Disclosure of Invention
According to the invention, a delivery device for a fuel cell system is proposed, wherein the delivery device has a nozzle and a diffuser, and the diffuser can be displaced in the axial direction by means of an adjusting element arranged inside the delivery device. Advantageously, the diffuser is arranged in such a way that it opens or closes the first H2The flow inlet and at the same time the gap width of the annular gap implemented between the diffuser displaceable in the axial direction and the nozzle fixedly arranged in the conveying device are adjusted. This results in a throughflow cross section for the recirculated material to be conveyed by the conveying device proposed according to the invention and thus, if necessary, in the H 2The regulation of the recirculation effects a variation of the cross-section ratio between the annular gaps through which the propellant gas passes from the first H2The inflow port flows out. Cross section ratio ARezirkulat/ARingspaltAnd may vary over a wide range between 8 and 50. In the first H2The smaller the flow cross-section at the flow inlet is set, the larger the first H2The outflow speed of the propulsion gas medium flowing in from the inflow opening. Via a first H2The higher the outflow speed of the propellant gas medium flowing out of the inflow opening, the higher the delivery rate can be set by means of the delivery device proposed according to the invention.
The solution proposed according to the invention is as follows: the diffuser is received on a support site containing the adjustment element. The adjusting element can be embodied in a preferred manner as an electromagnet. An electrical connection of the electromagnet leads out of the conveying device, through which the electromagnet is energized.
An annular gap is formed between a nozzle which is fixedly received in the delivery device and a diffuser which is displaceable in the axial direction. First H2The inflow opening opens into the annular gap, and hydrogen passes through the first H2The inflow opening is filled with hydrogen, which serves as a gaseous propellant medium for another gaseous medium to be conveyed, in the present case in particular For H2Recycling the product.
The annular gap between the nozzle, which is arranged fixedly in the conveying device, and the diffuser, which is displaceable in the axial direction, is bounded on one side by a diffuser surface and on the other side by a nozzle surface. The diffuser is displaceable in the axial direction relative to a nozzle which is fixedly arranged in the conveying device, so that the annular gap width of the annular gap between the nozzle face and the diffuser face can be varied.
In a further embodiment of the solution proposed according to the invention, the diffuser, which can be actively displaced in the axial direction, is pretensioned in the axial direction by a spring. In the rest position, the spring presses the diffuser against a seat with which the diffuser closes the first H2An inflow port. The spring loading the diffuser is supported on one side on a press-in ring which is pressed into the pole of the delivery device. Depending on the axial position of the press-in ring pressed into the pole, the spring travel and the pretensioning of the spring in the rest position on the diffuser can be adjusted. In the non-actuated state of the actuating element, the diffuser closes the first H by means of a sealing element, which is designed, for example, as an elastomer sealing ring or the like2An inflow port. If the actuating element, which is in particular designed as an electromagnet, is actuated, the diffuser is displaced in the axial direction against the pretensioning force of a spring acting on the diffuser, so that the first H 2The inflow opening is released and, on the other hand, the gap width of the annular gap is adjusted simultaneously. The displacement path of the electromagnetic assembly lies in the axial direction in a range between 0 μm and 100 μm, preferably between 0 μm and 500 μm and particularly preferably between 0 μm and 300 μm. Depending on the current supply to the actuating element, the first H can be switched on2The gap width of the annular gap between the nozzle surface and the diffuser surface is changed when the flow enters the flow inlet. Thus being able to influence the flow velocity, gaseous H2Flows out of the annular gap at this flow speed and thus influences H2Is recycled.
A preferred possibility of use of the delivery device proposed according to the invention is its use in fuel cell systems.
The advantage associated with the solution according to the invention is that it is possible to reduce the cost by using the solution according to the inventionThe conveying device according to the invention achieves an active displacement of the diffuser via an adjusting element in the interior of the conveying device. Thus, the first H can be influenced2With inflow opening for H used as gaseous propellant2And thereby adjust H on the fuel cell system according to demand2And (4) recycling. Through the through-flow cross section Arezirkulat/ARingspaltIn particular for H2In the case of a constant throughflow cross section of the recirculated material, the outflow opening of the annular gap in the central flow channel is increased or decreased, as a result of which a flow from the first H occurs in the central throughflow cross section 2Gaseous propellant gas flowing out of the inlet, i.e. H2Is reduced or increased. In order to achieve a compact design of the transport device proposed according to the invention, the adjusting element, which is in particular designed as an electromagnet, is advantageously integrated into the bearing point for the diffuser. Electrical connections, i.e. coil connections, are guided through holes in the receiving part and the cover and on the poles out from both sides of the conveying device. The individual components of the conveying device, the poles, the nozzle and the bearing points of the diffuser formed in the nozzle for displacement in the axial direction can be screwed together, for example, in the longitudinal direction.

fig. 1 shows an embodiment variant of a delivery device according to the invention with an axially displaceable diffuser.
Detailed Description
From the illustration according to fig. 1, an embodiment variant of the conveying device according to the invention with an axially displaceable diffuser results.
A longitudinal section of the conveying device 8 proposed according to the invention, which is designed rotationally symmetrically with respect to its axis of symmetry, is taken from the illustration according to fig. 1. The conveying device comprises a pole 10 and a nozzle 12 which is fixedly mounted in the conveying device 8. The magnetic separator is designated by reference numeral 14. The conveying device 8 comprises a diffuser 16, which is substantially annular and is actuated by means of an actuating element 18, in particular embodied as a solenoid coil. An adjusting element 18 in the form of a solenoid is received in a bearing point 20 for the diffuser 16 of annular design.
As can be seen from the illustration according to fig. 1, the diffuser 16, which is of substantially annular design, is loaded in the axial direction by a spring 24. The spring 24 is supported on the press-in ring 22. The press-in ring 22 is pressed into the pole 10. Depending on the desired pretension to be applied to the diffuser 16 by the spring 24, the press-in ring 22 is fitted on the inner circumferential surface of the pole 10. In the rest position of the adjusting element 18, the spring 24 supported on the press-in ring 22 presses the diffuser against the nozzle 12. An elastomeric seal 26, preferably configured in the form of a ring, may be arranged on the seat formed between the nozzle 12 and the diffuser 16. First H due to the pretension applied to the diffuser 16 by the spring 242The inflow port 28 is closed. Is free of H2Can pass through the first H of closing2The inflow opening 28 reaches into the flow cross section of the conveyor device 8. From first H2H flowing out of the inflow opening 282As for gaseous recycling, especially H2Recycled gaseous propellant medium, said H2The recirculation is conveyed, for example, out of the fuel cell stack, for example, via a further, second inflow opening 36 in the central flow channel of the conveying device 8 proposed according to the invention.
The magnetic circuit 30 is composed of a pole 10, a nozzle 12 and a diffuser displaceable in the axial direction 42.
Except for first H2The nozzle 12, which is fixedly received in the conveying device 8, has a second H outside the inflow opening 282An inflow port 36. Via the second H2An inflow 36, into which the gaseous hydrogen flows into the central throughflow cross section of the conveying device 8. And via the first H2Gaseous H used as propulsion medium and flowing into the central flow channel of the conveying device 8 from the inflow opening 282Correspondingly conveys the recirculation flow, in particular H, flowing in via the second inflow 362Recycling the product. From first H2The inflow opening 28 flows into the conveying deviceH in the central flow cross section of the device 82Is determined to be from the second H2H of the inflow port 362The transport speed of the recyclate.
From the illustration according to fig. 1, the first H2 An inflow opening 28 extends through the nozzle 12 and opens out onto the elastomer seal 26 in the region of the seat. As already mentioned, in the rest position of the diffuser 16, the first H2The inflow opening 28 is closed by the pretension exerted by the spring 24. As soon as the actuating element 18, which is preferably designed as a solenoid, is actuated, the displaceable diffuser 16 is attracted from its rest position in the state in which the actuating element is energized again and the first H2The inlet opening 28 is released to the inlet portion in the central throughflow cross section of the conveying device 8 proposed according to the invention. The inlet region has a larger or smaller flow cross section in accordance with the current supply to the actuating element 18, which is in particular embodied as a solenoid. According to at first H 2The flow cross section at the inlet point of the inflow opening 28 is measured from the first H2The outflow speed of the gaseous propellant medium injected by the inflow opening 28 into the central throughflow cross section is adapted.
The active displacement of the diffuser 16 in the axial direction 42 is effected by the energization of an actuating element 18, preferably in the form of an electromagnetic coil, which is received in a sealing manner in the bearing point 20. If the actuating element 18 is energized, the diffuser 16 is attracted against the pretensioning force generated by the spring 24 and is at a first H2The seat on the end of the inflow opening 28 is opened. At the same time, depending on the degree of current flow of the actuating element 18, which is in particular designed as a solenoid, the first H is opened in this way2The flow inlet 28 such that the width 46 of the annular gap 44 is varied. The annular gap 44 between the nozzle 12, which is arranged fixedly in the conveying device 8 on the one hand, and the diffuser 16, which is actively displaceable in the axial direction 42 on the other hand, is widened or narrowed depending on the degree of energization of the adjusting element 18.
In the first H2When the inlet 28 is open, gas H2Through the annular gap 44 into the recirculated H2In the stream, the H2The flow is parallel to the axis of symmetry of the conveying device 8 proposed according to the invention52 flow through the delivery device and through a second H 2The inflow opening flows unimpeded into the conveying device. The annular gap 44 between the nozzle 12 and the displaceable diffuser 16 is bounded on the one hand by a nozzle face 50 of the nozzle 12 which is fixedly arranged in the conveying device 8 and on the other hand by a diffuser face 48 of the diffuser 16 which is displaceable in the axial direction 42. Due to the different inclinations of the diffuser surface 48 and the fixed nozzle surface 50, the annular gap 44 narrows in the direction of its inlet point corresponding to the axial position of the displaceable diffuser 16. When the actuating element 18 is not energized, a sealing element in the form of an elastomer seal 26 inserted into the displaceable diffuser 16 closes a first H2 An inflow port 28. The displaceable diffuser 16 thus has a sealing function, which means that in the first H2Preventing H acting as a gaseous propellant medium when the inflow 28 is closed2Inflow, i.e. first H2The inflow opening 28 is in this case closed.
In the embodiment variant of the transport device 8 proposed according to the invention shown in fig. 1, a first H2The inflow 28 has a horizontal section 40 and a vertical section 38. Thus, first H2The inflow opening 28 extends at right angles through the material of the nozzle 12 fixedly arranged in the conveying device 8. Advantageously in terms of production technology, the vertical section 38 and the horizontal section 40 can be produced as bores in the material of the nozzle 12 in a particularly simple manner. Corresponding to the selected hole diameter, through the first H2Gas state H of the inlet 282Mass flow through first H2The inflow port 28 is adaptively adjusted.
In the embodiment variant shown in FIG. 1, in the recirculated gaseous H2During the flow through the second inlet opening 36 of the nozzle 12 into the main flow cross section in the region of the axis of symmetry 52 of the conveying device 8, the actuating element 18, which is designed as a solenoid, can be actuated by passing it in the axial direction42 the displaceable diffuser 16 realizes a first H2Opening and closing of the inflow opening 28. At the first H of opening the conveying device 82After the inflow opening 28, the width 46 of the annular gap 44 can be changed by appropriate energization of the actuating element 18, preferably in the form of a solenoid, which is supported on the bearing point 20. This enables the incoming gaseous H to be influenced in a targeted manner, as required, in particular during partial load operation 2The flow velocity of (2). Depending on the gas state H at the inlet point of the annular gap 44 in the region of the axis of symmetry 52 of the conveying device 82Flow velocity of, recycled H2Is directed from the fuel cell stack into the second inlet 36 due to the jet pump action. Conversely, if the actuating element 18, which is preferably designed as a solenoid, is not energized, a first H is provided2The inflow opening 28 is closed because it is closed at the outflow point in the material of the nozzle 12 by a sealing element in the form of an elastomer seal 26 which performs a sealing function. The needle of the delivery device 8, which is designed as a jet pump, is designated by reference numeral 54.
