Description

Fuel cell evaluation system, tilt test device, fuel cell evaluation method, and program for fuel cell evaluation system

[0001] The present invention relates to a fuel cell evaluation system for evaluating a fuel cell, a tilt test device, a fuel cell evaluation method, and a program for the fuel cell evaluation system.

[0002] Conventionally, fuel cell evaluation systems for evaluating the power generation performance of fuel cells mounted on vehicles have evaluated the fuel cells while they are fixed (see, for example, Patent Document 1). However, in actual use cases where a fuel cell is mounted on a moving object such as a vehicle, the fuel cell will tilt depending on the moving state of the moving object. In this case, hydrogen and oxygen react chemically to generate water during power generation in the fuel cell. However, if the fuel cell is tilted, the water (also known as condensed water) that should be discharged from the outlet may flow back, affecting the power generation performance of the fuel cell. Conventionally, no method has been devised for evaluating power generation performance that takes into account the effect of condensed water caused by fuel cell tilt.

[0003] JP 2010-021096 A

[0004] The present invention has been made in view of the above-mentioned problems, and has as its main object to make it possible to evaluate a fuel cell taking into consideration the influence of condensed water generated by power generation.

[0005] In other words, the fuel cell evaluation system of the present invention is for evaluating a fuel cell to be mounted on a moving body or a test specimen that is a part thereof, and is characterized by comprising a hydrogen gas supply line that supplies hydrogen gas to the test specimen, a discharge unit that controls the discharge load of the test specimen, and a tilt test device that has a mounting base on which the test specimen is mounted and tilts the mounting base to change the posture of the test specimen in accordance with the moving state of the moving body.

[0006] With this configuration, the tilt test device can tilt the fuel cell specimen by changing its posture to match the moving state of the moving body (i.e., simulating the state of being mounted on the moving body), making it possible to evaluate the fuel cell while taking into account the effects of condensed water generated by power generation, such as backflow of condensed water generated by power generation without being properly drained. Note that the tilt test device may reproduce a predetermined tilt or a tilt arbitrarily set by the user in order to reproduce the moving state of the moving body.

[0007] Specific examples of the moving state include one or more states selected from a state in which the moving body is accelerating, a state in which it is decelerating, a state in which it is moving at a constant speed, a state in which it is stopped, or a state in which it is moving on an inclined surface.

[0008] In addition, it is preferable that the discharge unit of the fuel cell evaluation system changes the discharge load of the test specimen in accordance with the moving state of the mobile body, and the hydrogen gas supply line changes the amount of hydrogen gas supplied to the test specimen in accordance with the moving state of the mobile body. In this way, it is possible to more accurately simulate the state in which a fuel cell is mounted on a mobile body, and to more accurately evaluate power generation performance, etc.

[0009] Furthermore, in the fuel cell evaluation system, it is preferable that the hydrogen gas supply line is arranged to pass near a fulcrum portion of the tilt test device that serves as a fulcrum for the tilt of the mounting table, and that the portion of the piping that makes up the line that passes near the fulcrum portion is made of a pipe made of an elastic material. In this way, by arranging the hydrogen gas supply line so that it passes near the fulcrum portion that serves as the center of rotational motion of the mounting table in the tilt test device, i.e., near a portion that undergoes little displacement when the mounting table tilts, it is possible to reduce movement of the hydrogen gas supply line when the mounting table moves, thereby reducing fluctuations in the amount of hydrogen gas supplied to the fuel cell and enabling more accurate evaluation of power generation performance, etc.

[0010] In a specific embodiment of the fuel cell evaluation system, the system further includes a discharge line connected to the discharge port of the test specimen and discharging condensed water generated by power generation to the outside, the discharge line being arranged to pass near a fulcrum portion that serves as a fulcrum for tilting the mounting table in the tilt test device, and the portion of the piping that constitutes the line that passes near the fulcrum portion is preferably constructed using a pipe made of an elastic material. In this way, by arranging the discharge line so as to pass near the fulcrum portion of the tilt test device, which has little displacement even when the mounting table tilts, and further constructing the portion that passes near the fulcrum portion using a piping made of an elastic material, it is possible to reduce movement of the discharge line when the mounting table moves, and to more accurately evaluate power generation performance, etc.

[0011] A specific embodiment of the fuel cell evaluation system is one further comprising a test result storage unit that stores the amount of hydrogen gas supplied to the test specimen, the amount of power generated by the test specimen, and the posture of the test specimen in association with each other.

[0012] Furthermore, it is preferable that the fuel cell evaluation system further includes a simulation device that simulates the moving state of the moving body using a moving environment model that models the moving environment of the moving body, a driving behavior model that models the driving behavior, and / or a moving body model that models the moving body, and the tilt test device tilts the mounting base so as to reproduce the moving state of the moving body simulated by the simulation device. In this way, the tilt test device can realistically reproduce a usage situation in which a fuel cell is actually mounted on a moving body, thereby enabling more accurate evaluation of the fuel cell that takes into account the effects of condensed water generated during power generation.

[0013] The tilt test device of the present invention is a tilt test device for testing a test specimen that is a fuel cell or part thereof to be mounted on a moving body, and is characterized by comprising a mounting platform on which the test specimen is mounted, and an attitude control unit that tilts the mounting platform so as to change the attitude of the test specimen in accordance with the moving state of the moving body.

[0014] The fuel cell evaluation method of the present invention is a method for evaluating a fuel cell to be mounted on a moving body or a test specimen that is a part thereof, and is characterized in that hydrogen gas is supplied to the test specimen, the discharge load of the test specimen is controlled, the test specimen is mounted on a mounting base, and the mounting base is tilted so as to change the posture of the test specimen in accordance with the moving state of the moving body.

[0015] The program for a fuel cell evaluation system of the present invention is for evaluating a fuel cell to be mounted on a moving body or a test specimen that is a part thereof, and is a program for a fuel cell evaluation system that includes a hydrogen gas supply line that supplies hydrogen gas to the test specimen, a discharge unit that controls the discharge load of the test specimen, and a tilt test device that has a mounting base on which the test specimen is mounted, and is characterized in that it causes a computer to function as an attitude control unit that tilts the mounting base so as to change the attitude of the test specimen in accordance with the moving state of the moving body.

[0016] Such a tilt testing device, fuel cell evaluation method, and program for a fuel cell evaluation system can achieve the same effects as the fuel cell evaluation system of the present invention.

[0017] According to the present invention configured in this manner, by changing the attitude of the fuel cell in accordance with the state of movement of the mobile body, it is possible to evaluate the fuel cell while taking into account the effects of condensed water generated by power generation.

[0018] The present invention relates to a fuel cell evaluation system and a control device for evaluating a fuel cell in accordance with an embodiment of the present invention.

[0019] A fuel cell evaluation system 100 according to one embodiment of the present invention will be described below with reference to the drawings.

[0020] The fuel cell evaluation system 100 of this embodiment is for conducting evaluation tests in a test room to evaluate the performance of a fuel cell to be mounted on a vehicle, which is a moving body. More specifically, this fuel cell evaluation system 100 tilts a fuel cell or a specimen S, which is a part of the fuel cell, in accordance with the moving state of the vehicle (specifically, the running state), thereby simulating the state in which the fuel cell is mounted on a vehicle and conducting an evaluation test of the cell performance.

[0021] The fuel cell S under test includes, for example, a fuel cell stack formed by stacking multiple unit cells each including a solid electrolyte, an air electrode (cathode), and a fuel electrode (anode). The housing housing the fuel cell stack in this test includes a hydrogen inlet for introducing hydrogen gas, which serves as fuel, into the fuel electrode, an oxygen inlet for introducing oxygen-containing gas (e.g., air) into the air electrode, and an outlet for discharging water (condensed water) generated by power generation. The fuel cell S is not limited to a fuel cell stack, but may also be a unit cell. In other words, the test specimen may be a fuel cell S or a part thereof. The fuel cell S may also be a fuel cell system including a fuel cell stack and its auxiliary components. Examples of auxiliary components include, but are not limited to, a hydrogen gas pump and valve, an air pump and valve, a compressor, an intercooler, a humidifier, a radiator, and / or a control system ECU.

[0022] Specifically, as shown in FIG. 1, this fuel cell evaluation system 100 comprises a power generating gas supply system 1 that supplies power generating gas to the test specimen, a discharge unit 2 that controls the discharge load of the test specimen, a tilt test device 4 that tilts the test specimen in accordance with the vehicle's running state, and a control device 5.

[0023] The power generation gas supply system 1 includes a hydrogen gas supply line 11 that supplies hydrogen gas to the anode of the test specimen. The upstream end of this hydrogen gas supply line 11 is connected to a hydrogen gas source such as a gas cylinder, and the downstream end is connected to a hydrogen inlet.

[0024] The power generation gas supply system 1 of this embodiment further includes an oxygen-containing gas supply line 12 that supplies an oxygen-containing gas (specifically, air) to the cathode of the test specimen. The upstream end of the oxygen-containing gas supply line 12 is connected to an oxygen-containing gas source such as a gas cylinder, and the downstream end is connected to an oxygen inlet.

[0025] The hydrogen gas supply line 11 and the oxygen gas supply line are each provided with a flow control device 13 that controls the flow rate of the gas flowing through each line. The flow control device 13 includes, for example, a mass flow controller or a flow control valve, and is configured to adjust the gas flowing through the line to a predetermined flow rate in response to a control signal output from the control device 5.

[0026] The power generation gas supply system 1 of this embodiment may further include a humidification mechanism (not shown) that humidifies the hydrogen gas or oxygen-containing gas supplied to the specimen. This humidification mechanism may be of any type, such as a bubbler type, an injection type, a shower type, or a divided flow type.

[0027] The fuel cell evaluation system 100 of this embodiment further includes a discharge line 3 for discharging condensed water generated by the power generation of the test specimen to the outside. The upstream end of this discharge line 3 is connected to the discharge port of the test specimen, and the downstream end is connected to a discharge tank, a water drain, or the like.

[0028] The discharge unit 2 controls the discharge load of the test specimen and has, for example, an electronic load device including a constant current control circuit. This electronic load device functions as a load that consumes the electrical energy generated by the test specimen. Controlling the discharge load of the test specimen with the discharge unit 2 enables performance evaluation simulating a usage state in which a load is connected to the test specimen.

[0029] The tilt test device 4 is a device (a so-called tilt bench) that can tilt a mounted test specimen at any angle. The tilt test device 4 can simulate the effects of the gradient and inclination of an actual road and / or the acceleration during vehicle travel (acceleration or deceleration). The tilt test device 4 includes a mounting table 41 on which the test specimen is mounted, support legs 42 that rotatably (tiltably) support the mounting table 41, and a drive mechanism (not shown) that rotates the mounting table 41.

[0030] As shown in FIG. 1 , the tilt test device 4 has longitudinal and lateral directions set to correspond to the longitudinal and lateral directions of the vehicle. The tilt test device 4 has a first rotation axis 4x parallel to the lateral direction and a second rotation axis 4y parallel to the longitudinal direction, and the mount 41 is configured to be able to rotate independently in the longitudinal and lateral directions about the rotation axes 4x and 4y. More specifically, the mount 41 can be tilted at a predetermined angle (e.g., −60° to +60°) relative to the longitudinal direction by rotating about the first rotation axis 4x, and can be tilted at a predetermined angle (e.g., −60° to +60°) relative to the lateral direction by rotating about the second rotation axis 4y.

[0031] At least one (here, all) of the hydrogen gas supply line 11, the oxygen-containing gas supply line 12, and the discharge line 3 is arranged to pass near a fulcrum 4f, which serves as a fulcrum for tilting the mounting table 41 (i.e., the center of rotational motion) in the tilt test apparatus 4. More specifically, at least one (here, all) of the hydrogen gas supply line 11, the oxygen-containing gas supply line 12, and the discharge line 3 is arranged to pass near at least one (here, both) of the first rotation axis 4x and the second rotation axis 4y set in the tilt test apparatus 4. The vicinity of the fulcrum 4f refers to a range within a predetermined range from the center of rotational motion where there is little movement in the front-to-back and / or left-to-right directions. The predetermined range is, for example, a range of a radius of 1.5 meters, 1 meter, or 0.5 meters from the center of rotation.

[0032] In this embodiment, one or both of the hydrogen gas supply line 11 and the oxygen-containing gas supply line 12 may be configured using flexible piping such as a flexible gas hose, at least for the piping that passes near the fulcrum 4f. Similarly, the discharge line 3 may be configured using piping that passes near the fulcrum 4f, at least for the piping that passes near the fulcrum 4f, made of a flexible and stretchable material. Furthermore, the hydrogen gas supply line 11, the oxygen-containing gas supply line 12, and the discharge line 3 may be configured using any type of piping, and may be configured using flexible or inflexible piping, at least for the piping that passes near the fulcrum 4f.

[0033] The control device 5 is used to control the attitude of the fuel cell S under test. Specifically, the control device 5 is a dedicated or general-purpose computer equipped with a CPU, internal memory, an input / output interface, an A / D converter, etc., and performs at least the function of an attitude control unit 54 as shown in FIG. 2 by the CPU and peripheral devices working together based on a predetermined program stored in the internal memory.

[0034] The attitude control unit 54 controls the attitude of the fuel cell S by outputting a control signal to the drive mechanism of the tilt test device 4 to control the rotational operation of the mounting base 41. Specifically, the attitude control unit 54 outputs a control signal including information regarding the tilt angle in each of the forward / backward and left / right directions to the drive mechanism to rotate the mounting base 41. This allows the fuel cell S to be tilted in accordance with the running state of the vehicle (specifically, the attitude of the vehicle while running). The attitude control unit 54 may be provided in the tilt test device 4.

[0035] In addition, the control device 5 of this embodiment may control the power generation operation of the fuel cell S, and may be configured to further perform the functions of a power generation control unit 51, a discharge control unit 52, an electrical measurement unit 53 and / or a test management unit 55.

[0036] The power generation control unit 51 controls the power generation gas supply system 1 to control the power generation operation of the test specimen fuel cell S. Specifically, the power generation control unit 51 sends control signals to the flow rate control devices 13 provided on the hydrogen gas supply line 11 and / or oxygen gas supply line to control the flow rate of the power generation gas (hydrogen gas and / or oxygen-containing gas) supplied to the air electrode and / or fuel electrode of the fuel cell S, thereby controlling the amount of power generated by the fuel cell S.

[0037] The discharge control unit 52 transmits a control signal to the electronic load device provided in the discharge unit 2 to control the load applied to the fuel cell S.

[0038] The electrical measurement unit 53 acquires measurement signals from an electrical measurement device such as an impedance analyzer or cell voltage monitor (not shown) connected to the fuel cell S, and measures the electrical characteristics of the fuel cell S, such as the power generation amount, resistance, current, or voltage.

[0039] The test management unit 55 controls the functions of each unit of the control device 5 and manages the evaluation test. The test management unit 55 may also manage the schedule of the evaluation test. Specifically, the test management unit 55 stores an arbitrary test schedule set by an operator. This test schedule includes the timing of the operations of the power generation control unit 51, the discharge control unit 52, the electricity measurement unit 53, and the attitude control unit 54, the control variables of the power generation control unit 51 (e.g., the supply amount of hydrogen gas and oxygen-containing gas), the control variables of the discharge control unit 52 (e.g., the magnitude of the load applied to the fuel cell S), the running state of the vehicle, and the control variables of the attitude control unit 54 (e.g., the tilt angle of the mounting base 41). In other words, the test management unit 55 also functions as a memory unit that stores the running state of the vehicle and each control variable corresponding to that running state. In the fuel cell evaluation system 100 of this embodiment, the test schedule is set so that the attitude (tilt angle) of the fuel cell S is changed in various ways, the supply amount of power-generating gas and the load amount of the fuel cell S are changed at each changed attitude, and the power generation amount of the fuel cell S is measured under various conditions. Information regarding the attitude of the fuel cell S, information regarding the supply amount of power generation gas (specifically, hydrogen gas and oxygen-containing gas) in each attitude, and information regarding the amount of power generated by the fuel cell S in each attitude are stored in association with each other in the test result storage unit 56. The evaluation test may be performed without varying the attitude, while keeping the fuel cell S fixed at a predetermined tilt angle.

[0040] The function of the attitude control unit 54 and the functions of the power generation control unit 51, the discharge control unit 52, the electricity measurement unit 53, and the test management unit 55 may be performed by one control device 5, or may be performed by multiple separate control devices 5. Furthermore, the functions of the attitude control unit 54, the power generation control unit 51, the discharge control unit 52, the electricity measurement unit 53, and the test management unit 55 may each be performed by a different device 5.

[0041] According to the testing system of this embodiment configured as described above, the tilt test device 4 can tilt the fuel cell S under test by changing its posture to simulate the running state of a vehicle, making it possible to evaluate the fuel cell while taking into account the effects of condensed water generated by power generation, such as backflow of condensed water generated by power generation without being properly drained. Furthermore, since the hydrogen gas supply line 11, oxygen gas supply line, or discharge line 3 is arranged to pass near the tilt fulcrum 4f of the tilt of the mounting base 41 in the tilt test device 4, movement of each line when the mounting base 41 moves can be reduced, allowing for more accurate evaluation of power generation performance, etc.

[0042] It should be noted that the present invention is not limited to the above-described embodiment. For example, the fuel cell evaluation system 100 may reproduce a predetermined inclination or an inclination arbitrarily set by the user in order to reproduce the moving state of a moving object.

[0043] 3, the fuel cell evaluation system 100 of another embodiment may further include a simulation device 6 that simulates the traveling state of a vehicle traveling on a road. In this case, the control device 5 may operate the power generation control unit 51, the discharge control unit 52, and the attitude control unit 54 so as to reproduce the traveling state of the vehicle simulated by the simulation device 6. The following describes an embodiment in which the simulation device 6 is included.

[0044] This simulation device 6 simulates vehicle road driving using a moving environment model that models a moving environment (specifically, a driving environment), a driving behavior model (driver model) that models a driving behavior, and a vehicle model that models an actual vehicle, and is a computer that includes a CPU, an internal memory, an input / output interface, input means such as a keyboard, output means such as a display, communication means, etc. As shown in Fig. 4, the simulation device 6 functions as a model data storage unit 61 that stores each model, and a simulation unit 62 that simulates the driving state of the vehicle based on each stored model.

[0045] The travel environment model is a model that quantifies, for example, the travel route, the road surface resistance of the travel route, signs, temperature, humidity, the altitude of the travel route, or the degree of congestion (traffic volume) of the travel route.

[0046] The driving behavior model is a model that quantifies, for example, Dynamics (amount of work), Energy Efficiency, or Nervousness.

[0047] The vehicle model is a model of vehicle information such as the type of actual vehicle (truck, passenger car, etc.), weight, transmission type (AT, CVT, etc.), tire diameter, gear ratio, engine characteristics (throttle opening, relationship between rotation speed and output torque, etc.), ECU control characteristics (relation between accelerator opening and throttle opening, etc.), TCU control characteristics (conditions for changing the gear ratio and the timing thereof, etc.), or BCU control characteristics (distribution of braking force to each wheel, etc.). Each of these models is stored in advance in the model data storage unit 61.

[0048] The simulation unit 62 simulates the driving conditions of a vehicle driving along a predetermined driving route using some or all of the travel environment model, some or all of the driving behavior model, and some or all of the vehicle model stored in the model data storage unit 61, and transmits driving condition data indicating the simulated driving conditions to the test management unit 55. The test management unit 55 then operates the power generation control unit 51, the discharge control unit 52, and the attitude control unit 54 based on the driving condition data generated by the simulation unit 62 so as to simulate the driving conditions of the vehicle indicated by the driving condition data. Note that, for example, some or all of the vehicle information indicated by the vehicle model may be realized by incorporating parts (actual devices) that constitute a vehicle into the fuel cell evaluation system 100.

[0049] Furthermore, although the fuel cell evaluation system 100 of the above embodiment includes an oxygen gas supply line connected to the oxygen inlet of the fuel cell S, this is not limiting. In other embodiments, the fuel cell evaluation system 100 does not include an oxygen gas supply line, as shown in Figure 3, and the fuel cell S may directly take in ambient air through the oxygen inlet.

[0050] In the fuel cell evaluation system 100 of the above embodiment, the fuel cell S under test does not have a discharge tank, and the generated condensed water is stored in an externally installed discharge tank via the discharge line 3, but this is not limited to this. In other embodiments, the fuel cell S under test may have the discharge line 3 and the discharge tank integrated into the housing.

[0051] Furthermore, although the tilt test device 4 in the above embodiment includes two rotation axes 4x and 4y, and the mounting base 41 can be tilted independently in the front-rear direction and the left-right direction, this is not limiting. In other embodiments, the tilt test device 4 may include only either the first rotation axis 4x or the second rotation axis 4y, and may be configured to tilt the mounting base 41 only in either the front-rear direction or the left-right direction.

[0052] In another embodiment, the control device 5 may further function as an evaluation unit that evaluates the effect of condensed water generated by power generation on the power generation performance of the fuel cell S. The evaluation unit may be configured, for example, to refer to information stored in the test result storage unit 56 and evaluate the effect of condensed water generated by power generation on the power generation performance of the fuel cell S based on the attitude of the fuel cell S, the amount of power generation gas (specifically, hydrogen gas) supplied in each attitude, and the amount of power generated by the fuel cell S in each attitude.

[0053] In another embodiment, the control device 5 may further function as a result output unit that outputs the test results stored in the test result storage unit 56 to a display device such as a display or a report or the like.

[0054] In other embodiments, some or all of the functions of the power generation control unit 51, the discharge control unit 52, the electrical measurement unit 53, the attitude control unit 54, and the test management unit 55 may not be performed by the same computer, but may be performed by separate computers.

[0055] Furthermore, while the fuel cell evaluation system 100 of the above embodiment is for evaluating a fuel cell to be mounted on a vehicle, this is not limited thereto. The fuel cell evaluation system 100 of other embodiments may be for evaluating a fuel cell to be mounted on another moving body, such as an aircraft, a train, or a ship. For example, the tilt test device 4 may be configured to tilt the mounting base 41 so as to change the attitude of the specimen S in accordance with the navigation state of an aircraft, the navigation state of a ship, or the running state of a railway vehicle. Here, the "moving state" refers to the running state of the moving body if the moving body is a vehicle (a concept that includes automobiles, motorcycles, trains, etc.), and refers to the navigation state if the moving body is an aircraft, a ship, etc.

[0056] In another embodiment, the fuel cell evaluation system 100 may further include a thermostatic chamber capable of adjusting the internal temperature. In this case, the specimen S (single fuel cell cell, fuel cell stack, or fuel cell system) and the tilt test device 4 may be placed inside the thermostatic chamber.

[0057] Furthermore, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit of the present invention.

[0058] According to the present invention described above, it is possible to evaluate a fuel cell taking into consideration the influence of condensed water generated by power generation.
