Pure polyaniline was prepared by dissolving of (2.59 g) of aniline hydrochloride in (50 ml) of distilled water and mixed with (5.71 g) from ammonium peroxy disulfate that dissolved in (50 ml) of distilled water in the Container of
electrochemical cell at room temperature and the doped sample was prepared in the same way but both of aniline hydrochloride and ammonium peroxy disulfate was dissolved in (1 M) of [H.sub.2]S[O.sub.4] for protonation PANI by [H.sub.2]S[O.sub.4]and dissolved in (1 M) of HCl for protonation PANI by HCl and then constant voltage was applied for a certain sample for two hours.
The group reported that their
electrochemical cell generated 13 ampere hours per gram of porous carbon (as the cathode) at a discharge potential of around 1.4 volts.
Hydronium ions pass through the proton exchange membrane, which is a solid electrolyte in
electrochemical cell.
An
electrochemical cell was designed for experiments previous to electrolysis.
The clean parts are then made the cathode in a
electrochemical cell consisting of 5% Potassium hydroxide and a stainless steel or otherwise inert anode at ambient temperatures for about 30 seconds.
