POWER GENERATING DEVICE EMPLOYING HYDROGEN ABSORBING ALLOY AND LOW HEAT

WIPO Patent Application WO/1997/048887

A1

A power generating device employing hydrogen absorbing alloy and low heat wherein two types of hydrogen absorbing alloys that can reversibly absorb and release hydrogen gas and have different thermal equilibrium hydrogen pressure characteristics are used and loaded, respectively, in a first hydrogen absorbing alloy heat exchanger container (1) and a second hydrogen absorbing alloy heat exchanger container (2) that are ventilably connected to each other, wherein at least two sets of heat generating cycles are provided that employ heat generated when hydrogen gas is moved between the first hydrogen absorbing alloy heat exchanger container (1) and the second hydrogen absorbing alloy heat exchanger container (2), wherein a low temperature side hydrogen absorbing alloy hydrogen compound that has a higher equilibrium hydrogen pressure at the same temperature is heated by low quality heat sources (8, 9, 10), wherein released hydrogen is absorbed by a high temperature side hydrogen absorbing alloy having a lower equilibrium hydrogen pressure to thereby obtain heat having a temperature that is higher than the temperature of the low quality heat sources, and wherein cooling medium vapour is generated by the heat so obtained so that power generation can be effected by a gas turbine (13).
