METHOD AND DEVICE FOR SUPPLYING A HYDROGEN INTERNAL COMBUSTION ENGINE OF A MOTOR VEHICLE WITH HYDROGEN

The invention relates to, inter alia, a device for supplying a hydrogen internal combustion engine of a motor vehicle with hydrogen. The device has a storage tank for a fluid containing a carrier agent enriched with hydrogen. The device has a first heat exchanger for heating the fluid by transferring heat from a coolant of the hydrogen internal combustion engine and a second heat exchanger for additionally heating the fluid by transferring heat from an exhaust flow of the hydrogen internal combustion engine. The device provides a highly energy-efficient system that makes appropriate use of the thermal energy in the exhaust and the thermal energy in the coolant.
