Patent ID: 7377235

Claim:
A fuel supply system for at least one of an internal combustion engine operable using hydrogen or a fuel cell, said fuel supply system comprising: a hydrogen tank, which is provided for storing deep-cooled, liquid hydrogen, and a heat exchanger, which is provided for preheating the deep-cooled hydrogen, the heat exchanger including: at least one fuel intake, which has a fluid connection to the hydrogen tank; at least one fuel outlet, which has a fluid connection to the fuel intake, via which preheated hydrogen is discharged from the heat exchanger, at least one coolant intake, via which hot coolant from a coolant loop of the internal combustion engine and/or the fuel cell is supplied to the heat exchanger, and at least one coolant outlet, which has a fluid connection to the coolant intake, via which cooled coolant, which has delivered heat to the hydrogen, is discharged from the heat exchanger, wherein the heat exchanger is enclosed by a fluid-tight mantle, an intermediate space being provided between the heat exchanger and the mantle, which has a fluid flowing through it, which delivers heat to the heat exchanger and insulates the heat exchanger in relation to its surroundings.
