1. A system for thermal management of fuel cells (FCS) of a vehicle, the system comprising:
a main circuit (HTCC) comprising a radiator (R) and at least one pump (P, P1) configured to circulate a cooling liquid through the radiator (R) and the fuel cells,
a secondary circuit (LTCC) arranged to cool a subsystem of the vehicle, wherein the subsystem arranged to cooperate with the fuel cells (FCS), wherein the secondary circuit comprises a secondary circuit tank (LTT) cooled directly or indirectly by a chiller circuit (Chiller Circuit), wherein the chiller circuit comprises a heat pump supplied by the fuel cells,
a heat pairing exchanger (X1) arranged to couple the main circuit with the secondary circuit, and
a first bypass means (BP, V2) arranged to selectively thermally connect/disconnect the main circuit from the secondary circuit.
