Description
Technical field
The utility model relates to the accessory equipment of fuel cell, relates in particular to a kind of device that utilizes automotive operation to improve fuel battery engine performance.
Background technology
Electrochemical fuel cell is a kind of device that hydrogen fuel and oxidizer can be changed into electric energy and resultant of reaction.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 PEM, two porous conductive materials of film two sides folder.The catalyst that contains the initiation electrochemical reaction of even tiny dispersion on two boundary surfaces of film and carbon paper is as the metal platinum catalyst.The electronics that the membrane electrode both sides can will take place to generate in the electrochemical reaction process with conductive body is drawn by external circuit, constitutes current return.
At the anode tap of membrane electrode, fuel can pass porosity diffusion material (carbon paper) by infiltration, and electrochemical reaction takes place on catalyst surface, lose electronics, form positive ion, positive ion can pass PEM by migration, arrives the other end cathode terminal of membrane electrode.At the cathode terminal of membrane electrode, contain the gas of oxidizer (as oxygen), as air, pass porosity diffusion material (carbon paper), and the generation electrochemical reaction obtains electronics on catalyst surface, forms negative ion by infiltration.The positive ion of coming in the anion and the anode tap migration of cathode terminal formation reacts, and forms resultant of reaction.
Adopting hydrogen is fuel, and the air that contains oxygen is in the Proton Exchange Membrane Fuel Cells of oxidizer (or pure oxygen is an oxidizer), and fuel hydrogen has just produced hydrogen positive ion (or being proton) in the catalytic electrochemical reaction of positive column.PEM helps the hydrogen positive ion to move to cathode region from the positive column.In addition, PEM is separated the air-flow and the oxygen air-flow of hydrogen fuel, they can not mixed mutually and produces explosive type reaction.
At cathode region, oxygen obtains electronics on catalyst surface, forms negative ion, and moves the hydrogen positive ion reaction of coming, reaction of formation product water with the positive column.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 the representative type Proton Exchange Membrane Fuel Cells, membrane electrode (MEA) generally all is placed in the middle of the pole plate of two conductions, leads the surface that the membrane electrode plate contacts with membrane electrode for every and mills quarter by die casting, punching press or machinery, forms the flame diversion trough of one or more at least.These lead the pole plate that the membrane electrode plate can be a metallic material, also can be the pole plates of graphite material.These lead positive column and cathode region that water conservancy diversion duct on the membrane electrode plate and flame diversion trough import fuel and oxidizer the 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, flame diversion trough on the guide plate acts as a fuel again and enters the passage of anode, cathode surface with oxidizer, and as the passage of taking away the water that generates in the fuel cell operation process.
In order to increase the gross horsepower 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 flame diversion trough 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, lower back panel 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 (as hydrogen, methyl alcohol or the hydrogen-rich gas that obtained by methyl alcohol, natural fuels, gasoline) and oxidizer (mainly being oxygen or air) in the flame diversion trough 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, the heat absorption that hydrogen in the fuel cell, the exothermal reaction of oxygen electrochemistry are generated and take battery pack out of after dispel 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, oxidizer, cooling fluid are all opened on the end plate of fuel cells or on two end plates.
Proton Exchange Membrane Fuel Cells can be used as the power system of means of deliverys such as all cars, ship, can make hand-held design, movable type, fixed power generation assembly again.
Proton Exchange Membrane Fuel Cells is generally with hydrogen or contain portly hydrogen or alcohols is made fuel.As car, ship power system or movable type, stationary power generation station the time, generally use air oxidant.
When used in proton exchange membrane fuel cell is done car, ship power system or movable type, stationary power generation station, must comprise battery pile, fuel supply, air supply, cooling heat dissipation, automatic guidance and electric energy output various piece.Wherein air supply is essential.Electrochemical reaction in the Proton Exchange Membrane Fuel Cells improves along with the pressure of fuel, oxidizer air and accelerates.
Automobile is in operational process, headstock part can form powerful air positive pressure, if air filter is not arranged on this position, will cause the waste of the energy, and the offgas duct operated by rotary motion is at car chassis, when driving is very fast, can form vacuum at the bottom of the car, if offgas duct is vertical with direction of traffic or identically just can't reach exhaust effect, if angled, exhaust effect is not good yet.
