A method for thermal management of fuel cells of a vehicle is provided, the fuel cells (FCS) being cooled through a main circuit (HTCC) where at least one pump (P, P1) is arranged to circulate a cooling liquid through a radiator (R). The method includes a step of selectively thermally connecting the main circuit to a secondary circuit (LTCC) arranged to cool at least one subsystem of the vehicle, such as the vehicle cabin, and/or batteries arranged to cooperate with the fuel cells (FCS), or other subsystems of the vehicle that require cooling or refrigeration.

A cooling system comprises a liquid storage tank and liquid disposed within the liquid storage tank. A first heat exchanger is immersed within the liquid, wherein refrigerant from an air conditioning system flows through the first heat exchanger. A second heat exchanger is also immersed within the liquid, wherein coolant from a load cooling system flows through the second heat exchanger.
