The present invention relates to a cooling device (10) for at least partial cooling of a fuel cell system (100) of a drive system for a vehicle (200), having a radiator device (20) with cooling ducts (22) for carrying a coolant (K) as part of a cooling circuit (150) for the fuel cell system (100), and with an inlet portion (40) for admitting an air flow (LS) along an inlet direction (ER), wherein the radiator device (20) has at least two separate radiator portions (24) having different throughflow directions (DR) transverse to the inlet direction (ER) for the air flow (LS) in order to cool the coolant (K) in the cooling ducts (22), and wherein between the at least two radiator portions (24) there is formed an inlet gap (30) to guide the air flow (LS) from the inlet portion (40) to the radiator portions (24), further having a spray device (50) with at least one spray valve (52) with a spray direction (SR) into the air flow (LS) in the inlet portion (40) and/or in the inlet gap (30) and with a water duct (54) for supplying water (W) to the at least one spray valve (52).
