Abstract

An electrolytic calorimeter employing a heat flux transducer (HFT) has been developed. By means of this apparatus the single electrode Peltier heat for the anodic chlorine evolution reaction in the electrolysis of molten NaCl-ZnCl2 using a β-alumina diaphragm was measured. The value of the single electrode Peltier heat obtained by such a method was 0.697 J C-1 at 377° C, which is very close to the value 0.614 J C-1 previously determined by a thermoelectric power measurement. The coincidence between the two methods indicates that a thermoelectric power measurement is quite valid for determining the single electrode Peltier heat.
