A vehicle using hydrogen absorbing alloys includes: 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 section for passing hydrogen to and fro among the plurality of hydrogen absorbing alloy storing vessels; and a heating section for heating a low pressure hydrogen absorbing alloy which has the lowest hydrogen equilibrium decomposition pressure among the plurality of hydrogen absorbing alloys, using the combustion heat from fuel of an internal combustion engine or an external combustion engine of the vehicle as a heat source. Heat of reaction generated by absorption or desorption of hydrogen is utilized for heating or cooling the air in a passenger compartment or a component of the vehicle. The connecting section includes a hydrogen gas storing vessel.
