Description

  The present invention relates to a filter specification determination device for a fuel cell system.

  Heretofore, as a fuel cell system of this type, one having a filter for removing impurities in the air supplied to the fuel cell, has been proposed which determines the life of the filter. For example, the fuel cell system of Patent Document 1 is mounted on a fuel cell vehicle, and is a filter based on information on the impurity concentration of the position where the host vehicle is traveling and information on the traveling environment such as the average speed of the host vehicle. The amount of adsorption of impurities to be adsorbed is calculated, and the life of the filter is determined from the total amount of adsorption obtained by integrating the calculated amount of adsorption.

JP 2004-152669 A

  As described above, the fuel cell system mounted on the vehicle can be moved to a maintenance factory or the like, so that it is easy to replace the filter that has reached the end of its life. On the other hand, in the stationary type fuel cell system, the replacement of the filter is a business trip, resulting in an increase in cost. In addition, it is conceivable to use a filter with a long life and high removal ability to eliminate the work of replacing the filter or to reduce the frequency thereof.

  The main object of the present invention is to select an appropriate filter according to the area in which the stationary fuel cell system is installed.

  The present invention adopts the following means in order to achieve the above-mentioned main objects.

  The filter specification determination device of the fuel cell system according to the present invention includes a fuel cell that generates electric power based on fuel gas and air, and can attach a filter that removes impurities in air to the air supply path to the fuel cell. A filter specification determination device for a fuel cell system of a type, wherein impurity concentration acquisition means for acquiring the impurity concentration in air in the area where the fuel cell system is installed from the information on the impurity concentration in air according to area; The gist of the present invention is provided with a determination means for determining the specification of the filter based on the impurity concentration acquired by the impurity concentration acquisition means, and an output means for outputting the determination content by the determination means.

  In the filter specification determination apparatus of the fuel cell system of the present invention, the impurity concentration in the air in the area where the fuel cell system is installed is obtained from the information on the impurity concentration in the air according to the area, and the air supply path is obtained based on the impurity concentration. Determine the specifications of the filter attached to and output the contents of the determination. For this reason, according to the impurity concentration in the area where the fuel cell system is stationary, it is possible to determine the filter of the appropriate specification. Therefore, it is possible to properly exert the ability of the fuel cell system and optimize the filter life and reduce the cost of the filter.

  In the filter specification determination apparatus of the fuel cell system according to the present invention, the determination means is a specification of the filter, which physically removes impurities in the air without chemical reaction, or a chemical reaction of impurities in the air. Any of the removable chemical filters can be determined, and the physical filter is determined when the impurity concentration is lower than a predetermined concentration, and the chemical filter is determined when the impurity concentration exceeds the predetermined concentration. It is also good. In this way, it is possible to prevent the attachment of a physical filter which is likely to run out of removal ability in an area where the impurity concentration exceeds a predetermined concentration, and to prevent the removal ability from being excessive in an area where the impurity concentration is lower than a predetermined concentration. It is possible to prevent the installation of That is, it is possible to select an appropriate filter that prevents excess or deficiency of the removal ability by simple processing.

  In the filter specification determination apparatus for a fuel cell system according to the present invention, the determination means can determine the presence or absence of attachment of a chemical filter capable of removing impurities in air as a specification of the filter, and the impurity concentration is It is also possible to determine that the chemical filter is not attached when the concentration is lower than a predetermined concentration, and determine that the chemical filter is attached when the impurity concentration exceeds the predetermined concentration. In this way, the chemical filter can be attached in a region where the impurity concentration exceeds a predetermined concentration, while the attachment of a chemical filter having a high possibility of excessive removal ability in the region where the impurity concentration is lower than a predetermined concentration can be prevented. . That is, it is possible to select an appropriate filter that prevents excess or deficiency of the removal ability by simple processing.

  In the filter specification determination apparatus of the fuel cell system according to the present invention, the impurity concentration acquiring unit may acquire the concentration of sulfur oxide in air as the impurity concentration. Since the sulfur content in the air has a relatively large influence on the deterioration of the fuel cell, acquiring the concentration information of the sulfur oxide can more appropriately select the filter necessary for removing the impurities.

  In the filter specification determination apparatus of the fuel cell system of the present invention, the fuel cell may be a solid oxide fuel cell. Solid oxide fuel cells react at relatively high temperatures and are prone to deterioration due to impurities such as sulfur in the air. Depending on the concentration of impurities in the area where the fuel cell system is installed, chemical filters may be attached to the air. It is desirable to remove the sulfur content in it. For this reason, the effect by selecting an appropriate filter becomes remarkable.

The storage unit 84 stores impurity concentration information 84 a. The impurity concentration information 84a is information indicating the impurity concentration in the air measured at a plurality of measurement points, and includes impurity concentrations such as sulfur oxide SOx and nitrogen oxide NOx. The control unit 82 acquires the impurity concentration information 84 a via the network 12 and stores the information in the storage unit 84.

Send to 80

  Next, the process of the management system 10 configured as described above, in particular, the process of determining the specifications of the filter 52 attached to the air supply device 50 of the fuel cell system 20 will be described. FIG. 3 is a flowchart showing an example of the filter specification determination processing routine. This routine is executed by the control unit 82 of the management device 80 when the management device 80 receives a request for determination of filter specifications transmitted from the portable terminal 90 of the worker M. When installing (placement) the fuel cell system 20, the worker M prepares a plurality of types (two types in this case) of filters that can be attached as the filter 52, and travels to the site, and the portable terminal 90 at that place. To determine the filter specification.

When this routine is executed, the control unit 82 of the management device 80 first inputs the position information included in the request for determination of the filter specification (S100), and the fuel cell system 10 determines the region corresponding to the position information. An area that has not been installed (hereinafter referred to as the installation area) is acquired (S110). In S100, the control unit 82 inputs the position information of the portable terminal 90 included in the filter specification determination request as the position information at which the fuel cell system 20 is placed. Further, in S110, among the areas corresponding to any of the measurement points in the impurity concentration information 84a, the installation area closest to the position information input in S100 is acquired. Next, the control unit 82 refers to the impurity concentration information 84a stored in the storage unit 84, and acquires the impurity concentration Ic corresponding to the installation area acquired in S110 (S120). In S120, the control unit 82 can obtain the concentration of SO ₂ as the impurity concentration Ic. This is because, as described above, such as degradation of the cathode electrode by a sulfur component contained in the SO ₂ occurs, the influence of deterioration of the fuel cell stack 31 according to SO ₂ is relatively large.

Next, the control unit 82 determines whether the impurity concentration Ic acquired in S120 is less than or equal to a predetermined reference concentration Icref (S130). When the control unit 82 acquires the concentration of SO _{2 in} S120, it may be determined whether or not the predetermined reference concentration Icref is 5 ppb or less in S130. Of course, the reference concentration Icref is not limited to 5 ppb, and may be appropriately determined in consideration of the specifications of each filter that can be attached as the filter 52. As the specification of each filter, for example, the type of filter (removal method), the removal capability (efficiency), the total removal amount of impurities (lifetime), and the like can be considered. The control unit 82 determines that the physical filter is a physical filter (S140) if it is determined in S130 that the impurity concentration Ic is less than or equal to the reference concentration Icref (S140), and determines that the chemical filter is a chemical filter (S150) ). Then, the control unit 82 transmits the type of filter as the determination content to the portable terminal 90 (S160). Further, the control unit 82 associates the installation area, the position information of the fuel cell system 20, and the type of the determined filter with each other and registers them in the storage unit 84 (S170), and ends this routine. When the worker M receives the determination content at the portable terminal 90, the type of filter specified by the determination content can be attached to the fuel cell system 20 as the filter 52.

  Here, the physical filter can be removed by physically collecting and adsorbing impurities such as dust and pollen in the air without performing a chemical reaction, and for example, glass fiber is used as a filter medium So-called HEPA filters can be illustrated. The chemical filter is removable by adsorbing impurities in the air by a chemical reaction (chemical bond), and for example, activated carbon, activated carbon fiber, ion exchange fiber, etc. are used as a filter medium. The chemical filter may be capable of adsorption by physical collection in addition to adsorption by a chemical reaction, for example, by wrapping granular activated carbon in a non-woven fabric. Chemical filters tend to be higher in ability to remove sulfur oxides SOx, nitrogen oxides NOx, etc. than physical filters, and cost is also high. Therefore, by selecting the physical filter when the impurity concentration Ic in the installation area is lower than the predetermined reference concentration Icref, and selecting the chemical filter when the impurity concentration Ic exceeds the predetermined reference concentration Icref, the impurity concentration Ic is Only the filter 52 of the fuel cell system 20 in the high installation area can be a chemical filter. As a result, since the chemical filter is not used in the region where the impurity concentration Ic is low, it is possible to suppress an increase in the cost of the filter 52 more than necessary. Moreover, in the area | region where impurity concentration Ic is high, it becomes possible to remove an impurity appropriately by using a chemical filter.

  The management apparatus 80 described above acquires the impurity concentration Ic in the installation area of the fuel cell system 20 from the impurity concentration information 84a, determines the specification of the filter 52 based on the impurity concentration Ic, and outputs the determined content. Therefore, the operator M can attach an appropriate filter 52 according to the impurity concentration Ic in the installation area of the fuel cell system 20. Therefore, since the deterioration of the fuel cell stack 31 due to the impurities can be appropriately suppressed, the ability of the fuel cell system 20 can be appropriately exhibited, and the life of the filter 52 can be optimized and the cost of the filter 52 can be reduced.

  Further, the management device 80 selects the physical filter when the impurity concentration Ic is lower than or equal to the predetermined reference concentration Icref, and selects the chemical filter when the impurity concentration Ic exceeds the predetermined predetermined concentration Icref. An appropriate filter 52 which prevents the shortage can be selected by a simple process.

Further, since the management device 80 acquires the concentration of SO ₂ as the impurity concentration Ic, the filter 52 suitable for the concentration of SO ₂ having a relatively large influence on the deterioration of the fuel cell stack 31 can be selected.

  In the above-mentioned embodiment, although what is determined as either a physical filter or a chemical filter, that is, the type of filter is determined, the present invention is not limited to this. FIG. 4 is a flowchart showing a filter specification determination processing routine of the modification. Here, this modification is based on the assumption that a physical filter is attached as the filter 52 regardless of the impurity concentration Ic, and furthermore, whether or not the chemical filter is attached as the filter 52 is determined. In the routine of FIG. 4, when it is determined at S130 that the impurity concentration Ic is lower than the reference concentration Icref, the control unit 82 determines that the chemical filter is not attached (S140a) and determines that the impurity concentration Ic exceeds the reference concentration Icref. Then, it is determined that the chemical filter is attached (S150a). Then, the control unit 82 transmits the attachment / non-attachment of the chemical filter as the determination content to the portable terminal 90 (S160), and associates the installation area with the position information of the fuel cell system 20 and the attachment / non-attachment of the determined chemical filter It registers in the memory part 84 (S170a), and ends this routine. Thereby, the physical filter is attached as the filter 52 without attaching the chemical filter in the region where the impurity concentration Ic is lower than the reference concentration Icref, and the physical filter and the chemical filter are attached as the filter 52 in the region where the impurity concentration Ic exceeds the reference concentration Icref be able to. By doing so, in the region where the impurity concentration Ic is high, the physical filter and the chemical filter can be used in combination, so that the impurity can be more appropriately removed. Further, since only the physical filter is used in the area where the impurity concentration Ic is low, it is possible to suppress an increase in the cost of the filter 52. That is, as in the embodiment, it is possible to select an appropriate filter that prevents excess or deficiency of the removal ability by a simple process.

  Further, the type of the filter is not limited to one of the two types, but may be determined as any one of three or more filters having different specifications such as removal capability and life. In such a case, for example, the filter 52 is determined from among three types: a physical filter, a first chemical filter, and a second chemical filter having higher performance such as removal ability and life than the first chemical filter. It is good also as things etc. In addition, in order to extend the life, the type of filter is not limited to the one to be changed, but the life may be extended by increasing the total adsorption amount by increasing the size with the same type of filter.

In the embodiment described above, the specification of the filter 52 is determined using, for example, the concentration of SO ₂ as the impurity concentration Ic. However, the invention is not limited thereto, and the concentration of other impurities such as nitrogen oxide NOx may be used. The specification of the filter 52 may be determined. Further, the specification of the filter 52 is not limited to one type of impurity concentration Ic, and the specification may be determined using a plurality of types of impurity concentrations Ic. In such a case, for example, when the plurality of types of impurity concentrations Ic are all below the reference concentration Icref for each impurity, the first filter is determined, and the number of impurities exceeding the reference concentration Icref is below the predetermined number If the number of impurities exceeding the reference concentration Icref exceeds a predetermined number, the second filter is determined to have a higher performance than the second filter. It may be determined as a filter of

  In the embodiment described above, the specification of the filter 52 is determined when the fuel cell system 20 is installed. However, the present invention is not limited to this. After the filter 52 is once attached to the fuel cell system 20, the specification of the filter 52 is determined. It may be something to be re-determined. Here, the control unit 82 of the management device 80 may update the impurity concentration information 84a every predetermined period such as every several days, every few weeks, every several months, etc., when the impurity concentration information 84a is updated. The specification of the filter 52 may be re-determined or the like. For example, the control unit 82 newly acquires the impurity concentration Ic # from the updated impurity concentration information 84a, and selects an installation area where the impurity concentration Ic # newly exceeds the above-described reference concentration Icref. Next, the type of the filter 52 of each house H in the selected installation area is read, and if there is a house H whose type of the read filter 52 corresponds to the physical filter, the filter in the fuel cell system 20 of the corresponding house H Redetermination is performed by redetermining the chemical filter in 52. Further, the control unit 82 transmits the redetermined content to the remote control panel 25 of the corresponding house H or the portable terminal 90 of the worker M who is in charge of the installation area. This re-determination content includes a message prompting replacement of the filter 52. Therefore, when the redecided content is displayed on the display operation unit 26 of the remote control panel 25 of the house H, the resident of the house H can grasp that the filter 52 needs to be replaced. In addition, when the worker M receives the redecided content by the portable terminal 90, the worker M recognizes that the filter 52 needs to be replaced, and can contact the resident of the house H to perform the replacement work. In this manner, it is possible to promote replacement of the filter 52 appropriately in response to changes in the impurity concentration Ic. Therefore, it is possible to appropriately cope with environmental changes and to appropriately operate the fuel cell system 20 while suppressing deterioration thereof. Alternatively, the control unit 82 may transmit the redecided content to only one of the house H and the worker M.

  In the embodiment, the remote control panel 25 is connected to the network 12 through the communication unit 28. However, the present invention is not limited to this, and the remote control panel 25 may not be connected to the network 12 without the communication unit 28. In such a case, the determination content may be transmitted only to the worker M in S160 of FIG. 3 and FIG.

  In the embodiment, the installation area where the fuel cell system 20 is installed is acquired based on the position information measured by the GPS positioning unit 94 of the mobile terminal 90 of the worker M, but the present invention is not limited thereto. Alternatively, the installation area may be acquired based on area information input by the resident via the remote control panel 25, for example, information such as an address registered by the resident by the user. In such a case, the worker M may work without having the portable terminal 90, or as S160 in FIG. 3 or FIG. Good.

  In the embodiment, the specification of the filter 52 is determined by the management device 80, but the invention is not limited to this. For example, the specification of the filter 52 may be determined by the mobile terminal 90 of the worker M. In order to do so, the control unit 96 of the portable terminal 90 performs the routine of FIG. 3 or FIG. 4, and in S160 of FIG. 3 or FIG. . In addition, the control unit 96 of the portable terminal 90 may obtain impurity concentration information in advance and store it in the storage unit of the portable terminal 90, or obtain impurity concentration information via the network 12 every time the routine is performed. It is also good. When the portable terminal 90 acquires impurity concentration information in advance and stores it in the storage unit, the portable terminal 90 may not have the function of connecting to the network 12 at the installation position (work position) of the fuel cell system 20. Good. When the specification of the filter 52 is determined by the portable terminal 90, the remote control panel 25 may not be connected to the network 12 without the communication unit 28.

  Further, the specification of the filter 52 is not limited to that determined by the management device 80 or the portable terminal 90, and the specification of the filter 52 may be determined by the fuel cell system 200. FIG. 5 is a block diagram schematically showing the configuration of a fuel cell system 200 according to a modification. In FIG. 5, the same components as in FIG. 2 are assigned the same reference numerals and descriptions thereof will be omitted. As illustrated, the fuel cell system 200 includes a control device 170 that controls the entire fuel cell system 200, and a display operation unit 178 provided as a touch panel liquid crystal display. The control device 170 includes a control unit 172, a storage unit 174, and a GPS positioning unit 176. The storage unit 174 stores impurity concentration information 174 a. The impurity concentration information 174 a is information similar to the impurity concentration information 84 a of the embodiment, and is stored, for example, in the storage unit 174 before being shipped from the factory. When a request for determination of filter specifications is received via the display operation unit 178, the control device 170 executes a routine similar to that of FIG. 3 or 4 and displays the determined content on the display operation unit 178. The process of S170 may be omitted. The worker M can attach an appropriate filter 52 in accordance with the display on the display operation unit 178. Therefore, as in the embodiment, it is possible to determine an appropriate filter 52 corresponding to the impurity concentration Ic in the installation area of the fuel cell system 20 and attach it to the worker M. Thus, in this variation, the fuel cell system 200 can independently determine the filter specification. For this reason, without constructing the management system 10 as shown in FIG. 1, each fuel cell system 200 may independently determine the filter specification to be attached to its own device.

  In the embodiment, the filter specification suitable for the installation area of the fuel cell system 20 is determined. However, the present invention is not limited thereto, and the fuel cell system 20 may be placed (installed) before the fuel cell system 20 is placed. For example, a filter specification suitable for a planned planned area may be determined. For example, in a factory where the fuel cell system 20 is manufactured, the manufacturing control apparatus may execute the same routine as that in FIG. 3 or FIG. That is, the manufacturing management apparatus acquires the planned area such as the shipping destination of the fuel cell system 20, acquires the impurity concentration Ic corresponding to the acquired planned area, and determines the filter specification corresponding to the acquired impurity concentration Ic. What is displayed on a work monitor or the like may be used. Thereby, the factory worker can attach the filter 52 of the specification suitable for the planned area according to the display of the work monitor. In the case where the fuel cell system 20 is temporarily stored after being shipped from the factory and then transported to the planned area, it is not limited to the one in which the filter 52 is attached in the factory where the fuel cell system 20 is manufactured. The filter specification may be determined at a place and attached to a storage worker.
