Description
The application is application number is 201410341642.8, and the applying date is on July 17th, 2014, and denomination of invention is the divisional application of the application for a patent for invention of " a kind of bipolar plates for fuel cell and manufacture method thereof "
Technical field
The present invention relates to a kind of bipolar plates for fuel cell and manufacture method thereof.
Background technology
Fuel cell pile bipolar plates (hereinafter referred to as " bipolar plates ") is one of core component of fuel cell shut-down system, its quality accounts for 80% of whole stack system, and its manufacturing cost accounts for 45% of total manufacturing cost of whole fuel cell shut-down system.Fuel cell pile bipolar plates mainly comprises pole plate and flow field two parts; Wherein, the major function of pole plate is conduction, current collection, and the major function in flow field intercepts negative and positive the two poles of the earth gas and guides gas flow in each one pole side.
Based on the needs of fuel cell pile function, when manufacturing bipolar plates, only choose the material simultaneously possessing the character such as conductivity, air-tightness, thermal conductivity, corrosion resistance and certain structural strength, just can produce the bipolar plates meeting the fuel battery double plates basic operating conditions that USDOE specifies.
Main Function due to fuel cell pile is generating, therefore conducts electricity, current collection is the basic function of bipolar plates, so when selecting the material manufacturing bipolar plates, need the functional requirement preferentially meeting conductivity, selects the material of good conductivity.Again because the material thermal conductivity of general good conductivity is also relatively good, and fuel cell pile only reaches certain temperature and could work, and therefore conductive and heat-conductive is the primary condition of stack system work.So when manufacturing fuel cell pile bipolar plates, usual selection possesses the material of conductivity and thermal conductivity, and the conductivity of this material and thermal conductivity all should reach the bipolar plates basic operating conditions that USDOE specifies simultaneously.
The substrate (hereinafter referred to as " substrate ") of bipolar plates is the topmost part of bipolar plates, and can play pole plate and the flow field function of bipolar plates, be the foundation of bipolar plates.Due to the foundation that substrate is bipolar plates, therefore when manufacturing substrate, usually also should select the material simultaneously possessing conductivity and thermal conductivity, and the conductivity of this material and thermal conductivity also all should reach the bipolar plates basic operating conditions that USDOE specifies.
At present, the material that substrate adopts mainly contains two classes: a class is the homogenous material simultaneously possessing thermal conductivity and conductivity, such as metal, pure graphite etc.Another kind of is the composite material simultaneously possessing thermal conductivity and conductivity after being mixed with heat-conductivity conducting material, as composite graphite etc.No matter be homogenous material or composite material, the conductivity that this baseplate material possesses simultaneously and thermal conductivity can reach the fuel battery double plates basic operating conditions that USDOE specifies.But the shortcomings such as although pure graphite has high connductivity, high heat conduction, the advantage such as corrosion-resistant, it is low, frangible that it still exists mechanical strength, and processing cost is high, which limits the extensive use of graphite bi-polar plate.Although metal material possesses high connductivity, high heat conduction, feature that mechanical strength is high, it is not corrosion-resistant, and weight is excessive, and this also makes its popularization face huge obstacle.Although composite graphite material improves mechanical strength compared to graphite material, its difficulty of processing is still very large, and processing cost does not also obviously reduce.Meanwhile, because the resin portion in this composite material does not generally possess conductivity and thermal conductivity, so reduce the performance of bipolar plates.
As can be seen here, due to bipolar plates, mainly the substrate of bipolar plates needs the Performance comparision that possesses many, and the alternate material that comprehensively can meet its various performance requirement is considerably less.Therefore, when selection material, the requirement reduced while preferentially meeting partial properties demand another part performance of having to, this reduces the efficiency of fuel cell, creates certain impact simultaneously on the performance of fuel cell.Meanwhile, the limitation of this selection material, also add the volume of fuel cell, weight, increases the difficulty of manufacture, improves manufacturing cost, becomes a huge technical bottleneck, seriously hinders fuel cell development in many-side.The manufacturing technology of fuel cell pile bipolar plates is one of fuel cell power generation part two large core technologies of dividing.At present, huge strength has all been dropped into for the research of bipolar plate material in countries in the world, to seek a kind ofly to widen selection range while lifting bipolar plates performance, reduce bipolar plates and the manufacture method thereof of the fuel cell of manufacturing cost and difficulty of processing to greatest extent.Bipolar plates provided by the invention and manufacture method thereof solve this problem, and considerably reduce the manufacturing cost of bipolar plates, as large-scale promotion, and will in the huge competitive advantage of the fuel cell Establishing Market in future.
