Definitions
- Humidifier fuel cell device with humidifier
- the invention relates to a humidifier with a plurality of humidifier modules clamped between end plates by means of tension rods and having a membrane permeable to water vapor, in which a flow field frame with a plurality of webs defining a flow field is arranged on each side of the membrane.
- the invention further relates to a fuel cell device and a motor vehicle.
- Humidifiers in general are used in order to be able to transfer the moisture to the drier medium in two gaseous media with a different moisture content.
- Such gas / gas humidifiers are used in particular in fuel cell devices in which air is compressed in the cathode circuit to supply the cathode spaces of the fuel cell stack with the oxygen contained therein, so that relatively warm and dry compressed air is present, the moisture of which is used for the use in the fuel cell stack for the membrane electrode assembly is insufficient.
- the dry air provided by the compressor for the fuel cell stack is humidified by being guided past the membrane which is permeable to water vapor and the other side of which is coated with the moist exhaust air from the fuel cell stack.
- liquid water accumulates in the fuel cell stack both on the anode side and on the cathode side, which has to be removed from the fuel cell stack.
- the humidifier, the water separator and the charge air cooler positioned after the compressor are large components that greatly increase the space required for one Contribute fuel cell device and limit the efficiency of the fuel cell device because of high thermal losses.
- DE 10 2016 113 740 A1 discloses a conditioning module which provides a combination of a heat exchanger and a humidifier with a small space requirement and at the same time a high possible throughput, in that in a cross section of the conditioning module a first cross-sectional area within a second cross-sectional area in a zy - Lindrike structure is arranged.
- WO 2017/102538 A1 describes a humidifier with an integrated water separator, which has a large number of separate separating elements on one side of the membrane in order to enable an optimized moisture exchange between exhaust gas and operating medium flows of a fuel cell.
- the invention has for its object to provide a humidifier of the type mentioned with an inexpensive structure. Another object of the invention is to provide an improved fuel cell device and a motor vehicle with increased efficiency.
- the humidifier according to the invention is distinguished by the simplicity of its construction, in which a component which has already been recognized as necessary, namely the tension rods, is used to perform a further function by simply modifying the construction of the tension rods.
- the tension rods are designed as hollow rods, there is the possibility of using them as coolant tubes for the passage of a cooling medium.
- the cooling medium can be used both for cooling the media located in the flow fields, in particular gases, if the cooling medium is cooler than the medium in the flow field.
- the coolant flowing through the hollow rods as coolant tubes can also be loaded with heat, so that heat transfer and thus energy supply is possible.
- the plurality of hollow bars are assigned common connections for the supply line and the discharge line of the cooling medium. It is also advantageous if at least the flow fields in the flow field frame are formed from a thermally conductive material, which contribute to an improved heat exchange. It also serves to increase the surface of the flow fields to increase the heat transfer area by means of structures which are selected from the group comprising ribs, fins and wings.
- the thermally conductive material is formed by a metal or a thermally conductive plastic with metallic fillers.
- the hollow rods are sealed off from the flow fields by means of seals, the seal being selected from a group which comprises O-rings, moisture-sensitive expansion seals, adhesive seals and joint material.
- the adhesive seals can be used in a simple manner in the manufacture of the humidifier, with an alternative or in addition also the possibility that a material with a high expansion during humidification is placed in the holes in the membrane and / or flow field frame receiving the tie rods that when the humidifier is used for the first time, the material swells and provides the sealing effect as an expansion seal.
- An improved fuel cell device with a fuel cell having a membrane electrode arrangement, the electrode spaces of which can be supplied with reactants via reactant supply lines and which has reactant exhaust gas lines, is provided in that a humidifier described above is switched into the flow path of at least one of the reactant supply lines and the associated reactant exhaust gas line is, preferably on the cathode side, so that the humidifier can be used to condition the cathode gas.
- the improved fuel cell device is used in a motor vehicle in that the coolant circuit of the air conditioning unit includes the flute rods of the humidifier, so that the gas originating from the compressor and flowing through the humidifier can be tempered. If water stores are provided in the humidifier, the stored water is additionally tempered with the coolant, so that it can evaporate more easily and thus contribute to the moistening of the fuel cell stack.

- FIG. 6 shows a schematic illustration of a fuel cell device connected to the coolant circuit of a motor vehicle.
- FIG. 1 shows the part of a fuel cell device 1 which is necessary to explain the invention, the fuel cell device 1 comprising a device for regulating the moisture of a plurality of fuel cells combined in a fuel cell stack 2.
- Each of the fuel cells comprises an anode, a cathode and a proton-conductive membrane separating the anode from the cathode.
- the membrane is formed from an ionomer, preferably a sulfonated tetrafluoroethylene polymer (PTFE) or a polymer of perfluorinated sulfonic acid (PFSA).
- PTFE sulfonated tetrafluoroethylene polymer
- PFSA perfluorinated sulfonic acid
- the membrane can be formed as a flydrocarbon membrane.
- a catalyst can additionally be admixed to the anodes and / or the cathodes, the membrane preferably having on its first side and / or on its second side a catalyst layer composed of a noble metal or a mixture comprising noble metals such as platinum, palladium, ruthenium or The same are coated, which serve as reaction accelerators in the reaction of the respective fuel cell.
- the anode can be supplied with fuel (eg hydrogen) via an anode compartment.
- fuel eg hydrogen
- anode compartment e.g hydrogen
- PEM fuel cell polymer electrolyte membrane fuel cell
- fuel or fuel molecules are in at the anode Protons and electrons split.
- the PEM lets the protons through, but is impermeable to the electrons.
- the reaction takes place at the anode: 2H 2 -> 4H + + 4e (oxidation / electron donation).
- the electrons are conducted via an external circuit to the cathode or to an energy store.
- the cathode gas eg oxygen or oxygen-containing air
- the cathode gas can be supplied to the cathode via a cathode chamber, so that the following reaction takes place on the cathode side: 0 2 + 4H + + 4e -> 2H 2 0 (reduction / electron absorption) ,
- the cathode gas is humidified before it is fed to the fuel cell in order to bring about moisture saturation of the PEM.
- cathode gas Since several fuel cells are combined in the fuel cell stack 2, a sufficiently large amount of cathode gas must be made available, so that a large cathode gas mass flow is provided by a compressor 3, the temperature of which increases strongly as a result of the compression of the cathode gas elevated.
- the conditioning of the cathode gas that is to say its setting with regard to the parameters desired in the fuel cell stack 2, takes place in a charge air cooler and in a humidifier 4.
- the humidifier 4 shown as an exemplary embodiment in FIG. 3 has two end plates 5, between which a plurality of humidifier modules 6 are arranged, the humidifier modules 6 being clamped between the end plates 5 by tension rods 7.
- the assignment of the media connections 8 for the supply and discharge of the two media to one of the end plates 5 has been made, the two in the case of a fuel cell device 1 Media only differ in terms of their moisture content, but there is usually air in material.
- the media connections 8 for one of the media are arranged jointly on one of the end plates 5 or separately on the two end plates 5, and that the media connections 8 for the other medium together on the same or the other end plate 5 as the media connections 8 for the first medium or separately on the two end plates 5 with inverted assignment of the media connections 8 for the supply and discharge are arranged relative to the first medium, that is to say the humidifier modules 6 arranged in series with respect to a medium U-or Z- can be flowed through in a form, while a countercurrent or cross-countercurrent is also possible when considering the two media.
- FIG. 2 shows the structure of an individual humidifier module 6.
- a flow field frame 10 with a plurality of webs 11 defining a flow field is arranged on each side of the membrane 9, and a seal 12 is arranged between each of the flow field frames 10 and the membrane 9, so that a sequence of flow channels for the unit of a humidifier module Field frame 10 - seal 12 - membrane 9 - seal 12 - flow field frame 10 results.
- the flow field frame 10 and the webs 11 have the same height extension, while in the flow field frame 10 on both sides of the webs 11 there is a connector 13 which positions the webs 11 and has a lower height extension than the webs 11, which is on the Inside of the flow field frame 10 is connected in a corner with two adjoining legs.
- This connector 13 thus provides a collector 14 in the corner for the medium, which is distributed between the webs 11 due to the small height extension of the connector 13 from this collector 14 to generate the flow field. Since the webs 11 have the same height as the flow field frame 10, an exchange of the medium between the webs 11 is not possible and there is a uniform distribution of the medium in the flow field over the entire surface of the membrane 9. Because the webs 11 continue to have the same height as that Flow field frame 10, the webs 11 also support the membrane 9 and increase the mechanical stability of the entire humidifier module 6.
- the seals 12 are designed as a sealing frame 15 with two opposing cross connectors 16, which are connected at the inside of the sealing frame 15 via corners with two adjoining legs, with the connectors 13 and the cross connectors 16 on one side of the membrane 9 complementary corners are assigned, and wherein the membrane 9 has the shape of a hexagon, the edges of which are assigned to the connectors 13, the cross-connectors 16 and the frames 10, 15.
- FIG. 2 thus shows that in the lower flow field frame 10 shown in FIG. 2, the supply of the moist medium can take place in the right corner, which is passed between the webs 11 via the connector 13 and the flow field and the flow through the opposite corner River field frame 10 can leave again.
- the course of the webs 11 is at an angle of 90 degrees with respect to the course of the webs 11 in the lower river field frame
- the connector 13 in the upper flow field frame 10 in turn creates the possibility of supplying the dry medium between the webs 11 and removing the dry medium between the webs
- the humidifier module 6 as a unit can overall be sealed off from the outside in the area of the webs 11; alternatively, there is also the possibility that two of the humidifier modules 6 are combined to form a pair of modules and that the flow field frames on the mutually facing side 10 are arranged for the identical medium, so that identically manufactured humidifier modules 6 can be arranged in series without an exchange from the flow field frame 10 for the moist medium into the adjacent flow field frame 10 for the dry medium.
- the seal 12 can be designed as an insert seal for which materials such as PTFE or EPDM are suitable.
- materials such as PTFE or EPDM are suitable.
- the membrane 9 the use of polymer membranes, such as sulfonated membranes, is conceivable; cotton membranes are also suitable.
- the humidifier consists of a plurality of humidifier modules 6 braced by tension rods 7, there is the advantageous possibility that the tension rods 7 are designed as flute rods 17 forming coolant tubes for the passage of a cooling medium which is provided by common connections for the feed line and the discharge through the flute rods 17 is performed.
- the flow fields are to be made of a thermally conductive material, in particular a metal such as aluminum or steel. It is also conceivable to use a plastic with high thermal conductivity, it being possible for the high thermal conductivity of the plastic to be provided via metallic fillers.
- FIG. 4 shows that, deviating from the illustration in FIG. 3, it is also possible to arrange the tension rods 7 inside the humidifier 4, the positioning of the hollow rods 17 shown in FIG. 4 causing an early gas preheating with the result of better water absorption ,
- FIG. 5 indicates that the hollow rods 17 are sealed off from the flow field frame 10 and the membrane 9 by means of seals 18, a sealing effect being able to be achieved by means of adhesive points or in a simple manner by means of O-rings.
- the fuel cell device 1 shown in FIG. 5 presupposes its use in a motor vehicle, the coolant circuit of the air conditioner being connected to the hollow rods 17 of the humidifier 4 in order to temper the gas flowing through the humidifier 4 and by using the Waste heat from the air conditioner to improve the efficiency of the fuel cell device 1 and thus of the motor vehicle as a whole. If water reservoirs are arranged in the humidifier 4, there is the additional possibility of tempering the stored water with the coolant and thus evaporating it more easily and contributing to the humidification of the fuel cell stack 2.
