摘要
In this work we developed a concept and calculated the efficiency of a hybrid of thermogalvanic and concentration galvanic cells. The proposed device consists of two vessels with the sodium hydroxide solution of various concentrations, Ag/Ag2O or Fe/Fe(OH)(2) electrodes, chamber for water vapor transferring and the ion bridge or a porous partition. Concentration difference is kept because of two factors: distillation of sodium hydroxide solution in temperature gradient and dependence of solubility of sodium hydroxide on temperature (NaOH center dot H2O crystalline hydrates melting). Calculation shows that the efficiency of the hybrid cell may be about 10% of Carnot efficiency.
