This paper presents the theoretical description of emfin a nonisothermal and convective system, with experimental data demonstrating its appropriateness.
In a thermodynamic consideration, approach by F#rland and Ratkje was chosen since their approach is thermodynamically rigorous, and the experiments have been carried out in an aqueous AgNO, system.
The experimental results indicate that emfmeasured in a nonisothermal and convective system is mainly due to the so-called thermogalvanic cell.
