Definitions
- the invention relates to a vehicle with a fuel cell according to the preamble of claim 1 and a method for its operation according to the preamble of claim 6.
- JP 2019-075254 A2 describes a fuel cell system comprising a fuel cell in which hydrogen and oxygen are electrochemically reacted and water is generated by the electrochemical reaction, water storage parts for storing water collected in the fuel cell, a heat exchanger that releases heat from the exchange of a heat exchange medium that receives heat from the fuel cell, a spray part for spraying water from the water storage parts onto the heat exchanger to cool the heat exchanger using latent heat of vaporization, and an abnormality determination part for determining an abnormality related to water spraying of the spray part.
- the abnormality determination part performs an abnormality determination based on the difference of the theoretical heat release of the heat exchanger when no water is sprayed onto the heat exchanger and an actually measured heat release of the heat exchanger when water is sprayed onto the heat exchanger.
- the invention is based on the object of specifying a novel vehicle with a fuel cell and a novel method for its operation.
- the object is achieved according to the invention by a vehicle with a fuel cell having the features of claim 1 and by a method for operating a vehicle with a fuel cell having the features of claim 6.
- a vehicle according to the invention comprises at least one fuel cell, a cooling system with at least one cooler for cooling the fuel cell, a container for collecting water generated in the fuel cell, a plurality of nozzles arranged in front of the cooler in the direction of travel for directing or spraying water from the container onto the cooler or into an air stream flowing through the cooler, a pump for conveying the water from the container to the nozzles, and a controller that is configured to control and/or regulate the pump with regard to the amount of water conveyed depending on the outside temperature and a temperature of the cooling system.
- the vehicle is designed as a commercial vehicle, wherein the cooler is arranged on a roof or in the region of the roof of the vehicle, wherein the container is arranged in a lower region of the vehicle.
- Spraying water onto a warm and/or hot radiator improves cooling performance. Cooling performance is achieved by evaporating the water. This allows energy savings, an improvement in the efficiency of the radiator and therefore a better efficiency of the overall system including the fuel cell. This results in a reduction in the ecological footprint, as more range is achieved with the same use of primary energy.
- Fig. 1 is a schematic view of a commercial vehicle with fuel cell drive.
- Figure 1 is a schematic view of a commercial vehicle 1, in particular a tractor for a semitrailer.
- the commercial vehicle 1 has a drive based on one or more fuel cells.
- a technology tower 3 is arranged behind a cabin 2 of the commercial vehicle 1, in which one or more hydrogen tanks 4 are arranged.
- a cooler 5 is arranged on a roof of the cabin 2 or on the technology tower 3 in the roof area.
- a fuel cell vehicle generates a lot of waste heat. This is further increased by the need for cooling power when the vehicle brakes. If no recuperation is possible, then electrical energy must be converted into heat, which must be dissipated via the cooler 5.
- one or more nozzles 6 are arranged from which water can be sprayed onto the radiator 5.
- the water is generated as a spray mist by the fuel cell, discharged from it and collected in a container 7.
- a container 7 In a commercial vehicle 1, for example, around 50 l of water can be produced per hour.
- the water is introduced via the nozzles 6 as a water flow or as a spray mist into an air stream which flows through the radiator 5, or is sprayed directly onto the radiator 5.
- the cooler 5 is blown by the air flow, for example the airstream FW while driving.
- the nozzles 6 are arranged in this air flow and can be designed similarly to the nozzles for the cleaning water on a windshield.
- the nozzles 6 are supplied with water from the container 7.
- the entire cooler 5 is wetted and the cooler 5 is additionally cooled as a result of the evaporation enthalpy, for example by about two to three degrees more than without the spraying.
- the container 7 for collecting the water from the fuel cell is located, for example, in a lower area of the commercial vehicle 1.
- the water is pumped from the container 7 to the nozzles 6 by means of a pump (not shown).
- the spray mist generated by the fuel cell can also be applied directly to the cooler 5.
- a control (not shown) can be provided which decides when and how much water is sprayed depending on at least one temperature, for example the outside temperature and/or a temperature of the cooling system of the commercial vehicle 1.
- a collecting device for example a tub or channel, can be provided behind the cooler 5 to collect part of the sprayed water that may not have evaporated.
- An outlet from this collecting device, for example to the container 7, can be guided along an ascending and thus warmer line to the cooler 5 and wet it. In this way, this line is also additionally cooled as a result of evaporation enthalpy and the cooling effect is increased.
