Description
Technical field
The present invention relates to field of fuel cell technology more particularly to a kind of clamp devices of easy fuel cell pack.
Background technology
Fuel cell is a kind of device that chemical energy is directly translated into electric energy, since its is efficient, zero-emission, starts temperature
It spends low, is highly suitable in communications and transportation, stationary power generation and portable domain.In recent years, countries in the world are all actively being ground
Study carefully and is applied to automotive field using fuel cell as power source.Since the voltage of monolithic battery is small, automobile power cannot be satisfied
Demand, it is therefore desirable to several pieces of cells in series be fitted together into composition pile, and fastened by mechanical pressure, if fastening
Pressure is excessive, easy tos produce rupture or deformation that stress concentration causes the key components and parts such as membrane electrode or pole plate, or even pierce through and tear
A series of problems, such as splitting, while can also reduce the porosity of gas diffusion layers, gas leakage, reduced performance, service life is caused to reduce,
If fastening pressure is too small, contact resistance easy to increase causes Performance data to decline, so, fastening pressure appropriate is for electricity
The performance of heap, safety method and durability are most important.In general, complicated fastening method is easy to bring more stress concentration
Problem and cumbersome assembly program, reliability is not high, and efficiency is low, therefore, finds a kind of simple, compact, light-weight fastening side
Method is of great significance.
Currently, most of pile fastenings are by the way of screw rod fastening.Wherein, there are many intrinsic for screw rod fastening means
Disadvantage.First, the sectional area of pile is increased, and then increases pile volume, is unfavorable for improving the volumetric power density of pile.
Secondly, screw rod and the position stress that nut fastens are big, usually require that tailgate carrys out uniform conducting pressure with certain thickness, are
This must increase the thickness of tailgate, can thus increase volume and weight, this is unfavorable for the power density for improving pile.
Finally, due to which multigroup screw rod needs to fasten, assembly and disassembly process is cumbersome, and efficiency is low, and it is difficult to ensure that power between every group of screw rod
Consistency, cause pile discontinuity.
Include sequentially gas port application No. is a kind of fastening structure is disclosed in 201710138182.2 application for a patent for invention
End plate, gas port end collector plate, flow-field plate and membrane electrode assembly, cecum collector plate and pile elastic compensating structure, above structure is successively
It is fastened with multigroup pulling belt structure, pulling belt structure includes U-shaped metal drawstring, and the ends bent of metal drawstring is at the circle with T-bolt
It is welded at the drawstring end lap of metal drawstring after the matched annulus of bar, the T-bolt on metal drawstring passes through gas port end plate
On mounting hole, pass through nut and gas port end plate connection and fasten.The fastening structure is limited in that：1. using spring and pressing plate
Mode realizes pile elastic compensating structure, increases fuel cell volume and weight；2. being fastened using pulling belt structure, carrying out
It when assembling, the matching of metal drawstring and T-bolt and is fastened by nut and gas port end plate connection, the structure practical operation is multiple
It is miscellaneous and very high to the consistency of fastening force and dress heap technological requirement.
