To provide a thermoelectric conversion hydrogen battery capable of efficiently converting thermal energy into electric energy using hydrogen absorbing alloy.
This thermoelectric conversion hydrogen battery comprises a first hydrogen absorbing device (a), a second hydrogen absorbing device (b), and a heat supplying means (c). The first hydrogen absorbing device (a) includes the first hydrogen absorbing alloy of releasing hydrogen at a low temperature or higher . In the second hydrogen absorbing device (b), a hydrogen gas chamber, a hydrogen separation membrane for separating hydrogen molecules into electrons and protons, a proton conduction membrane for re-changing the separated protons into the hydrogen molecules by passing them therethrough and for supplying the hydrogen molecules into the hydrogen gas chamber or the second hydrogen absorbing alloy, and a second hydrogen absorbing alloy releasing of hydrogen at a high temperature, are arranged in this order. The heat supplying means (c) adjusts the temperatures of the first and the second hydrogen absorbing alloys. The hydrogen separation membrane is used for a positive electrode, and the second hydrogen absorbing alloy is used for a negative electrode, or vice versa, thus converting thermal energy of the second hydrogen absorbing alloy into the electric energy.
