Abstract:

Development of the chemical method of converting heat to electrical energy is reported. Parallel development of systems based on the Cu-Te chlorides and Sb chlorides has continued. The former system has afforded the more favorable galvanic cell characteristics. Although this system is technically feasible, practical regeneration of the anode liquid has not been achieved because of complications in separating the resulting TeCl2 and Cl2 gases at the regeneration temperatures. Separation as a result of the selective solubility of TeCl2 in a molten carrier salt gives promise of becoming practical, but at present the solubility of 1-3 is below the 20 solubility deemed necessary. The principal effort with the SbCl3 system has been to obtain satisfactory galvanic cells characteristics, a problem that originates with the very low ionic conductivities of the Sb chlorides. Specific conductivities of 0.002 and 0.007 were found practical at 75 C for the cathode and anode systems, respectively. A solid ionic electrolyte based on PbCl2 doped with KCl has been developed to a degree satisfactory for the Sb chloride system. Author
