Each battery 19 produces heat from its power generation part, and is only influenced by ambient temperature via outside parts 24 but first wall 43 does not produce heat.Therefore, between battery 19 and first wall 43 thermal dilation difference appears.Relax this thermal dilation difference by between battery 19 and first wall 43, being provided with at interval or deformable bond being set in this interval.Should point out, adjacent many battery modules 40 have the midfeather of extending along the battery stack direction between the first wall 43 and between the bond 45, thereby bond 45 can be along thermal expansion freely of battery stack direction or distortion, and can be along the direction distortion perpendicular to the battery stack direction.
Be provided with outside limits parts 46 between the outer surface of the first wall 43 of the inner surface of side component 24 and many battery modules 40 outside.Wish that outside limits parts 46 are formed by deformable material, so that absorb between the inner surface of the outer surface of each first wall 43 and outside parts 24 along difference perpendicular to the thermal expansion of the direction of battery stack direction.The example of this deformable material comprises resin, is mixed with the epoxy material of glass etc.The material of outside limits parts 46 is not limited to resin or is mixed with the epoxy parts of glass.
Owing between the inner surface of the outer surface of each first wall 43 and outside parts 24, be provided with outside limits parts 46, so can receive the inertia force that acts under the situation such as vehicle collisions on many battery modules 40 by outside parts 24.Outside limits parts 46 are formed by deformable material, thereby can absorb between the inner surface of the outer surface of each first wall 43 and outside parts 24 along the difference perpendicular to the thermal expansion of the direction of battery stack direction.
On the battery stack direction, spring box 47 is set with respect to a plurality of many battery modules 40 series connection that are provided with along the series connection of battery stack direction.The spring force of spring box 47 (permanent load) is applied on each many battery module 40 along the battery stack direction.Spring box 47 has a plurality of screws 48 that are arranged in parallel.Spring box 47 is arranged in the end of duplexer 23, and this end is relative with supply pipe is connected duplexer 23 thereon with delivery pipe end.Spring box 47 is arranged between insulator 21 and the end plate 22.The spring force of spring box 47 can be regulated by the adjustment screw 49 that is arranged between spring box 47 and the end plate 22.Spring box 47 can omit.
Except the first wall 43 that extends along the battery stack direction, each frame module 42 also can have second wall 44, and this second wall 44 extends along the direction perpendicular to the battery stack direction, and has rigidity on the direction perpendicular to the battery stack direction.Second wall 44 can omit.
If the module frame 42 of many battery modules 40 has second wall 44, then many battery modules 40 can have structure as shown in Figure 2, wherein battery component 41 more than two is arranged on the opposite side of second wall 44 along the battery stack direction, perhaps can have structure as shown in Figure 3, one of them many battery component 41 is arranged on the side of second wall 44 along the battery stack direction.
If module frame 42 has second wall 44, then second wall 44 need have conductivity.As for first wall 43, conductivity is optional fully.
Next, will the operation and the advantage of part identical in all embodiments of the invention disclosed herein be described.
In the fuel cell module of the prior art shown in Figure 30, the cross force that acts on the stacked battery only is supported in two opposite end.When bump takes place, if being the stacked battery of M, total weight is subjected to transverse acceleration α, then cross force M α acts on the entire cell duplexer, so shearing force M α/2 act on the module of two opposite ends of stacked battery.
On the contrary, under the situation of fuel cell module 10 of the present invention, duplexer 23 is divided into a plurality of many battery modules 40, and provides a kind of setting so that receive the cross force that acts on many battery modules 40 by outside parts 24 along the direction perpendicular to the battery stack direction.Therefore, many battery modules 40 are subjected to the cross force of M α/n, and wherein M is the total weight of stacked battery, the transverse acceleration that produces when α is bump, and n is the quantity of many battery modules in the duplexer 23.If this cross force is supported in two opposite ends of many battery modules, then shearing force becomes M α/(2n).Therefore, fuel cell module 10 of the present invention can bear very big gravity impact transversely.
Unlike the prior art, being applied to spring force on many battery modules 40 along the battery stack direction does not need the same greatly with the power that produces the frictional force that overcomes shearing force M α/2, reduces to electrically contact the required power of resistance but can be as small as.Therefore, the spring force that applies along the battery stack direction can reduce from the level of prior art.As a result, the creep compliance of MEA and diffusion layer reduces.
In addition, because duplexer 23 is divided into a plurality of many battery modules 40, so unlike the prior art, MEA that is caused by creep etc. is not concentrated on the battery of two opposite ends that are arranged at this duplexer along the displacement of battery stack direction, but is dispersed in many battery modules 40.Therefore, compared with prior art, the battery 19 of many battery modules 40 reduces greatly along the displacement of battery stack direction.In addition, owing to reduce by the creep compliance of the spring force generation that reduces, so the displacement of the battery 19 of many battery modules 40 also reduces.Therefore, all have under the situation of first wall 43 at each module frame 42, many battery modules 40 reduce with respect to the displacement of outside limits parts 46 along the battery stack direction.Therefore, even creep takes place in MEA etc., very big displacement can not take place with respect to outside limits parts 46 in the battery 19 of many battery modules 40 yet, thereby therefore will can not take place because this displacement causes battery 19 to stick to the situation that causes damaging battery 19 on the outside limits parts 16.
Because many battery components 41 of many battery modules 40 are not limited by module frame 42 on the battery stack direction, so the difference along the thermal expansion of battery stack direction can not cause damaging battery 19 between many battery components 41 and the module frame 42.
If two opposite ends of the first wall 43 of module frame 42 are towards many battery component 41 1 lateral bending songs, thereby the sweep of first wall 43 has limited the opposite end along the battery stack direction of many battery components 41 and has moved on the battery stack direction, then the thermal dilation difference along the battery stack direction will cause the sweep of first wall to push the carbon dividing plate of battery 19 consumingly between first wall 43 and the many battery components 41, and this can cause damaging the carbon dividing plate.But in the present invention, owing to many battery modules 40 are not limited by module frame 42 on the battery stack direction, so will can not damage the carbon dividing plate.
If the battery 19 in many battery modules 40 is bonding mutually at its battery surface place, the also bonded intensity of at least a portion of shearing force is born between the battery that the cross force of then impacting for example vehicle collision etc. produces when acting on many battery modules 40.In addition in the present invention, this shearing force is less as mentioned above, therefore the side knock of very big gravity more easy to deal with.In addition, battery is in the absence of its outer surface alignment (protuberance or depressed part) in the bonding mutually structure therein, if because the creep of MEA etc. makes the battery outer surface along the battery stack direction with respect to bond 45 (promptly, be arranged on the bond 45 between the first wall 43 of battery outer surface and module frame 42) relative displacement takes place, battery 19 can not bond on the bond 45 yet and battery 19 can not damage.
Between the inner surface of the first wall 43 of the module frame 42 of the outer surface of many battery components 41 of many battery modules 40 and many battery modules 40, form at interval or be provided with under the situation of deformability bond 45 therein, can discharge battery 19 creeping displacement and thermal expansion with respect to module frame 42 and bond 45 on perpendicular to the direction of battery stack direction, and can not cause battery 19 and module frame 42 or bond 45 bond together mutually (if when perhaps battery 19 is bonded on module frame 42 or the bond 45, the distortion by bond 45 discharges (this creeping displacement and thermal expansion)).
Owing between the outer surface of the first wall 43 of the module frame 42 of the inner surface of parts 24 and many battery modules 40, can bear reliably by outside parts 24 outside outside limits parts 46 are arranged on so act on the cross force of the impact on many battery modules 40.The temperature of outside parts 24 is influenced by ambient temperature, and the temperature of many battery modules 40 is subjected to the heat effects that produces during battery 19 generating.Therefore, between them, have the temperature difference, thereby the thermal expansion between them there are differences.But, the difference of the thermal expansion outside can relaxing by the distortion of outside limits parts 46 between parts 24 and the many battery modules 40.
Under many therein battery modules 40 are connected situation about being provided with along many battery modules 40 that the series connection of battery stack direction is provided with and spring box 47 is provided with respect to series connection along the battery stack direction, if duplexer 23 is divided into a plurality of many battery modules 40, the permanent load of the spring force of spring box 47 is acted on all many battery modules 40 of duplexer 23.In addition, owing to spring 48 is used to apply permanent load along the battery stack direction on many battery modules 40, so if the thermal expansion of many battery modules 40 or the deformation of creep-generation-can be absorbed by spring 48, and permanent load does not change basically.
Next the peculiar part of each embodiment of the present invention will be described.
In embodiments of the invention 1, shown in Fig. 1 to 4, each module frame 42 has the first wall 43 that extends along the battery stack direction, and along second wall 44 that extends perpendicular to the direction of battery stack direction.Second wall 44 is by the material with conductivity, for example formation such as metal material such as SUS.First wall 43 can be formed by electric conducting material or non-conducting material.For example, first wall 43 can be formed by resin or metal material such as SUS etc.The inner peripheral surface of the outer peripheral face of second wall 44 and first wall 43 is connected together, or forms.
The dividing plate adjacent with second wall 44 of many battery components 41 can be bonded on the second adjacent wall 44 by the sealing bonding agent, perhaps can seal and not bond on second wall 44 via O type ring 50 usefulness second wall 44.
The operation and the advantage of embodiments of the invention 1 will be described below.At least a portion of the cross force of the impact that takes place on many battery components 41 is delivered to first wall 43 via second wall 44, and is received from first wall 43 by outside parts 24 via outside limits parts 46.Be present at bond 45 under the situation between the inner surface of the outer surface of many battery components 41 and first wall 43, the part of the cross force of the impact that takes place on many battery components 41 is delivered to first wall 43 via bond 45.
If cross force is from the outside, then the cross force from outside parts 24 enters first wall 43 via outside limits parts 46.Because this load is born by second wall 44, so there is not external load to enter many battery components 41 basically.In addition, because therefore first wall 43 disperses the load from the outside, and reduce the surface pressing on the battery 19, so even can prevent still under the situation that is provided with bond 45 that battery 19 from bonding on the bond 45 along the battery stack direction.
