  • Patent number: 10946712
    Abstract: A vehicle includes a fuel cell unit with which is associated a first coolant circuit, with a second coolant circuit associated with the interior of the vehicle, in which is held a coolant of lower temperature relative to the coolant of the first coolant circuit. Given higher demand for cooling capacity in the first coolant circuit, a valve is opened by a control device, independently of the heat demand in the second coolant circuit, to open a first connecting conduit between the first coolant circuit and the second coolant circuit, and thus, using a second connecting conduit, forms a common ring conduit for the first coolant circuit and the second coolant circuit with the accumulated coolant from the first coolant circuit and the second coolant circuit.
