Method for quality control of textile electrodes

For the experiments described in this chapter, use was made of textile electrodes of stainless steel instead of palladium sheets, which were used for the characterisation of the electrochemical cell. The aim of this section is to investigate the behaviour of these textile electrodes in the electrochemical cell and to compare the results obtained with those described in section 

For this purpose, the starting situation in this section is reflected by Equation9.1 and, depending on the results obtained, will show whether this equation is still valid and, if so, under which conditions. Possible differences in results between those described in this section and those in section9.2 need to be explained by the fact that a textile structure is used as electrode material, since this is the only modification of the electrochemical cell characterised in section9.2 and used for the studies described here in section 

2 Characterisation of the electrochemical cell with textile electrodes 

Similar to the experiments carried out at palladium electrodes and described in Chapter3, the concentration of electrolyte (c), the electrode surface area (A) and the distance between the electrodes (d) will be studied as a function of type of textile structure. In this work, three structures will be studied knitted, woven and non-woven textile structures, all obtained from stainless-steel fibres. To complete the data of this work, palladium sheets will also be inserted in the study as a fourth set of electrodes. Therefore, for palladium electrodes, the work described in section 9.2 will actually be repeated here in order to have a direct comparison between results obtained with palladium electrodes and textile electrodes. Of course, correlation with the data obtained in section 9.2 will be verified. 

A first parameter to be investigated is the concentration of the NaCl solution. Electrochemical cells with electrolyte concentrations of 1x10 lx 10 2,1x10 3 and lxl0 4moll1 NaCl were prepared. Impedances at these
