“…For high values of 8, ie temperature difference, the convection transport of heat becomes important, so that normalised efficiency reaches its limiting value. In general, we approved the conclusion of [7][8][9][10] that the convection transport can increase the efficiency of TGC up to 2-3 times.…”

“…This prevents the systematic research of all possible variants of TGC. Actually, only a few calculations for some variants of TGC, more or less related to those real systems that already exist, have been made [9,10]. This is why it is necessary to work out a reasonably simple theoretical model which can help in studies of the principal properties of TGC and also provide a theoretical estimation of the efficiency of present TGC constructions.…”

Abstract-The functioning of thermogalvanic cells has been studied theoretically. The analysis for the simplest case which accounts for only diffusion transport of the reacting substances from one electrode to another has been made. The simple relation for thermodynamic efficiency of such energy sources was obtained. The diffusion-migration transport for the horizontally arranged cell and the diffusionconvection transport for the vertically arranged cell were studied in detail. The original mathematical methods for solving transport equations were used. Analytical results for the concentration distribution and the current-voltage curves were calculated. The principal role of electrode kinetics (fast changing of the equilibrium electrode potential with the temperature) was shown. Finally, the general algorithm for improving thermogalvanic cells was proposed.
