Description
Technical field
The present invention relates to fuel cell, relate in particular to a kind of double-fuel cell dynamical system that can run parallel.
Background technology
Electrochemical fuel cell is a kind of device that hydrogen and oxidant can be changed into electric energy and product.The internal core parts of this device are membrane electrode (Membrane Electrode Assembly are called for short MEA), and membrane electrode (MEA) is made up of as carbon paper a proton exchange membrane, two porous conductive materials of film two sides folder.The catalyst that contains the initiation electrochemical reaction of even tiny dispersion on two boundary faces of film and carbon paper is as the metal platinum catalyst.The membrane electrode both sides can electrochemistry will take place with conductive body to be sent out and answers the electronics that generates in the process, draws by external circuit, constitutes current circuit.
At the anode tap of membrane electrode, fuel can pass porousness diffusion material (carbon paper) by infiltration, and electrochemical reaction takes place on catalyst surface, lose electronics, form cation, cation can pass proton exchange membrane by migration, arrives the other end cathode terminal of membrane electrode.At the cathode terminal of membrane electrode, contain the gas of oxidant (as oxygen), as air, pass porousness diffusion material (carbon paper), and the generation electrochemical reaction obtains electronics on catalyst surface, forms anion by infiltration.The cation of coming in the anion and the anode tap migration of cathode terminal formation reacts, and forms product.
Adopting hydrogen is fuel, and the air that contains oxygen is in the Proton Exchange Membrane Fuel Cells of oxidant (or pure oxygen is an oxidant), and fuel hydrogen has just produced hydrogen cation (or being proton) in the catalytic electrochemical reaction of anode region.Proton exchange membrane helps the hydrogen cation to move to the cathodic region from the anode region.In addition, proton exchange membrane is separated the air-flow and the oxygen containing air-flow of hydrogen fuel, they can not mixed mutually and produces explosion type reaction.
In the cathodic region, oxygen obtains electronics on catalyst surface, forms anion, and moves the hydrogen cation reaction of coming, reaction of formation product water with the anode region.In the Proton Exchange Membrane Fuel Cells that adopts hydrogen, air (oxygen), anode reaction and cathode reaction can be expressed in order to following equation:
Anode reaction: H
2→ 2H
++ 2e
Cathode reaction: 1/2O
2+ 2H
++ 2e → H
2O
In typical Proton Exchange Membrane Fuel Cells, membrane electrode (MEA) generally all is placed in the middle of the pole plate of two conductions, and quarter is milled by die casting, punching press or machinery in the surface that every guide plate contacts with membrane electrode, and formation is the guiding gutter of one or more at least.These guide plates can above metal material pole plate, also can be the pole plate of graphite material.Fluid duct on these guide plates and guiding gutter import fuel and oxidant the anode region and the cathodic region on membrane electrode both sides respectively.In the structure of a Proton Exchange Membrane Fuel Cells monocell, only there is a membrane electrode, the membrane electrode both sides are respectively the baffler of anode fuel and the baffler of cathode oxidant.These bafflers are both as current collector plate, and also as the mechanical support on membrane electrode both sides, the guiding gutter on the baffler acts as a fuel again and enters the passage of anode, cathode surface with oxidant, and as the passage of taking away the water that generates in the fuel cell operation process.
In order to increase the gross power of whole Proton Exchange Membrane Fuel Cells, two or more monocells can be connected into battery pack or be unified into battery pack by the mode that tiles usually by straight folded mode.In straight folded, in-line battery pack, can there be guiding gutter on the two sides of a pole plate, and wherein one side can be used as the anode guide face of a membrane electrode, and another side can be used as the cathode diversion face of another adjacent membranes electrode, and this pole plate is called bipolar plates.A series of monocell connects together by certain way and forms a battery pack.Battery pack tightens together by front end-plate, end plate and pull bar usually and becomes one.
A typical battery stack generally includes: the water conservancy diversion import and the flow-guiding channel of (1) fuel and oxidant gas are distributed to fuel (hydrogen-rich gas that obtains as hydrogen, methyl alcohol or methyl alcohol, natural gas, gasoline) and oxidant (mainly being oxygen or air) in the guiding gutter of each anode, cathode plane equably after reforming; (2) import and export and the flow-guiding channel of cooling fluid (as water) are evenly distributed to cooling fluid in each battery pack inner cooling channel, and the heat absorption that hydrogen in the fuel cell, the exothermic reaction of oxygen electrochemistry are generated is also taken battery pack out of and dispelled the heat; (3) outlet of fuel and oxidant gas and corresponding flow-guiding channel, fuel gas and oxidant gas are when discharging, and portability goes out the liquid that generates in the fuel cell, the water of steam state.Usually, the import and export of all fuel, oxidant, cooling fluid are all opened on the end plate of fuel battery or on two end plates.
Proton Exchange Membrane Fuel Cells can be used as the dynamical system of delivery vehicles such as car, ship, can be used as movable type, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT) again.
When used in proton exchange membrane fuel cell is done car, ship power system or movable type and stationary power generation station, must comprise battery pile, fuel hydrogen supply subsystem, air supply subsystem, cooling heat dissipation subsystem, control and electric energy output various piece automatically.
Fig. 1 is a fuel cell generation, and 1 is fuel cell pack in Fig. 1; 2 are storage hydrogen bottle or other hydrogen-storing devices; 3 is pressure-reducing valve; 4 is air filter; 5 is the air compression feeding mechanism; 6 is the hydrogen Water-vapor seperator; 6 ' is the air Water-vapor seperator; 7 is water tank; 8 is the cooling fluid circulating pump; 9 is radiator; 10 is the hydrogen circulating pump.
At present, fuel cell generation is used for the dynamical system of delivery vehicle or as the power station, all requires very high power output.This high power output is embodied in fuel cell pack and necessarily requires high voltage, big electric current output.
In practical application, powerful fuel cell pack all is to be realized through the method that integration mode constitutes on the volume compact big fuel cell pack by a plurality of fuel battery stack modules.
For example the method for " US Patent 5486430 " is arranged in parallel a plurality of fuel cell packs, and unified being integrated on the shared front console carried out in the import of all air of each fuel cell pack, hydrogen, cooling water, outlet.The six shared big fluid passages of import and export that all air on all fuel cell packs, hydrogen, cooling water are arranged on the front console.The described method of the patent of Shenli Science and Technology Co Ltd, Shanghai " a kind of fuel cell of integrated form (patent No.: 02265512.3) " for example again, by the shared current-collecting panel of a plurality of fuel cell packs, the forward and backward integrated a plurality of fuel cell packs on this current-collecting panel.This current-collecting panel is equivalent to the centre at a plurality of fuel cell packs, and the import and export of the air of all fuel cell packs, hydrogen, cooling fluid is all unified to be integrated on the shared current-collecting panel of this piece.The six shared big fluid passages of import and export that all air on all fuel cell packs, hydrogen, cooling fluid are arranged on this current-collecting panel.
The above-mentioned integral type fuel battery of realizing by the whole bag of tricks, though shared each fluid passage of each fuel battery stack module, but each module all has the positive and negative flow-collection mother-board of oneself, connect by the positive and negative electrode motherboard on all fuel cell modules being carried out series and parallel, whole integral type fuel battery can be exported the high voltage that corresponds to actual needs, the requirement of big electric current.
Fuel cell generation to more high-power output, can pass through integrated more fuel battery stack module in principle, and allowing the import and export shared six big fluid passages of all air on all fuel battery stack modules, hydrogen, cooling fluid, the big fuel cell pack after promptly integrated is a kind of integral structure with six big fluid lines of total air, hydrogen, cooling fluid import and export equally.
But fuel cell generation to super high power output, for example: more than 100KW, even the fuel cell generation of output more than hundreds of kilowatts, need integrated fuel battery stack module quantity too many, so many fuel battery stack modules are integrated the integral type fuel battery of becoming one structure, no matter be to adopt which kind of integrated approach, difficulty all is very large, even it is impossible to say so from engineering.
