Description
[technical field]
The utility model relates to the fuel cell pile technical field, specifically a kind of fixture of fuel cell pile.
[background technology]
Got into since 21st century, fuel cell is with its environmental protection and efficiently become one of the most very powerful and exceedingly arrogant energy.The core of fuel cell is a pile, and two bipolar plates and MEA form battery unit, becomes a battery pack after several battery units stacks, and the pressure between each battery pack between the contacted bipolar plates is influential to the pile power output.
In fixing this technical field of fuel cell pile, comparatively traditional fixed structure connects fixing by a plurality of fixed levers for outside battery pack, to add two end plates between two end plates.The defective of this fixed structure is troublesome poeration, is unfavorable for increasing the volumetric specific power of pile; When the compression adjustment, because pile pressure uneven (pressure is at an end of plate) can make bipolar plates (carbon plate) or MEA damage because of adjustment amount is excessive.
CN1614797 discloses a kind of fixed mechanism of fuel battery, and the fixed band that adopts fiber reinforcement polymeric material or stainless steel to process carries out sealing and fixing to whole battery group.Its shortcoming is that fixed band is once production; Its general frame shape all can't change, and if a little difference in height is arranged between the battery pack, promptly use nut, rivet or scolder to connect; Still can be because of existing difference in height to cause system pressure not adjust; Can influence system's power output, also might cause poorly sealedly because of the scale error reason, or compress excessive and bipolar plates or MEA are damaged.
[summary of the invention]
For addressing the above problem, the utility model provides a kind of pile fixture that can adjust according to actual conditions.
A kind of fixture of fuel cell pile; Comprise fixed band (1) and top board (4), it is characterized in that said fixed band (1) constitutes frame structure, but the frame downwarping of fixed band top; Said top board (4) surface is fluted, and said fixed band is fixed in said top board.
Be provided with or be not provided with locking hole (2) in the middle of the frame of said fixed band (1) top, have screwed hole or be fixed with double-screw bolt on said top board (4) surface groove.
The locking hole of said fixed band (1) is corresponding with the screwed hole position of top board (4) surface groove, and said fixed band and said top board are by screw.
The locking hole of said fixed band (1) passes the double-screw bolt of top board (4) surface groove, and said fixed band and said top board are fixed by nut.
Said fixed band (1) and top board (4) are fixing through briquetting (7), and briquetting (7) is provided with through hole (8), and said through hole is corresponding with the screwed hole or the double-screw bolt position of top board (4) surface groove, and said fixed band and said top board are fixed by screw or nut.
Said briquetting (7) embeds said top board (4) surface groove.
All inside bending 90 degree of said fixed band (1) left and right sides constitute the bottom frames, and said bottom frame fore-end bends 90 degree downwards and constitutes the vertical fixing plates, and said left and right sides vertical fixing plate is provided with fixing hole (3).
All inside bending 90 degree in described fixed band (1) left and right sides constitute the bottom frames, and said left and right sides frame and bottom frame are provided with fixing hole (3).
Described fixed band (1) two ends are adopted one-shot forming or are welded to connect, and constitute closed frame.
Described fixed band (1) adopts metal material or fiber to strengthen polymeric material.
The flexibility of described fixed band (1) top frame can free adjustment.
The fixed band of the said fixture of the utility model adopts metal material or fiber to strengthen polymeric material; Like stainless steel or plastic-steel band etc.; The top board surface has groove; Have screwed hole in the groove or be fixed with double-screw bolt, press down through screw, nut or briquetting to be fixed band downwards, pile is reached be fastenedly connected freely regulated purpose.Because MEA can cause the pile size different with the bipolar plates thickness error, but adopt the fixture of free adjustment pile height, to reach the needed actual size of pile.Advantage is:
Convenient when 1, installing and freely adjusting, reliable, freely adjusting does not need to carry out on the press.
2, can effectively improve the volumetric specific power of pile.
3, gas that causes or fluid leakage problems have been solved because pile is poorly sealed.
4, because the top board surface groove screwed hole or the position of double-screw bolt or the pressing position that utilizes briquetting to press down fixed band are the centres at the pile top board; Therefore when freely adjusting the pile size; The pressing plate of pile is to receive downward pressure, can not damaged by pressure because of unbalance stress causes bipolar plates or MEA.
5, can be according to needed pressure of system and the next size of freely adjusting pile of sealing.
