Vehicle using hydrogen absorbing alloys

A vehicle using hydrogen absorbing alloys, comprising:

• a plurality of hydrogen absorbing alloy storing vessels for independently storing a plurality of hydrogen absorbing alloys with a different hydrogen equilibrium decomposition pressure,
• a connecting means for passing hydrogen to and fro among said plurality of hydrogen absorbing alloy storing vessels, and
• a heating means for heating a low pressure hydrogen absorbing alloy which has the lowest hydrogen equilibrium decomposition pressure among said plurality of hydrogen absorbing alloys, using combustion heat of fuel of an internal combustion engine or an external combustion engine of said vehicle as a heat source,
• wherein, when said heating means heats said low pressure hydrogen absorbing alloy so that hydrogen is desorbed from said low pressure hydrogen absorbing alloy and then is absorbed by a high pressure hydrogen absorbing alloy of said plurality of hydrogen absorbing alloys, said high pressure hydrogen absorbing alloy having a hydrogen equilibrium decomposition pressure higher than that of said low pressure hydrogen absorbing alloy, exothermic heat generated by absorption of hydrogen by said high pressure hydrogen absorbing alloy is utilized for heating the air in a passenger compartment or a component of said vehicle;
• when hydrogen is desorbed from said high pressure hydrogen absorbing alloy, endothermic heat generated by desorption of hydrogen from said high pressure hydrogen absorbing alloy is utilized for cooling the air in said passenger compartment or said component of said vehicle;
• when hydrogen is desorbed from said high pressure hydrogen absorbing alloy and then is absorbed by said low pressure hydrogen absorbing alloy, exothermic heat generated by absorption of hydrogen by said low pressure hydrogen absorbing alloy is utilized for heating the air in said passenger compartment or said component of said vehicle;
• and
• said connecting means includes a hydrogen gas storing vessel and hydrogen flow adjusting valves, and said hydrogen gas storing vessel is arranged in parallel to at least one of said plurality of hydrogen absorbing alloy storing vessels.
