(US5310608-A)      The electric storage battery comprises a solution containing redox ion couples having a temperature-dependent redox potential, and a low-temperature electrode and a high-temperature electrode for generating a temperature difference disposed in the solution. A membrane film device which is impervious to the redox ion couples is disposed between the low-temperature electrode and the high-temperature electrode.    A low-temperature power electrode is disposed between the low-temperature electrode and the membrane film device, and a high-temperature power electrode is disposed between the low-temperature electrode and the membrane film.    USE -   Thermal to electrical energy conversion, e.g. waste heat, fuel cell heat, vehicle-based exhaust gases and engine heat, hot springs, geothermal heat, incinerators, air conditioners, radioisotopes and atomic reactors.    (JP6140082-A)      The battery comprises a solution (2) of redox ion couples with a temp.-dependent redox potential. A low temp. electrode (1) and a high temp. electrode (3) generate a temp. difference when positioned in the solution.    A membrane film (6), impervious to redox ion couples, is located between the two electrodes. A low temp. power electrode (7) is located between the low temp. electrode and the membrane film, and a high temperature power electrode is located between the high temp. electrode and the film.    ADVANTAGE -   Power is delivered when temp. difference is eliminated between power electrodes.
