The development of the application systems using hydrogen absorbing alloys

Hydrogen absorbing alloys have a number of useful functions, such as an energy conversion. As an application to refrigeration, a new MH-refrigeration system for a freezing compartment by using a hydrogen absorbing alloy has been developed. The MH-refrigeration system is able to attain the temperature of the freezing compartment below -30°C. And as an application to separation and purification of hydrogen, MH-hydrogen purification system for generator cooling has been developed. MH-hydrogen purification system is expected to decrease the generator's windage loss, resulting higher generator efficiency.
