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.
Claims15
A method for parking heating of at least the passenger compartment of motor vehicles operated at least partially on hydrogen and having a hydride reservoir, wherein the hydride reservoir is a LT/HT hydride combination, comprising supplying the heat capacity of the HT reservoir, present after the engine is shut off or produced by charging with hydrogen, at least partially to the passenger compartment.
An apparatus for parking heating of the interior of a motor vehicle having an engine operated at least partially on hydrogen, comprising an LT/HT hydride combination reservoir means for supplying hydrogen which serves as fuel for the engine, and heat transfer means disposed in a heat-transferring connection between said reservoir means and the interior of the motor vehicle, for supplying the heat capacity of the HT reservoir at least partially to the interior of the motor vehicle.
