Description
Technical field
The present invention relates to proton exchange fuel cell fields, and in particular to a kind of pem fuel cell stack steel band is tight
It is fixedly mounted with and sets.
Background technique
Fuel cell is the device that the chemical energy of Oxidizing and Reducing Agents is directly changed into electric energy by electrocatalytic reaction,
It is a kind of efficient, safe and clean, flexible novel power generation device.Proton Exchange Membrane Fuel Cells therein is because it is with efficiency
It is high, energy density is big, reaction temperature is low, the remarkable advantages such as noiseless, pollution-free, and at terrestrial power generation station, electric vehicle and portable
Formula power supply etc. is with a wide range of applications.Fuel battery inside mainly by proton exchange membrane, electro chemical catalyst,
Diffusion layer and bipolar plates composition.When the fuel cell is operating, internal that following reaction process occur: reaction gas is in diffusion layer
By Catalyst Adsorption and electrocatalytic reaction occurs for diffusion in Catalytic Layer when reaction gas reaches Catalytic Layer；Anode reaction is raw
At proton by being transmitted to cathode side in proton exchange membrane, electronics reaches cathode through external circuit, with oxygen molecule reaction bonded at
Water, while releasing heat.Electrode reaction are as follows:
Anode (cathode): H2→2H++2e
Cathode (anode): 1/2O2+2H++2e→H2O
Cell reaction: H2+1/2O2→H2O
In one typical Proton Exchange Membrane Fuel Cells, membrane electrode is placed among two pieces of conductive guide plates, and two pieces
Deflector is the deflector of anode fuel and the deflector of cathode oxidant respectively.The fuel cell formed in this way is known as single
Battery, in order to increase the general power of entire Proton Exchange Membrane Fuel Cells, need by multiple monocells directly fold by way of string
It is unified into battery pack, is called fuel cell pack.In a fuel cell stack, the two sides of one piece of pole plate can have diversion trench, wherein one
Face can be used as the anode guide face an of membrane electrode, another side but also as another adjacent membrane electrode cathode diversion face,
This pole plate is called bipolar plates.Pile is tightened together by front end-plate, end plate and screw rod.
Traditional pile fastens pile using screw rod, and end plate has a small amount of buckling phenomenon before and after this mode will cause pile,
Uneven to membrane electrode and graphite plate pressure, dismounting pile is cumbersome.
It compares patent " a kind of 200720199028.8 encapsulation apparatus for fastening belt ", its deficiency is:
1. using the stainless steel band of thickness 0.1-0.5cm, steel band is before use, that shape must be first bent into, once it rolls over
Curved good, the length of steel band intermediate straight portion also just secures, but the reason of " graphite plate and membrane electrode " among fuel cell
Want that compressing length can not accurately know in advance, need to adjust during activation test, so steel band in that patent is once
It can not be just finely adjusted after installation, it can not fine control to Performance data.
2. expanding with heat and contract with cold as temperature change generates, elasticity reduction, the deformation of graphite plate face seal glue of membrane electrode, make
Change at the length of " graphite plate and membrane electrode " among fuel cell, and such steel band structure, this length can not be adapted to and become
Change, certain performance can be caused to influence on fuel cell.
It compares patent " a kind of 201420347326.7 fuel cell pack steel band cluster locking mechanism ", its deficiency has:
1. battery is finished in assembly equipment assembly, after battery is removed from assembly equipment, further to fasten, it is necessary to
With very big rotary force, spanner is limited by battery side, rotation can only within a certain angle,
2. during the fastening process, steel band, which can be twisted, encounters graphite plate.
