Characterisation of electrochemical cell for textile electrode studies and quality control

Characterisation of electrochemical cell for textile electrode studies and quality control 

In this chapter, an attempt is made to characterise an electrochemical cell and to describe a method for quality control of textile electrodes by investigating the behaviour of textile electrodes and comparing the obtained results. 

The characterisation of an electrochemical cell is discussed in order to understand the parameters that are important and the relationships according to which they contribute to the output signal of the electrochemical cell. This characterisation will be done with electrodes made of palladium, which is a precious metal and enables the electrodes to behave in a relatively inert manner, owing to their stability and the fact that they do not significantly complicate the behaviour of the electrochemical cell. The method of concern is electrochemical impedance spectroscopy (EIS), which is explained in Chapter 2 section 2.31. 

Relationships between output signal, which in fact is an impedance (R) of the system, and concentration of electrolyte (c), electrode surface area (A) and distance between electrodes (d) will be investigated in order to produce an equation which shows the interrelationships between these parameters. At this moment, a general equation can be formulated as follows  

The electrochemical cell consists essentially of two PVC plates, as shown schematically in Fig. 9.1. The electrodes are positioned at the inner side of
