Definitions
- Temperature control housing for temperature control of components of a fuel cell system
- the present invention relates to a temperature control housing for temperature control of components of a fuel cell system, a fuel cell system with such a temperature control housing and a method for temperature control of a temperature control housing according to the present invention.
- fuel cell systems have devices for controlling the temperature of individual components.
- individual components in such fuel cell systems reach very high temperatures, so that they must be cooled.
- the operation of fuel cell systems produces water, which occurs in the anode exhaust gas and should be separated. For separation, the water must be separated from the anode exhaust gas.
- the disadvantage of the known solutions is that, particularly in special operating situations, such as a cold start or in particular the so-called frost start, i.e. a start of the fuel cell system at temperatures below 0° Celsius, uneven heat distribution and/or heating leads to undesirable cooling of the anode exhaust gas and/or or icing can occur within the separation device. This has the disadvantage that it can dry out and/or starting can only take place under difficult conditions or even not at all.
- known solutions are aimed at providing separating devices with electrical heating elements in order to enable heating using electrical power in cold start situations or forest start situations and thus to avoid icing.
- the known solutions are disadvantageous in that they either limit the operating range and in particular the possible starting conditions without the possibility of temperature control for the separation device.
- the known solution is disadvantageous because when using electrical heating devices, they increase the complexity, the costs and the space required.
- a temperature control housing is used for temperature control of components of a fuel cell system.
- a temperature control housing has a housing wall which encloses an interior housing space.
- a separation device for separating water from an anode exhaust gas for recirculation as recirculation gas is arranged within the housing interior.
- a temperature control housing according to the invention is characterized in that part of a cooling circuit for cooling system components of the fuel cell system for temperature control of the housing interior is arranged in the housing interior.
- the separation device is equipped with an anode exhaust gas inlet for receiving anode exhaust gas from an anode section of a fuel cell stack of the fuel cell system.
- the separation device has a recirculation gas outlet, for an outlet of the anode exhaust gas as recirculation gas into an anode supply section, for supply to the anode section of the fuel cell stack.
- the core idea according to the invention is based on providing the separation device with an active temperature control option.
- this active temperature control option is not formed by a separate temperature control device, as was ensured, for example, in the prior art by electrical heating means.
- the temperature control housing is used to heat the waste heat generated during operation of the fuel cell system from other components, here the system components, to control the temperature of the separator. Use device.
- the temperature control housing is equipped with part of the cooling circuit.
- the fuel cell system according to the invention is designed in particular as a PEM fuel cell system.
- a PEM fuel cell system it is necessary to dissipate the resulting waste heat in an appropriately designed cooling circuit.
- the membrane of a PEM fuel cell begins to be damaged at temperatures above 95 °C, as sulfonic acid chains decompose at these temperatures. Therefore, the fuel cell system has cooling circuits to protect the fuel cells and all other system components from overheating. This cooling circuit then usually has higher temperatures than, for example, a cooling circuit for the battery or the power electronics.
- the cooling water in the cooling circuit has a maximum temperature of around 90 °C to around 95 °C.
- system components are advantageously understood to mean all components of the fuel cell system, such as the balance-of-plant components and/or the high-temperature circuit components.
- a temperature control housing now uses this resulting waste heat from system components, in particular the waste heat from the fuel cell stack, and the fact that this waste heat is at least partially already in a coolant within the cooling circuit. Due to the structural design of a part of the cooling circuit within the housing interior of the temperature housing, it is now possible to use this waste heat at least partially to control the temperature of the housing interior. In a first step, it is irrelevant how the heat transfer takes place from the part of the cooling circuit to the housing interior. These can be simple heat transfer surfaces, but also more complex options, which take over the various heat transport phenomena, in particular heat conduction and / or heat convection, for the heat transfer from the heated coolant to the housing interior.
- the design according to the invention therefore allows waste heat, which is generated very quickly on system components when starting a fuel cell system, to be absorbed by means of the already existing and required cooling function and into the temperature. to forward the perimeter housing.
- This waste heat is available due to the system and can be made available very quickly for use in temperature control, in this case heating.
- the temperature control i.e. in particular the heating of the temperature control housing and its housing interior, provides a temperature control option which can essentially completely dispense with the external heat supply.
- the temperature control housing is understood in particular to mean an integral component which includes all components and their functions, such as in particular heat exchangers, separators, injectors, containers.
- the housing interior is then also formed integrally with all the other parts and components.
- Such a temperature control housing is preferably produced at least partially by 3D printing or by another manufacturing process.
- a condensate tank is arranged in the interior of the housing, in fluid-communicating connection with the separation device for receiving liquid water separated from the anode exhaust gas.
- this condensate tank is also arranged in the housing interior of the temperature control housing, so that the reduction in the risk of icing through the described temperature control option according to the invention can also be applied to the condensate tank.
- the temperature control option is also made available to the condensate tank itself during a cold start, in particular during a frost start, so that undesirable icing can also be avoided here with a high degree of probability.
- a drain valve for draining liquid water separated from the anode exhaust gas.
- a drain valve can be used in combination with a condensate tank according to the previous paragraph.
- a drain valve is also conceivable without a condensate tank.
- the drain valve can be arranged inside, but also outside of the housing interior in specific embodiment variants of the temperature control housing. The arrangement of the drain valve within the interior of the housing brings with it the same advantages of temperature control, so that undesirable icing in cold start or frost start situations can also be reduced for this component in the form of the drain valve.
- a partial section of the anode supply section is arranged in the interior of the housing in a temperature control housing according to the invention.
- the anode supply section is also guided through the housing interior of the temperature control housing. This means that the temperature control functionality of the part of the cooling circuit is also available for this part of the anode supply section.
- the anode supply section which is tempered here, can be a section that only contains externally supplied fuel.
- the part of the anode supply section within the housing interior can also be arranged after a mixing device with the recirculation gas, so that a mixing chamber for mixing fuel and recirculation gas to form a common mixed gas as anode supply gas can also be placed within the housing space.
- the temperature control option according to the invention is extended here to regular operation, so that preheating is provided externally.
- tem fuel can also be ensured as part of the temperature control functionality within a temperature control housing according to the invention. In the best case, this means that there is no need for a separate heat exchanger for preheating fuel. In such a case, the advantages of reducing installation space, reducing complexity and minimizing costs are further increased.
- the interior of the housing in a temperature control housing according to the invention is free of a heat exchanger.
- the heat exchanger is a device in which fluid flows actively and in a guided manner in heat exchange with other fluid.
- These can be, for example, plate heat exchangers or similar types of heat exchangers, as will be briefly explained later.
- the temperature control functionality according to the invention in the non-specific manner, namely in a way that the entire housing interior of the temperature control housing is heated, means that such specific heat exchangers can be dispensed with in this embodiment.
- a heat exchanger for heating recirculation gas and/or anode supply gas is arranged in the interior of the housing in a temperature control housing according to the invention.
- the temperature control functionality is sufficient to ensure the desired preheating of recirculation gas, fuel or mixed gas as anode supply gas. If this temperature control function is not sufficiently dimensioned, additional heat exchangers can be used to provide specific, stronger heating for the individual gas streams. Because these heat exchangers are now integrated into the interior of the housing, they no longer have to provide complete heating, but rather build on the basic temperature control using the temperature control housing.
- a temperature control housing there is at least one ejector device for the anode supply section in the housing interior. is at least partially arranged.
- Such an ejector device is preferably arranged completely or substantially completely within the housing interior.
- An ejector device can, for example, have a mixing chamber which can ensure mixing of fuel and recirculation gas.
- the mixed gas is then passed through the nozzle of the ejector device so that a pressure difference leads to a suction effect on the recirculation gas.
- the delivery of the mixed gas as anode supply gas to the anode section of the fuel cell stack can preferably be designed to be free of rotating components, such as fans.
- the housing wall has fluid lines which at least partially form the part of the cooling circuit in the housing interior. While in principle any form of heat transfer to the internal volume of the housing interior is sufficient to provide the temperature control functionality in the manner according to the invention, such cooling lines can allow a significantly more precise temperature control function.
- the cooling lines can, for example, be integrated into the housing wall like a network and, in particular, provide heat transfer functions of different strengths in different areas of the housing wall. For example, it is conceivable that such a very high number of cooling lines is provided in the area of the separation device in order to actually be able to make a disproportionately large amount of the waste heat conveyed within the coolant in the cooling circuit available to the separation device. Integrating the fluid lines into the housing wall reduces the space requirement even further and can in this way further strengthen the advantage of the improved installation space.
- the housing wall has at least one insulating section for thermal insulation of the housing interior from the surroundings of the temperature control housing.
- thermal insulation can be used, for example, as a thermal insulating layer be trained.
- an outer wall layer it serves to thermally insulate the housing wall from the outside, so that both a loss of heat in cold outside situations and also an ingress of heat in particularly hot environmental situations can be avoided. This means that temperature control is made even easier, as the independence from the ambient temperature increases.
- the part of the cooling circuit has control means, in particular in the form of at least one control valve, for controlling the fluid flow through the part of the cooling circuit in the housing interior to control the temperature control performance.
- control means in particular in the form of at least one control valve, for controlling the fluid flow through the part of the cooling circuit in the housing interior to control the temperature control performance.
- control valves can be used, which either qualitatively completely shut off or completely unlock the fluid flow through this part of the cooling circuit.
- Quantitative control for example by actually setting and regulating a volume flow of cooling fluid through this part of the cooling circuit, is also fundamentally conceivable.
- a fuel cell system which has a fuel cell stack with an anode section and a cathode section.
- the anode section is equipped with an anode supply section for supplying anode supply gas and an anode discharge section for discharging anode exhaust gas.
- the cathode section is equipped with a cathode supply section for supplying cathode supply gas and a cathode discharge section for discharging cathode exhaust gas.
- the fuel cell system has a cooling circuit for cooling system components of the fuel cell system.
- Such a fuel cell system is characterized in that a separating device for separating water from the anode exhaust gas is arranged in the anode discharge section within a temperature control housing according to the invention.
- a fuel cell system according to the invention therefore also brings with it the same advantages as have been explained in detail with reference to a temperature control housing according to the invention.
- a further subject of the present invention is a method for temperature control of a temperature control housing according to the present invention during a cold start of a fuel cell system according to the invention, comprising the following steps:
- a method according to the invention also brings with it the same advantages as have been explained in detail with reference to a temperature control housing according to the invention.
- FIG. 3 shows a further embodiment of a fuel cell system according to the invention
- Fig. 5 shows a further embodiment of a fuel cell system according to the invention.
- 1 shows a schematic representation of a fuel cell system 100, which is capable of producing electrical power from fuel and ambient air with the oxygen contained therein.
- a large number of fuel cells are arranged in a fuel cell stack 110, which can be schematically divided into an anode section 120 and a cathode section 130.
- Ambient air is sucked in here by a fan device and made available to the cathode section 130 as cathode supply gas KZG via a cathode supply section 132.
- a fuel not shown from the left, is supplied as anode feed gas AZG via the anode feed section 122 to the anode section 120.
- the resulting cathode exhaust gas KAG can be absorbed via the cathode discharge section 134, discharged and, for example, released into the environment.
- the anode exhaust gas AAG is absorbed here via the anode discharge section 124 and, in this embodiment, at least partially fed to recirculation.
- the separation of liquid water W is desired here.
- the anode exhaust gas AAG is fed to a separation device 30, which is able to separate liquid water W from the anode exhaust gas AAG and to drain it here via a drain valve 50.
- the dried anode exhaust gas AAG is output as recirculation gas RZG from the separation device 30 via the recirculation gas outlet 34 and fed to a mixing section in the anode supply section 122.
- the recirculation gas RZG is mixed with a fuel (not shown) to form a mixed gas, which in turn is supplied as anode supply gas AZG to the anode section 120 via the anode supply section 122.
- At least the separation device 30 with the recirculation gas outlet 34 and the anode exhaust gas inlet 32 is arranged within a housing interior 22 of a temperature control housing 10 and is therefore essentially enclosed by the housing wall 20.
- a defined temperature can be set within this temperature control housing 10, i.e. temperature control can take place.
- a section of a cooling circuit 140 is shown here. Not shown in more detail is the known part of this cooling circuit 140, which leads to the individual operating components of the fuel cell system 100, also not shown, in order to cool them by absorbing waste heat from such system components.
- the coolant of the cooling circuit 140 heated in this way is now guided into this section within the housing interior 22 of the temperature control housing 10 and can release at least part of this absorbed waste heat there. This leads to heating of the housing interior 10 and in this way all components within this housing interior 22. This leads to the advantages mentioned, in particular a targeted temperature control of the separating device 30 during a cold start or a frost start.
- FIG. 2 shows a further development of the embodiment of FIG. 1.
- the part of the cooling circuit 140 which is part of the housing interior 22, is now integrated into the housing wall 20 as a fluid line 24. This leads to greater compactness and at the same time even better heat distribution when controlling the temperature of the housing interior 22.
- a condensate tank 40 is provided here, which can absorb and store separated water W from the separating device 30.
- this condensate tank 40 of FIG. 2 is now combined with the drain valve 52 of FIG. Not shown in more detail, but in principle it is also possible to provide a so-called purge valve on the top of the separating device 30 in order to also be able to provide purge processes.
- the mixing device for mixing a recirculation gas RZG with a fuel is now also integrated into the housing interior 22.
- this temperature control and preheating option is so strong formed that a separate heat exchanger 60 can be completely dispensed with.
- FIG. 4 shows a variant which requires greater preheating than can be provided by the temperature control function of the temperature control housing 10. Therefore, a heat exchanger 60 is provided here in the anode supply section 122, integrated into the housing interior 22, which can preheat the supplied fuel before it is mixed with the recirculation gas RZG.
- Figure 5 shows a variant in which the isolation from the environment is increased.
- the temperature control housing 10 and the housing wall 20 are designed with an insulating section 26, which ensures thermal insulation from the environment.
- the introduction of heat in hot environmental situations and the loss of heat in cold environmental situations can be significantly reduced in this way.
- This increases the control options for the temperature control process itself.
- 5 also shows a variant in which the fluid flow through the cooling circuit 140 can be controlled.
- a total of three control means 80 are shown here in the form of control valves, which allow the volume flow of the coolant and thus the amount of heat introduced for the temperature control function to be controlled in a qualitative or even quantitative manner. In one case, a complete bypass is even possible, so that the temperature control function can not only be varied but also completely switched off by these control means 80.
- Figures 4 and 5 show the use of a so-called ejector device 70, which is partly arranged in the housing interior 22.
- This ejector device 70 serves to mix supplied fuel and recirculation gas RZG and pass them through an ejector nozzle.
- pressure differences arise, which lead to suction and thus active delivery of the recirculation gas RZG.
- This form of conveyance is preferred because no mechanically moved, especially rotated, components are required to convey the recirculation gas RZG.
