Embodiment five
Below with reference to Fig. 1, Fig. 3, Figure 21, Figure 22 description according to the fuel cell separator part of the utility model embodiment.
As shown in Fig. 1, Fig. 3, Figure 21, Figure 22, fuel cell separator part includes: reaction zone and marginal zone, and marginal zone is surround
Reaction zone, such as reaction zone can be rectangle, and marginal zone can be rectangle frame, it should be noted that above-mentioned rectangle and rectangle frame
It is not limited in standard rectangular and standard rectangular frame, such as fuel cell separator part shown in Fig. 3, four exterior angles of marginal zone
Place can be equipped with notch.
Marginal zone is equipped with escape groove 77, and escape groove 77 is for being pressed fuel cell separator part, and escape groove 77 is along fuel cell
The thickness direction of separator runs through marginal zone, and distance of the escape groove 77 close to the edge of reaction zone to reaction zone is c, meets: c >=
20mm。
It is understood that fuel cell pile is stacked structure, fuel cell separator part is also stacked structure, will fired
When material battery separators are stacked as fuel cell pile, need to compress fuel cell separator part using fastener, so that each
Fuel cell separator part can fit closely, and fastener is through escape groove 77 to run through combustion on the stacking direction of fuel cell pile
Expect battery stack.
By the way that escape groove 77 is directly arranged in marginal zone, thus it is pressed frame without in addition setting, can greatly simplifies
Press mounting structure, and since fastening force can directly act on fuel cell separator part, apply relatively smaller fastening force so i.e.
The press fitting for meeting sealing can be achieved, and the pressure for being pressed each region of post fuel battery stack is more balanced, fuel cell electricity
The performance of heap is more preferable.
Distance c of the escape groove 77 close to the edge of reaction zone to reaction zone is the edge to the edge of reaction zone of escape groove 77
The shortest distance, which influences the sealing effect of reaction zone.Inventor is had found by many experiments, limits escape groove 77
After above range, the marginal zone as caused by setting escape groove 77 subtracts distance c close to the edge of reaction zone to reaction zone
Thin effect does not interfere with the sealing to reaction zone.Such as c=25mm perhaps c=30mm or c=40mm.
According to the fuel cell separator part of the utility model embodiment, by the way that above structure form is directly arranged in reaction zone
Escape groove 77, facilitate simplify fuel cell pile press-loading process, do not influence the sealing effect of reaction zone, and make fuel
