Patent ID: 7404461

Claim:
An electrical power train for a vehicle, the power train comprising: an electrical line to which the auxiliary loads are connected; a fuel cell connected to the electrical line, a first cooling circuit, providing the cooling of the fuel cell by means of a first heat-transfer liquid charge, the first cooling circuit comprising a first radiator for dissipating heat to the ambient atmosphere; an electrical energy management unit comprising a fuel cell control module; a control device available to the driver of the vehicle in order to control deceleration of the vehicle, the control device being connected to the management unit; at least one electrical machine connected to at least one driving wheel connected to the electrical line by means of an electronic control module for the electrical machine; an electrical dissipation element; and means for ordering the fuel cell control module to stop the process of producing electrical energy while connecting the dissipation element to the electrical line, in the case of a demand for deceleration and when the management unit detects that the power absorbed by the auxiliary loads is less than the power sent over the electrical line.
