Description
Technical field
The present invention relates to fuel cell, relate in particular to the humidity temperature pickup that is applied to fuel cell.
Background technology
Electrochemical fuel cell is a kind of device that hydrogen and oxygenant can be changed into electric energy and reaction 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 PEM, two porous conductive materials of film two sides folder.The catalyzer that contains the initiation electrochemical reaction of even tiny dispersion on two boundary surfaces of film and carbon paper is as the metal platinum catalyzer.The membrane electrode both sides can galvanochemistry 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 return.
At the anode tap of membrane electrode, fuel can pass poriness 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 oxygenant (as oxygen), as air, pass poriness 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 negative ion and the anode tap migration of cathode terminal formation reacts, and forms reaction product.
Adopting hydrogen is fuel, and the air that contains oxygen is in the Proton Exchange Membrane Fuel Cells of oxygenant (or pure oxygen is an oxygenant), and fuel hydrogen has just produced hydrogen positive ion (or being proton) in the catalytic electrochemical reaction of anodic site.PEM helps the hydrogen positive ion to move to the cathodic area from the anodic site.In addition, PEM 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 area, 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 anodic site.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 diversion trench 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 diversion trench import fuel and oxygenant the anodic site and the cathodic area 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 fair water fin of anode fuel and the fair water fin of cathode oxidant.These fair water fins are both as current collector plate, and also as the mechanical support on membrane electrode both sides, the diversion trench on the fair water fin acts as a fuel again and enters the passage of anode, cathode surface with oxygenant, and as the passage of taking away the water that generates in the fuel cell operation process.
In order to increase the general power of whole Proton Exchange Membrane Fuel Cells, two or more monocells can be connected into electric battery or be unified into electric battery by the mode that tiles usually by straight folded mode.In straight folded, in-line electric battery, can there be diversion trench 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 an electric battery.Electric battery 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, rock gas, gasoline) and oxygenant (mainly being oxygen or air) in the diversion trench 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 electric battery inner cooling channel, and the thermal absorption that hydrogen in the fuel cell, the themopositive reaction of oxygen galvanochemistry are generated is also taken electric battery 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, oxygenant, cooling fluid are all opened on the end plate of fuel cell group or on two end plates.
Proton Exchange Membrane Fuel Cells can be used as the power system of delivery vehicles such as all cars, ship, also can be used as portable, portable, fixed Blast Furnace Top Gas Recovery Turbine Unit (TRT).
All must guarantee the stability of fuel cell long-time running when at present, fuel cell generation is as car, ship power system or movable type, stationary power generation station.
In order to guarantee the stability of fuel cell long-time running, used PEM in the present membrane electrode of fuel batter with proton exchange film, needing the hydrone existence in the battery operation process preserves moisture, because have only the proton of aquation just can freely pass PEM, arrive the electrode cathode end from the electrode anode end and participate in electrochemical reaction.Otherwise, when the air of a large amount of dryings or hydrogen to the fuel cell supply and when leaving fuel cell, easily the moisture subband in the PEM is run, proton can't pass PEM, causes the electrode internal resistance sharply to increase, battery performance sharply descends.So in general hydrogen or air to the fuel cell supply need through humidification, the hydrogen or the relative air humidity that enter fuel cell are improved, in order to avoid make the PEM dehydration.
At present, the humidifying device that is applied to Proton Exchange Membrane Fuel Cells mainly contains two kinds:
1. before dry hydrogen gas or air and pure water enter fuel cell, the gaseous air, the hydrone that in humidifying device, carry out hydrone and hydrogen or air molecule being after the direct collision and mix, after the steam separation, when entering fuel cell, be hydrogen or the air that reaches certain relative humidity.
2. dry hydrogen gas or air directly do not contact at humidifying device before entering fuel cell with pure water, but can allow hydrone freely see through but the film that do not allow gas molecule see through is separated by one deck, when film flows through dry hydrogen gas or air on one side and film another side when flowing through pure water, hydrone will see through the another side of film automatically from one side of film, make air molecule mix the air of the relative humidity that reaches certain with hydrone.This film can be a PEM, as Nafion film of E.I.Du Pont Company etc.
When fuel cell generation was used as car, ship power system or movable type, stationary power generation station, output power generally all must change with the variation of driving employee's condition conditioned disjunction user power utilization situation; During in particular as car, ship power system, working conditions change can be very frequent, and car, ship be in idling mode to the starting acceleration mode working conditions change the time, corresponding requirements fuel cell generation output power from very little change to immediately very big.
The variation of fuel cell generation output power, requirement also changes to the flow of fuel cell supplied fuel hydrogen, air, cooling fluid, adapt to the requirement that fuel battery power output changes to satisfy, and improve the generating efficiency of fuel cell generation self.
Because fuel cell generation back-up system operation generating itself also must consume certain power.Wherein, the main power component that consumes has: 1. the conveying device of carrying air to fuel cell pack; 2. hydrogen ebullator; 3. cooling fluid circulation discharge pump; More 4. with the relevant parts of automatic control, as controller; Control executive component is as solenoid valve, radiator fan etc.
These account for 10～20% of whole fuel cell pack gross output from all consumed powers of consumed power parts.So,, when the fuel cell generation output power alters a great deal, also require to support the power consumption device generation dynamic response of fuel cell generation operation itself in principle in order to improve the generating efficiency of whole fuel cell generation.The device bigger to some power consumptions, as: air discharge pump, hydrogen ebullator, cooling fluid ebullator etc. are realized dynamically control.In general, when under fuel cell generation is at full capacity rated power output operating mode, working, the power consumption device that above-mentioned three is bigger also is in maximum power dissipation rating duty, be in very miniwatt output and work as fuel cell generation, even be in and await orders or idling operation down during work, motor in the bigger power consumption device of above-mentioned three is carried out speed governing, reduce to its consumed power minimum.
So, when fuel cell generation changes in output power, require to change, to satisfy the requirement that output power changes to the flow of fuel cell supplied fuel hydrogen, air, cooling fluid.But two kinds of humidifying device technology in the existing fuel cell generation realize that between above-mentioned flow to fuel cell generation supplied fuel hydrogen, air, cooling fluid and the output power following technological deficiency is arranged in the related dynamic response control:
1. the humidifying device of above-mentioned two kinds of technology generally all press the nominal operation temperature under the fuel cell generation nominal operation state, and air, hydrogen flowing quantity accordingly; Pressure, cooling fluid flow parameter and the humidifying device that is designed to, can make fuel cell generation stable work under specified operating point for a long time, and corresponding air, hydrogen flowing quantity and working pressure can be worked under just suitable fuel cell rated condition by this humidifying device humidification, wherein relative humidity is greatly about 70～95%, and is very appropriate to the high-effect operation and the life-saving of fuel cell.
But it is less to work as the fuel cell generation output power, or when being in idling mode, require less this moment to the flow of fuel cell supplied fuel hydrogen, air, cooling fluid, the fuel hydrogen of low discharge and air often caused humidification (relative humidity reaches 100%) easily through bigger fixed humidifying device like this, the easy so inner ponding of fuel cell pack that causes.
2. it is bigger to work as the fuel cell generation output power, even is in when exceeding the quata in short-term to decide the peak power output of power, requires this moment to reach maximum to the flow of fuel cell supplied fuel hydrogen, air, cooling fluid.The hydrogen of the big flow that this and peak power is complementary and air often cause humidification not enough through fixed humidifying device, promptly can't reach predetermined relative humidity.
3. humidifying device reaches predetermined working temperature by the used heat of fuel cell often, if when fuel cell generation does not reach the nominal operation temperature as yet (about 70 ℃), this moment, the working temperature of humidifying device did not often reach the nominal operation temperature yet.In general, humidifying device is not only relevant with the engineering design of this humidifying device to the humidification degree of hydrogen, air, and relevant with working temperature, and working temperature is high more, and the humidification degree is high more.So when fuel cell generation reaches the nominal operation temperature far away, often cause hydrogen, air mass flow humidification original and that rated power is complementary not enough, promptly can't reach the requirement of specified relative humidity.
4. the humidification degree of air and atmospheric environment temperature and humidity also have certain relation.In general, at the temperature height, under the weather condition of high humidity, during the humidifying device of air process said fixing formula, caused humidification easily; And low at temperature, under the little weather condition of humidity, air can cause humidification not enough during through the humidifying device of said fixing formula.And the air humidity that enters pile with the humidification rotating speed of motor be not line capable and relation one to one.
The humidifying device of above-mentioned two kinds of technology is fixed, can't realize dynamic humidification adjusting to the current intelligence that some fuel cell generations occur.So can cause fuel cell pack often to be in or the mistake humidification, otherwise the not enough state of humidification, and these unfavoured states can have a strong impact on the usefulness of fuel cell pack, even cause performance seriously to decay, influence the life-span.
In order to overcome above-mentioned technological deficiency, (the application for a patent for invention number: 200410016609.4 of a kind of fuel cell that has a device for controlling dynamically has been invented by Shenli Science and Technology Co Ltd, Shanghai, utility application number: 400420020471.0), this fuel cell comprises fuel cell pack 1, hydrogen cylinder 2, reduction valve 3, air strainer 4, air compression supplying device 5, Water-vapor seperator 6,6 ', water tank 7, water pump 8, heating radiator 9, hydrogen ebullator 10, hydrogen road high effect humidifying device 11, air road high effect humidifying device 12, hydrogen road humidifying device adjustable speed motor 13, air road humidifying device adjustable speed motor 13 '; It is characterized in that, comprise that also the hydrogen road advances fuel cell pack hydrogen relative humidity sensor 14, fuel cell pack hydrogen temperature sensor 15 is advanced on the hydrogen road, fuel cell pack relative air humidity sensor 16 is advanced on the air road, fuel cell pack air temperature sensor 17 is advanced on the air road, and fuel cell pack cooling fluid temperature sensor 18 is advanced on the cooling fluid road; Described hydrogen road high effect humidifying device 11, air road high effect humidifying device 12 can dynamically be controlled the humidification degree of air, hydrogen.By hydrogen relative humidity sensor 14, temperature sensor 15 is surveyed the hydrogen road and is advanced fuel cell pack hydrogen relative temperature humidity, be installed in the rotary humidifier 11 that can dynamically control the humidification degree in the hydrogen road, can drive the rotation of humidifier inner bag by the brushless electric machine of speed governing, frequency modulation, reach the purpose of regulating hydrogen humidification degree; By relative air humidity sensor 16, fuel cell pack air relative temperature humidity is advanced on temperature sensor 17 detecting air roads, be installed in the rotary humidifier 12 that can dynamically control the humidification degree in the air road, brushless electric machine by can frequency-adjustable speed-adjustable drives the rotation of humidifier inner bag, reach the purpose of regulating the air humidification degree, this invention makes fuel cell can both realize high-effect operation and move under best operating condition under the operating mode that any power output requires.But for temperature how to control fuel cell and humidity and how to implement but not do specific descriptions.
