Description
Technical field
The present invention relates to fuel cell, relate in particular to a kind of integrated approach with Proton Exchange Membrane Fuel Cells of interior humidifying device.
Background technology
Electrochemical fuel cell is a kind of device that hydrogen fuel 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 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 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 block of flow guiding electrode plate contacts with membrane electrode, and formation is the guiding gutter of one or more at least.These flow guiding electrode plates can be the pole plates of metal material, also can be the pole plates of graphite material.Water conservancy diversion duct on these flow guiding electrode 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 the current collector motherboard, 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 (as hydrogen, methyl alcohol or the hydrogen-rich gas that obtained by 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 water (as water) are evenly distributed to cooling water in each battery pack inner cooling channel, the heat absorption that hydrogen in the fuel cell, the exothermic 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, oxidant, cooling water 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 all cars, ship, can be used as portable, portable, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT) again.Core component is a membrane electrode in the Proton Exchange Membrane Fuel Cells, and proton exchange membrane is the core component in the membrane electrode.
Used proton exchange membrane in the membrane electrode of fuel batter with proton exchange film needs the hydrone existence and preserves moisture in the battery operation process at present.Because have only the proton of aquation just can freely pass proton exchange membrane, arrive the electrode cathode end from the electrode anode end and participate in electrochemical reaction, otherwise, when the fuel hydrogen of a large amount of dryings or air when the membrane electrode both sides are flow through, easily the moisture subband in the proton exchange membrane is run, this moment, proton exchange membrane was in than drying regime, and proton can't pass proton exchange membrane, cause the electrode internal resistance sharply to increase, battery performance sharply descends.So, in general need through humidification to fuel cell supplied fuel hydrogen or air, the fuel hydrogen or the relative air humidity that enter fuel cell are improved, in order to avoid make the proton exchange membrane dehydration.
