Abstract

The disclosure relates to a system having an electric machine with a superconductive component cooled using a cryogenic liquid, and in particular to the full utilization of the refrigeration power available from vaporization of the cryogenic coolant. The system also has a fuel cell, in which an operating medium may be reacted to provide electrical energy. The coolant is fed in liquid form to the superconductive component to cool the component, utilizing the vaporization enthalpy of the coolant. The coolant is then fed in gaseous form to a further component of the machine to cool the component, utilizing the heating enthalpy of the coolant. The now heated coolant is fed to the fuel cell, which uses the coolant supplied to the fuel cell as an operating medium and reacts it.
