Redox Potentials and Galvanic Cells

2016
In 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 ...

The electromotive force of a galvanic cell

1980
As described previously, the galvanic cell is a system constructed from a set of thermodynamic phases such that an electric current can exist and a chemical reaction can proceed in the system. It seems to be a reasonable starting point to describe a system in which two different electrolyte solutions are placed in contact with another.

Unfolding the Hidden Reactions in Galvanic Cells

Electrocatalysis, 2018
The relationship between the potential of the cell reaction (Ecell), the entropy change (ΔS), and the enthalpy change (ΔH) is well established. Yet, there is surprisingly a very narrow range of experimental aqueous galvanic cells that follow thermodynamic predictions.

The galvanic cell with an oxygen electrode

1980
Let us consider the following galvanic cell (Fig.34). In the presence of an electric current the chemical reaction is: $$Na + 1/4 {O_2} + 1/2 {H_2}O \to NaOH$$ Open image in new window Fig. 34 Glavanic cell involving an oxygen electrode and a non-uniform electrolyte solution.

Electrode Architecture in Galvanic and Electrolytic Energy Cells

Angewandte Chemie International Edition, 2016
AbstractElectrodes in galvanic and electrolytic energy cells are complicated structures comprising redox‐active materials, ionic/electronic conductors, and porous pathways for mass transfer of reactants. In contrast to breakthroughs in component development, methods of optimizing whole‐system architectural design to draw maximum output have not been ...

Redox Potential and Galvanic Cells

2019
Following 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 ...

Galvanic cells including cobalt-chromium alloys

Acta Odontologica Scandinavica, 1980
Galvanic 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 ...
