Abstract The thermodynamic principles related to thermocells are reviewed. The equation for the potential of a cell with a single component electrolyte, such as a fused or solid salt, is similar to that for a cell with aqueous solution electrolyte after the Soret equilibrium has been established. In particular the total "transported entropy" of the ionic species reacting at the electrodes may be obtained without any complication from transference numbers, and values of this quantity are given for several cells, The meaning and measurability of the partial molal entropies of single ions in electrolytes are considered. It is found that the transported entropy of metal ions in fused salts is approximately equal to estimated values of the partial molal entropies of these ions; hence the entropies of transfer are small. In solid electrolytes the entropies of transfer are sometimes large and are discussed in terms of the probable conductance mechanisms.
