Construction of
Half Cell.
Half cells (coin cells) were built with carbon (ROHG or graphite) electrodes and lithium metal disc as the counter electrodes.
The module electrode was optimized according to the current technological levels in photovoltaic industry development, and a 16-wire structure with a diameter of 200 [micro]m combined with
half cell was proved to achieve the most power output.
The volume of each solution in the
half cell was 50 mL.
Elsener, 2001 [11] For interpretation of half-cell potential readings, it requires precise understanding of corrosion protection mechanisms and good knowledge and experience in
half cell potential mapping.
These errors are compounded because of any lateral movement of the CIPS
half cell as the surveyor wanders from the centerline.

half cell potentials of steel reinforcement in contaminated concrete in the absence (SAMPLE 1) and presence (SAMPLE 2) of SLS during 480 days.
It is remarkable that optimal cell size is still the
half cell. Only by the highest cell quality (42 mA/[cm.sup.2] photocurrent) and the narrowest tab width (1 mm), a very little benefit in the case of the one-third cells is observable (see Figure 11).
It can be observed from the results that the voltage of the
half cell varies with changes in the concentration of the phenol.
The "close" potential is the potential between the pipe and a stable
half cell placed extremely close to the pipe surface.
