Technical field:
The utility model belongs to the manufacture method of fuel cell key components and parts servicing unit in the fuel cell manufacturing field, particularly a kind of vacuum impregnation plant that is used for fuel cell core component carbon plate.
Background technology:
Proton Exchange Membrane Fuel Cells is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) that directly chemical energy in fuel and the oxidant is converted into continuously electric energy.In each assembly of battery, bipolar plates plays an important role, and difform water conservancy diversion groove is carved with on its surface, in order to transmit fuel and oxidant, discharges water and the remaining waste gas of reaction that reaction generates simultaneously; The rib of water conservancy diversion groove then closely contacts with the diffusion layer of electrode, has formed the passage of electron transport, and therefore, the distribution of water conservancy diversion groove and form have determined the distribution of reacting gas and operating current on the bipolar plates, thereby affects the performance of battery.Bipolar plates must be airtight, can not use porous air pervious material; Has very strong resistance to corrosion, anti-strong acidity or alkaline; Must be the good conductor of heat, guarantee that the even distribution of temperature and the heat radiation of battery pack is good.
Various countries are very extensive for the development of bipolar plates in recent years, comprise graphite cake, compound bipolar plates, metallic plate etc.Because metallic plate uses under sour environment for a long time and is easy to corrosion, the metal ion that dissolves can produce polymer dielectric and pollute, and also causes the contact resistance of metal and electrode diffusion layer excessive, and the ohm voltage drop of discharge generation is too high under big current condition.So most at present employing graphite cake machinings or compound graphite material are pressed into the monolithic carbon plate, reprocessing is integrated and is formed bipolar plates.
But graphite cake produces the small open pore of structure in plate owing to coal tar, pitch generation thermal decomposition, coking and the volatilization used as bonding agent in roasting process.Also to have new hole residual because the evaporation of ash impurity is overflowed after the graphitization that is higher than under 2000 ℃ in addition, causes the graphite cake surface to produce 20～30% pore.The oxidation rate of graphite electrode has been accelerated in the existence of pore, makes rupture strength, compression strength, modulus of elasticity and the conductivity of electrode that in various degree decline all be arranged.Fuel cell carbon plate particularly, the increase of the carbon plate electrode porosity makes fuel gas mixing to a certain degree occur before electrochemical reaction takes place, reduced the valid density of fuel gas, thereby influence fuel cell performance, therefore be necessary the carbon plate of afflux is handled to reduce the porosity, improve the carbon plate quality.
Summary of the invention:
The purpose of this utility model provides a kind of vacuum impregnation plant that is used for fuel cell core component carbon plate.This apparatus structure is novel in design unique, manipulates simple and conveniently, and the operation scheme of high efficiency, low cost can be provided.
Carbon plate vacuum impregnation plant described in the utility model is by switching valve, the mobile vacuum sealing drum, upright to support column, fixing vacuum seal tube, air inlet pipeline, the motion cylinder, the vacuum attraction interface, sealing and fixing frame, chassis and the carbon plate composition that needs the dipping leak stopping, fill maceration extract in the mobile vacuum sealing drum, need the carbon plate of dipping leak stopping to be installed in fixedly and be connected with the motion cylinder in the vacuum seal tube, the hasp on the sealing and fixing frame about two sealing drums couple together, the centre has seal washer, form an airtight system, airtight system is vacuumized processing by the vacuum attraction interface.
Described carbon plate vacuum impregnation plant, its chassis and upright to support column employing fine aluminium, aluminium alloy or stainless steel.The mobile vacuum sealing drum and fixedly the vacuum seal tube adopt toughened glass, polymethyl methacrylate or stainless steel, external diameter 50～300mm, height 200～450mm.The motion cylinder adopts pneumatic control, and the source of the gas of air pump or air compressor machine supply inserts the air inlet pipeline of motion cylinder, comes moving up and down of controlled motion cylinder by switching valve.Switching valve is positioned at the bottom of this device, between motion cylinder and the gas source inlet.Maceration extract adopts coal tar, pitch or various types of resins.The carbon plate that needs the dipping leak stopping is to fire the leachy carbon plate that graphite cake engraving moulding or compound material compression molding are made.
Described carbon plate vacuum impregnation plant, the carbon plate installation that in use will need earlier to flood leak stopping is suspended on the fixedly interior fixed position that is connected with the motion cylinder of vacuum seal tube, to fill maceration extract in the mobile vacuum sealing drum simultaneously, couple together by two sealing drums about the handle of the hasp on the sealing and fixing frame then, the centre has seal washer, forms an airtight system.Vacuum pump is inserted the vacuum attraction interface, airtight system is vacuumized processing, the control pressure range is 400～700mmHg.
The motion cylinder of this carbon plate vacuum impregnation plant is to adopt pneumatic control, be used for moving up and down the good carbon plate of suspension, the source of the gas of air pump or air compressor machine supply inserts the air inlet pipeline of motion cylinder, just can come the flow direction of control gaseous by switching valve, and then the control carbon plate moves down and is immersed in 1～30min in the maceration extract, to be impregnatedly carbon plate upwards retracted after fully, after liquid to be impregnated dries fully, close vacuum pump, the carbon plate that dipping is good takes out.
