Description
The present invention relates to fuel cell technology, the bipolar plate structure of a proton exchanging film fuel battery is provided especially.
Fuel cell is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that a kind of chemical energy that will be stored in fuel and the oxidant is converted into electric energy.Its generation mode is the same with the conventional chemical power supply, electrode provides the place of electron transfer, the oxidizing process of anode-catalyzed fuel (as hydrogen etc.), the reduction process of cathode catalysis oxidant (as oxygen etc.), move in the electrolyte of conductive ion between cathode and anode, electronics is by the external circuit work done and constitute the loop of total electricity.In battery, chemical energy carries out to the conversion process isothermal ground of electric energy, promptly in fuel cell, can utilize the free energy of reaction under its operating temperature.But the working method of fuel cell is different with the chemical power source of routine again, and its fuel and oxidant are not to be stored in the battery, but are stored in the basin of outside batteries.When battery operated, continuously in battery, send into fuel and oxidant, discharge product simultaneously; And to discharge used heat, to keep the constant of battery operated temperature.Fuel cell itself only determines the size of power output, and the energy of storing is then determined by the reservoir capacity of fuel and oxidant.Naturally since the invention of material battery, people have developed pluralities of fuel batteries such as alkalescence, phosphatic type, proton exchange model, fused carbonate type and high-temperature solid oxide type.But the energy conversion efficiency of wherein high-specific-power room temperature starting, the quick proton exchange model fuel cell that starts has reached 50%, and it is many-sided preferred removable power supplys such as electric motor car, submarine, open-air battlefield.The external Comprehensive Assessment that various electrokinetic cells are carried out shows, can reach the Proton Exchange Membrane Fuel Cells that has only of present internal-combustion engines vehicle level.The good just application prospect and the progress of dielectric film have promoted the development of Proton Exchange Membrane Fuel Cells.Since this century the eighties, comprised that many developed countries such as the U.S., Canada, Japan all throw huge fund and develop this technology.At present, except that this technology is further developed, striven putting on market, still there are many technological difficulties to still need and further investigate, comprising the flow field structure of battery component bipolar plates, material, processing cost etc.This patent is head it off and an invention making.Many work this had been done abroad.Document [1] USP 5,300,370 Apr.5, the smooth plate that 1994 adopt thin slice to coincide forms is made bipolar plates and is constituted Proton Exchange Membrane Fuel Cells.This flow-field plate is divided into three layers, and the centre is the electrical conduction current demarcation strip, and both sides are equipped with the baffler of 2 tracts of decorative pattern shape grooves respectively.These two kinds of plates are all made with graphite or graphite foil, and also available metal niobium, magnesium, copper and gold and platinum are made, and get its conductive characteristic.The electrical conduction current demarcation strip is the sheet plate of airtight liquid.The baffler of decorative pattern shape groove is to have the sheet plate that strip shape gob is made passage, has a passage between the import and export at least, and its passage can be communicated with, and is also disconnected.When not being communicated with, pass through between platen surface that reaction gas is separated by by passage and the slit between the electrocatalyst layers.The baffler of decorative pattern shape groove can be by punching press, mill or mold pressing is processed.Document [2] USP 4,826,741 May.2,1989 bipolar plate structure are complicated, and the thin plate of airtight with a slice earlier and conduction and hydrophilic and element saturating liquid compresses cooperates with gas distribution plate again.Insert three-in-one (EMA) electrode assemblie between two gas distribution plates.Gas distribution plate simultaneously is processed with groove towards electrode.These distribution plates are all made so that porous stone is black.Document [3] USP 5,382,478 Jan.17,1995 figures that provided show that this battery adopts the gas stream field plate that is similar to document [1], but its groove is continuous, and are the multichannel parallel connection.Above-mentioned document all exists a common problem still unresolved: i.e. gas passage air inlet place is the same with the place of giving vent to anger, make reaction gas in the electrode surface maldistribution, can't obtain making full use of of Catalytic Layer, and air inflow consumption gradually according to its length when electrode is worked, air velocity is different everywhere, especially tail gas place, gas obviously consumes, and passage still, makes gas transfer be in unfavoured state, and the processing charges height causes the battery cost to increase.
The object of the present invention is to provide the bipolar plate structure of a proton exchanging film fuel battery, it can improve the utilance of reaction gas, promotes the mass transfer of electrode surface, thereby improves battery performance, and handling ease, manufacturing expense are lower.
The invention provides the bipolar plates of a proton exchanging film fuel battery, constitute by three layers of metal sheet, the centre is the demarcation strip of the airtight liquid of electrical conduction current, both sides are equipped with the baffler of tape shape groove respectively, it is characterized in that: the strip-shaped grooves on the baffler is continuous by the gas access to gas vent; And by the utmost point and connecing, make the cross-sectional area of groove decay step by step to gas vent between the groove, i.e. series system also by the gas access; Strip-shaped grooves account for entire working surface long-pending 1/2～4/5.
In addition, demarcation strip and baffler best incorporated are one among the present invention.
Bipolar plates provided by the present invention can have following two kinds of concrete forms:
One, first group of 8 parallel connection of the strip-shaped grooves on the baffler, second group of 4 parallel connection, the 3rd group of 2 parallel connections are connected between three groups.
Two, first group of 4 parallel connection of the strip-shaped grooves on the baffler, second group of 2 parallel connection connected between two groups.
In a word, the present invention has following characteristics:
1. the present invention carries out the distribution of reaction gas with the also series system of gas passage on the flow-field plate of bipolar plates both sides, makes electrode surface all can obtain enough gas supplies everywhere.
Because and the enforcement of the air flue of connecting, make electrode everywhere air-flow all be in turbulence state, promoted the carrying out of electrode surface mass transfer, improved the performance of battery.
3. because the present invention has promoted making full use of of reaction gas, reduce exhaust emissions, saved the supply of reaction gas, improved the utilance of reaction gas.
4. also the design of the air flue of series connection makes the speed of gas in passage consistently, and the turbulent flow that continues has promoted the discharge of oxidant side water.
5. adopt line cutting or electric spark method processing flow-field plate passage, battery processing is produced in enormous quantities, manufacturing expense reduces.
