are summarised in Table 9.2. The bold value for
d
= 112 mm is in acceptable
correlation with the value obtained in the previous section. In addition, with
the knowledge of the data of
k

from Table 9.2, it is possible to calculate the
results for
k

as a function of electrode surface area
A
and distance between
the electrodes
d
(Table 9.3). Again, it can be seen that there is good corre-
lation between the values in bold and those obtained in the previous sec-
tions under the same experimental conditions.

Method for quality control of textile electrodes
9.3.1
Introduction
For the experiments described in this chapter, use was made of textile elec-
trodes 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 electrochemi-
cal cell and to compare the results obtained with those described in section
