Abstract

The passenger compartment of a motor vehicle operated at least partially on hydrogen may be heated after the engine is shut off by using a LT/HT hydride combination reservoir as the hydride reservoir for the vehicle. The heat capacity of the reservoir, present after the engine is shut off or produced by charging the HT reservoir with hydrogen from the LT reservoir, is supplied at least partially to the passenger compartment.
