Abstract: A fuel cell vehicle includes a cooling system with at least one radiator for cooling the fuel cell, a container for collecting water generated in the fuel cell, a plurality of nozzles arranged in front of the radiator in the direction of travel for directing or spraying water from the container onto the radiator or into an air flow flowing through the radiator, a pump for conveying the water from the container to the nozzles, and a controller configured to control and/or to regulate the pump with regard to the quantity of water conveyed, depending on the outside temperature and a temperature of the cooling system. The vehicle is a commercial vehicle. The radiator is arranged on a roof or in the region of the roof of the vehicle and the container is arranged in a lower region of the vehicle.

Abstract: A heat exchanger for heat exchange between a first fluid and a second fluid is provided that includes: a block for guiding the first fluid and the second fluid separately and in a heat-exchanging manner, and a fluid connection for the first fluid. The block comprises a housing provided with a chamber through which the second fluid can flow, and a block end element for the fluid-tight separation of the chamber and the fluid connection. The housing can be provided for connecting the block to the fluid connection. The block end element is not used to connect the block to the fluid connection but rather preferably only the housing. The housing can be thickened accordingly in the region of the block connection. The fixing point for the block end element to the housing and the fixing point for the fluid connection to the housing are at a distance from each other.
