Patent ID: 7846602

Claim:
A thermoelectric conversion apparatus comprising: an evaporator for heating a working medium in liquid-phase to evaporate said working medium; an electric generator having an anode electrode for being supplied with a reactive gas and a cathode electrode for being supplied with said working medium evaporated by said evaporator, said electric generator forming a concentration cell for electric power generation when said anode electrode is supplied with said reactive gas and said cathode electrode is supplied with said evaporated working medium; a gas-liquid separator for being supplied with a mixed gas of said reactive gas which has reacted in said concentration cell and said working medium, from said cathode electrode, and condensing said working medium to separate said mixed gas into said working medium and said reactive gas, wherein said gas-liquid separator is supplied with said mixed gas and an unreacted reactive gas discharged from said anode electrode; a first supply passage for supplying said reactive gas separated by said gas-liquid separator to said electric generator; and a second supply passage for supplying said working medium in liquid phase separated by said gas-liquid separator through said evaporator to said electric generator.
