Electrolyte contact geometric parameters

Figure 1. Geometric parameters characterizing the semiconductor-electrolyte contact...

In the geometric representation of the composition of the membrane, the volume fraction of each component in each layer is described quantitatively by corresponding geometric parameters. In the electrochemical part of the model, each layer is treated as a set of two resistors and all sets, whose number equals the number of layers, are arranged in series forming an equivalent electrical circuit. Summation of the resistances of the layers expressed with appropriate equations leads to the final formula on specific conductivity of the membrane. Calculations based on the model require measurements of the conductivity of the membrane in contact with electrolyte solutions of different concentration.
