Description

Fuel cell is device fixedly

Technical field

The utility model is about a kind of fixture, especially in regard to a kind of fixture of fuel cell.

Background technology

In recent years because the lasting consumption of traditional energy such as coal, petroleum and natural gas, cause the severe contamination of earth environment and the greenhouse effect in the whole world, therefore scientist desires most ardently the scheme that solves of seeking, reducing using and relying on of traditional energy, and fuel cell (fuel cell) is wherein a kind of selection of important and tool development potentiality and practical value.Compare with traditional internal combustion engine, fuel cell has energy conversion efficiency height, running peace and quiet, reacts advantages such as fast and low-down exhaust emission, therefore, become the power resources of motor vehicles for example or mobile generator or portable electric equipment apace.

Fig. 1 is the schematic perspective view of known a kind of fuel battery 1 assembling.Fuel battery 1 comprises two end plates (endplates) 111 and 112, a plurality of fuel cell 12 and a plurality of screw rod 13, the sheathed respectively spring 14 of each screw rod 13, two packing rings 151 and 152, and two nuts 161 and 162.Be clear expression, present embodiment is that two offsides that are separately positioned on fuel cell 12 with two screw rods 13 are example, as shown in Figure 1.

During fuel battery 1 assembling, be together with a plurality of fuel cell 12 storehouses, again the battery pack behind the storehouse is put between end plate 111 and 112, and then many screw rods 13 are passed end plate 111 and 112 respectively, make and insert and put a plurality of fuel cells 12 between end plate 111 and 112, then, end (for example left end of Fig. 1 screw rod 13) at each screw rod 13, distinguish a sheathed spring 14, a packing ring 151 and a nut 161 in regular turn, make the left end of screw rod 13 pass spring 14, packing ring 151 and nut 161 in regular turn respectively.In addition, after the other end of screw rod 13 wears another packing ring 152 and another nut 162 in regular turn respectively, distinguish lock nut 161 and 162 again, so that being imposed one, two end plates 111 and 112 insert and put strength, by the locking of nut 161 and 162 and the elastic force of spring 14, make two end plates 111 and 112 fuel cell 12 can be compressed and fit together.

Yet above-mentioned number of assembling steps possibly can't be finished so smoothly, and following 2 problems might take place:

First: because the fuel cell behind the storehouse is quite heavy, so must select for use and have enough rigidity and flexible spring, therefore, the spring body must reach slightly, relative will having under the enough flexible situation also must have bigger internal diameter, and the diameter of the general screw rod of using always is compared relative little a lot (as shown in Figure 1) with the internal diameter of spring.At the screw rod of minor diameter and the spring of large diameter, the packing ring and the nut that do not have general common-use size are applicable, and therefore, the present practice is to open new die in addition with tailor-made suitable nut.Yet it is many that tailor-made expense will make that the cost of fuel cell increases again, moreover even if the tailor-made not good problem in spring location that also can't solve.

Second: if the packing ring that finds common-use size reluctantly is to be suitable for this spring, then the hole in the middle of the described packing ring of possibility is quite big.But less relatively because of the diameter of screw rod, so that it is also less relatively to mate the diameter of nut of described screw rod, might cause nut pass in the middle of the described packing ring hole and can't fixing spring.

Therefore, how to provide fixedly device of a kind of fuel cell, make it be useful in the fixing of fuel cell, and do not need the required great number cost expenditure of additionally tailor-made parts, real is one of current important problem.
