Definitions
- the invention relates to a device for discharging liquid from a
- Fuel cell systems are known from the general state of the art. The functionality is essentially that of hydrogen and oxygen electrical energy and product water is produced. The resulting product water is discharged together with exhaust gases from the area of the fuel cell. In order to separate the liquid water from these exhaust gases, typically water separators are provided in the fuel cell system. In this way, on the one hand the leakage of liquid water from the fuel cell system can be prevented and on the other hand a possible freezing of line elements by this liquid water when the fuel cell system is operated at temperatures below freezing and in particular turned off.
- water separators are also typically present in the recirculation, to deposit incurred product water and not returned to the fuel cell.
- liquid water could wet parts of the fuel cell, which would adversely affect the functionality of the fuel cell.
- Fuel cell system it is now crucial that, although the Water is drained from the water from time to time that the present in products and educts of the anode side (residual) hydrogen but not or only in a minimal amount of the environment.
- valve device Flow direction of the water to be drained before the valve device. If the valve device is then closed as soon as liquid is no longer present in the region of the capacitive sensor, then, with a suitable distance between the sensor and the valve device following in the flow direction on the sensor, the escape of gas can be completely prevented or with a correspondingly smaller distance to one tolerable minimum can be reduced.
- the object of the present invention is now to provide a device for discharging liquid water from a water separator in a
- a method for draining liquid with such a device specified provides that the device comparable to the prior art, a liquid sensor, a valve device and the
- Valve device in response to a measured value of the liquid sensor controlling control unit comprises. Unlike the prior art, the structure is chosen so that the sensor is arranged downstream of the valve device in the flow direction. This allows the sensor to come into contact with liquid only when it is drained accordingly. Since the sensor thus only temporarily with the
- a particular advantage of the device according to the invention lies in the fact that, according to a preferred development, it can use a liquid sensor which has two temperature sensors and a tempering element in
- Liquid gas mixture or the flowing liquid in the region of the sensor safe, simple and reliable detection of the liquid portion of the fluid can be realized.
- an ultrasonic sensor to be used.
- an ultrasonic sensor which is also very well suited for the detection of liquid in flowing media, can by the inventive arrangement in
- Embodiment of the device according to the invention can be used.
- the device according to the invention may further provide, according to an advantageous embodiment, that the water separator in an anode circuit of the
- Fuel cell system is arranged.
- Containing residual hydrogen it is crucial that when draining the liquid no gas or only a minimum predetermined amount of gas with the environment comes. This can reduce hydrogen emissions while minimizing the loss of hydrogen which is lost to the atmosphere and can not be effectively converted into electrical energy in the fuel cell.
- the amount of condensate accumulating in the water separator is roughly estimated. This can be done, for example, based on the performance of the fuel cell. In principle, it would also be conceivable to estimate this on the basis of the quantity of added hydrogen and / or the metered air. Furthermore, it would be conceivable, instead of an actual estimate, which can be done for example via a simulation of the operation of the fuel cell, to set an empirical value and the amount of accrued
- the valve device of the device is opened. After that, three main cases are distinguished.
- the sensor detects liquid water, wherein the valve device remains open at a volume flow of liquid water above a predetermined limit. In this case, water should be drained as desired. If the volume flow of liquid water which is detected by the liquid sensor is smaller than this predetermined limit value over the course of time, then the valve device is closed again, since in this case only a comparatively small amount of residual water from the water separator remains flows.
- Temperature sensors and a Temper michselement in the manner described above can thus be implemented a safe and reliable method, which operates in normal operation with minimal hydrogen emissions and ensures a safe and reliable discharge of liquid from the water.
- the fuel cell system can be safely operated without liquid water penetrating into undesired areas where it, for example, wets active areas and / or in undesired areas when the facility is switched off
- Figure 1 is a principle indicated fuel cell system in a vehicle.
- Fig. 2 shows a device according to the invention
- Fig. 3 shows an exemplary embodiment of the liquid sensor according to the invention.
- a fuel cell system 1 in a vehicle 2 indicated in principle can be seen in a highly schematic manner.
- the fuel cell system 1 is intended to provide electrical power for the vehicle 2, in particular drive power for the vehicle 2. It consists essentially of a fuel cell 3, which has a cathode space 4 and an anode space 5.
- the cathode compartment 4 is air in a conventional manner via an air conveyor 6 as
- Exhaust line such as a turbine for the recovery of residual energy in the exhaust air.
- Hydrogen is supplied from a compressed gas reservoir 8 via a pressure regulating and metering device 9 to the anode compartment 5 of the fuel cell 3. Not consumed
- Hydrogen passes in a conventional manner to the anode compartment 5 via a recirculation line 10 with a recirculation conveyor 11 back to the input of the anode compartment 5 and is the anode compartment 5 mixed with fresh hydrogen supplied again.
- water and inert gas accumulate over time.
- the water is the product water from the fuel cell 3, wherein here a small part of the product water in the region of the anode compartment and the larger part in the region of the cathode compartment 4 is formed.
- the inert gas is typically nitrogen, which passes through the
- Membranes of the fuel cell 3 constructed as a PEM fuel cell
- a water separator 12 is provided in the fuel cell system 1 shown here. Via a device 13 for discharging water, the liquid water is discharged to the environment of the vehicle 2. Likewise, it could be discharged, for example, in the exhaust air stream 7 and evaporated in this and / or atomized. It is also possible to store and / or use the value of the water in the vehicle 2.
- the invention lies in the device 13 for discharging the liquid water. This is indicated in the illustration of Figure 1 only as a box. In the illustration of Figure 2, a concrete structure of the device 13 according to the invention is shown. Again, the water separator 12 and a part of the recirculation line 10 can be seen. In the direction of gravity down leads from the water separator 12, a line member 14, in the region of the device 13, which is surrounded by a dash-dot line here, is arranged. It consists in the direction of flow of the liquid water from a valve device 15 and a liquid sensor 16.
- the liquid sensor 16 detects the presence of liquid. This will be reported to the controller 17.
- the liquid sensor 16 is able to distinguish between no liquid and at least two different amounts of liquid in the discharged fluid. The amount of liquid above one
- predetermined limit value is hereinafter referred to as a large amount of liquid below a predetermined limit as a small amount of liquid.
- a predetermined limit value is hereinafter referred to as a large amount of liquid below a predetermined limit as a small amount of liquid.
- the controller 17 estimates the amount of accumulated
- Product water or condensate from. This can in particular be based on the electrical power P of the fuel cell 3 added up or integrated over time. This is indicated in the representation of FIG. 2 by the arrow 18 labeled P, which supplies corresponding data to the control unit 17.
- the first state which typically occurs rarely in regular operation, since it presupposes a misjudgment of the accumulated amount of condensate, would be that none Liquid in the region of the liquid sensor 16 is present.
- the controller 17, the valve device 15 close immediately. Only by the line length between the valve device 15 and the liquid sensor 16 and a possible time delay for detecting the measured value of the liquid sensor 16 will then lead to the discharge of a small amount of gas. However, this amount is typically very low and, even if they are hydrogen or
- the second possible case is that a large volume flow of liquid water is detected according to the above definition.
- the valve device 15 remains open.
- a small volume flow of liquid water is detected directly or the volume flow of liquid water drops during the discharge of the detected large volume flow to a now detected small volume flow, then by the controller 17, the
- Valve device 15 is closed.
- valve device 15 Whenever the valve device 15 is closed, for whatever reason, the condensate amount estimate previously set to "zero" restarts and the process starts again, except for the rarely occurring first case, the escape of hydrogen to the Prevents environment and at the same time achieves a safe and reliable discharge of the liquid, so that flooding of the fuel cell 3 and / or the recirculation line 10 can be safely and reliably avoided by a "spill" water separator.
- a particularly suitable liquid sensor 16 is short in the following
- the liquid sensor 16 consists of a first temperature sensor 19 and a temperature control element 20 following in the direction of flow on this temperature sensor 19, which is in heat-conducting connection with a second temperature sensor 21.
- the tempering 20 includes a
- Base body 22 This can be formed in particular of a good heat-conducting material, for example of aluminum. Depending on the materials used are also ceramic materials or corresponding feeds conceivable to the
- Base body 22 of the tempering 20 chemically resistant to the ingredients of the liquid resistant.
- the base body 22, as shown here, have a plurality of openings 23 through which the fluid flows.
- the tempering element 20 can be heated or cooled, for example, to a predetermined temperature value.
- the temperature of which is known from the temperature sensor 19 heating or cooling of the base body 22 then occurs.
- the resulting temperature change can be detected reliably and reliably via the second temperature sensor 21.
- the measurement is based on the knowledge that the fluid has a greater heat capacity when there is a liquid phase in the fluid.
- the fluid causes a greater change in the liquid phase by means of the
- Temperiansselements 20 set temperature of the flow around the base body 23, as would be the case by a fluid without the presence of a liquid phase or with a smaller proportion of liquid phase. By comparing the measured in the region of the first temperature sensor 19 temperature of the fluid and in the tempered by means of the Temper michselements 20 main body 22 as a result of supplying or flowing through the fluid-adjusting temperature on
- Temperature sensor 21 can thus easily and efficiently detect the presence of liquid. In particular, the amount of liquid present in the fluid can be confined safely and reliably. Since this works ideally in particular with flowing fluids, such a fluid sensor 16 is outstandingly suitable for the arrangement after the valve device 15, as embodied in the device 13 described here.
