chromium alloys revealed high corrosion currents when placed in contact with ...

Two dissimilar metals, A and C, subject to corrosion in the same electrolyte, normally are at different corrosion potentials, (ea)corr and (ec)corr. The electrode system metal C/solution/metal A then is a galvanic cell with the open-circuit voltage $$ \Delta \varepsilon = (\varepsilon _c )_{corr} - (\varepsilon _a )_{corr} $$ (11.1) We choose

Redox Potentials and Galvanic Cells
2016In the last chapter, we learned a lot about Galvani potential differences across different individual interfaces and the usefulness of these potential differences, but we did not get to know how they can be measured. The problem is that it is impossible to measure the Galvani potential difference across a single interface in a half-cell directly ...

Solid electrolyte galvanic cell under load
Journal of Applied Electrochemistry, 2001Relationships are derived which describe the voltage of and the ionic and electronic currents through a solid electrolyte galvanic cell under load as an explicit function of the independent variables. These relationships result from an appropriate extension of the classical Wagner approach for the open circuit case to the conditions of a cell in charge

Redox Potential and Galvanic Cells
2019Following the concepts illustrated within the previous chapter, an analogy is presented here between the working mechanisms of galvanic cells and biological redox reactions. These processes are explained here to underline the working principle of power conversion within biomass generation and to provide students with clear information on the reactions ...

ChemInform Abstract: GLASSY ELECTROLYTE GALVANIC CELLS
Chemischer Informationsdienst, 1980AbstractDie elektrolytischen Eigenschaften (wie Gesamt‐ und Elektronenleitfähigkeiten, Ag‐Überführungszahlen und Zers.‐Spannungen) der Gläser (I)‐(III), von denen (I) und (III) eine hohe Leitfähigkeit (um 10‐2Ω‐1cm‐1) besitzen und (II) eine vergleichsweise geringe (10‐4Ω‐1cm‐1) werden anhand der Ketten A‐C untersucht und durch Literaturwerte ergänzt.
