Description
Technical field
The present invention relates to fuel cell, relate in particular to a kind of assembly method of fluid distributing board and current collecting master board of fuel cell.
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 guide plate of anode fuel and the guide plate of cathode oxidant.These guide plates are both as current collector plate, also as the mechanical support on membrane electrode both sides, guiding gutter on the guide plate 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 both can be used as the dynamical system of delivery vehicles such as car, ship, can be used as movable type or stationary power generation station again.
Proton Exchange Membrane Fuel Cells generally is made up of several monocells, these monocells are coupled together the formation pem fuel cell stack in the mode of serial or parallel connection, and pem fuel cell stack and other operation back-up systems are combined constitutes whole Proton Exchange Membrane Fuel Cells electricity generation system.
As Fig. 1 is the membrane electrode that has now in the Proton Exchange Membrane Fuel Cells monocell, and it comprises air inlet 1a, water inlet 2a, hydrogen inlet 3a, electrode activity zone 4a, air gas outlet 5a, delivery port 6a, hydrogen gas outlet 7a; As Fig. 2 is the guide plate that has now in the Proton Exchange Membrane Fuel Cells monocell, and it comprises air inlet 1a, water inlet 2a, hydrogen inlet 3a, runner 8a, air gas outlet 5a, delivery port 6a, hydrogen gas outlet 7a; As Fig. 3 is the fuel cell pack that a kind of several monocells connect with series system, and it comprises panel 9a, the first current collecting master board 10a, battery pile 11a, the second current collecting master board 12a, load 13a; Pem fuel cell stack can be made up of several monocell series systems, also can several monocell series connection constitute a unit, again several this unit are constituted fuel cell pack as Fig. 4 with parallel form, this fuel cell pack comprises the first current collecting master board 10a, battery pile 11a, the second current collecting master board 12a, insulation board 14a; The pem fuel cell stack of above Fig. 3, Fig. 4 indication all relates to two or polylith current collecting master board, is respectively the positive and negative or negative, positive current collecting master board in the fuel cell pack.These two current collecting master boards have following two kinds of effects:
1, the fuel-cell single-cell of several serial or parallel connections or the electric current of whole fuel cell pack are extracted, constitute the positive and negative electrode of conducting external current;
2, hole, various fluids road is also arranged on the current collecting master board, can allow the various fluids of fuel cell freely pass through, the same size with pod apertures on the guide plate of this fluid bore, current collecting master board size are identical with guide plate size in the fuel cell pack basically.
Current collecting master board in the present various fuel cell pack all adopts very special material in order to reach above two kinds of effects, for example, and metallic gold, metal platinum or adopt other metals such as the method for stainless steel, copper, aluminium, gold-plated, platinum.Adopt these materials, electric conductivity is very good, and at various fluids the electrochemical corrosion reaction can not take place during by current collecting master board and produces the metal ion that fuel cell is endangered.But these materials are very expensive as noble metals such as gold, platinum, electroplate on materials such as other metallic coppers, stainless steel, aluminium, and price is also more expensive, and inconvenient.
