Technical field
The present invention relates to fuel cell, relate in particular to a kind of fuel cell that under the situation that power output increases suddenly, can respond fast.
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 Proton Exchange Membrane Fuel Cells can be used as car, ship power system or movable type and stationary power generation station, must comprise battery pile, fuel hydrogen supply system, 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, and 2 are storage hydrogen bottle or other hydrogen-storing devices, and 3 is pressure-reducing valve, and 4 is air filter, and 5 is the air compression feeding mechanism; 6 ', 6 is Water-vapor seperator, and 7 is water tank, and 8 is the cooling fluid circulating pump, and 9 is radiator, and 10 is the hydrogen circulating pump, and 11,12 is humidifying device.
According to the principle or the principle of typical above-mentioned fuel cell generation operation at present, the patent of invention of Shenli Science and Technology Co Ltd, Shanghai " a kind of fuel cell that has device for controlling dynamically " for example, Chinese patent application number is 200410016609.4; 200420020471.0.Controller in the fuel cell generation, by temperature of fuel cell, power output demand are monitored and are calculated, determine control, fuel cell pack is realized under the power condition that any power output requires: 1. the related control of power output and working temperature hydrogen flowing quantity, air mass flow; 2. the related control of power output and hydrogen flowing quantity, air mass flow, wherein hydrogen flowing quantity with air mass flow by the demanded power output metering than being 1.2,2.0 controls respectively; 3. hydrogen flowing quantity and air mass flow link with the humidifying device that can realize dynamic humidification adjusting control accordingly respectively and dynamically control, and make hydrogen, air under any flow that enters in the fuel cell pack all keep best relative humidity (a certain numerical value in the middle of 70%～95%); 4. according to the situation of extraneous weather temperature and humidity, regulate and control method (3) point together, and reach and the identical purpose of (3) point.Final purpose is to make fuel cell pack realize high-effect operation and move that fuel cell pack can have best fuel efficiency under best operating condition under the power condition that any power output requires.
The principle of the dynamic control of above-mentioned fuel cell generation and principle, realize operational factor exactly according to fuel cell, require etc. to monitor automatically and to calculate in different working temperatures, environment, power output, and control by the target setting value and to reach fuel cell in best operating condition and high efficiency operation.
The wherein related control of power output and hydrogen flowing quantity, air mass flow, hydrogen flowing quantity are pressed the demanded power output metering than 1.2; It is more extremely important than 2.0～2.5 controls that air mass flow is pressed the demanded power output metering, otherwise long-play under the hydrogen of excessive flow, air regime, whole fuel cell generation overall efficiency is reduced, also can make the fuel cell operation condition be in abnormal state, serious situation can make fuel battery performance reduce, or even irreversibly performance loss.
Though the control of the dynamic object of above-mentioned fuel cell generation can be guaranteed whole fuel cell long-play, and can reach and be in the high efficiency state but when fuel cell generation uses as the dynamical system on the various delivery vehicles, or as movable type, when use in the distributing power station, the situation that all can require fuel cell output power to increase suddenly.For example, when fuel cell electric vehicle starting, quicken, or climbing, or during the power supply of fuel cell power generation station, the user increases situations such as some powerful loads suddenly, all can cause the situation that requires fuel cell output power to increase suddenly.
The fuel cell power generation principle is actually in the fuel cell hydrogen fuel and generates water with supply airborne oxygen chemical combination to fuel cell, and this chemical reaction process is the process that most of chemical energy changes into electric energy.So the speed of fuel cell power generation is subjected to the influence of many factors:
(1) to the speed and the adequacy of fuel cell supply hydrogen fuel, air;
(2) speed of hydrogen, the electrode diffusion of airborne oxygen in fuel cell;
(3) hydrogen, the airborne oxygen catalytic reaction speed in electrode;
Wherein (2), (3) point designs relevant with the generating capacity of fuel cell itself.
In general, when situations such as fuel cell electric vehicle sudden startup, acceleration occurring, or during the situations such as user's loading suddenly of fuel cell power generation station supply, the response speed that requires fuel cell output power is very fast.
The fuel cell generation of design has following serious technological deficiency now:
Though the promptly generating capacity of the design of fuel cell rated output power own generally all can satisfy as vehicle-mounted power source, or the requirement of power station maximum power requirement, but fuel cell is as vehicle-mounted power source, or during the power station, from idling mode or low power demand, be increased to high-power suddenly even maximum power requirement is recurrent.The principle and the principle of the dynamic control of present fuel cell generation, realize operational factor exactly according to fuel cell, require etc. to monitor automatically and to calculate in different working temperatures, environment, power output, and control by the target setting value and to reach fuel cell high efficiency operation under best operating condition.The wherein related control of power output and hydrogen flowing quantity, air mass flow, hydrogen flowing quantity are pressed the demanded power output metering than 1.2; Air mass flow is pressed the demanded power output metering than 2.0～2.5 controls.The related control of power output and air mass flow generally is the power demand size according to external circuit, and the motor speed that calculates and regulate air transport device reaches the adjusting air mass flow, and makes air mass flow reach 2.0～2.5 target control requirement.
That is to say when external circuit requirement fuel cell output power increases suddenly, air transport device in the necessary first fuel metering battery generating system of fuel cell generation, as the motor speed in air compressor machine, the air blast, motor speed is accelerated greatly, with the flow of increase air, and reach the air mass flow requirement that increases power output to the fuel cell pack conveying.
In general, electric machine speed regulation needs the time, and particularly motor often needs the 0.5-1 second even the longer time interval when low speed is adjusted to high speed.But when fuel cell electric vehicle is in situations such as sudden startup, acceleration, or situation such as the user of fuel cell power generation station supply loading suddenly is when occurring, just require the response speed of fuel cell output power very fast, the time interval is less than 0.5 second often greatly.
Air transports not as good as response so fuel cell generation can appear in above-mentioned situation, and causes whole fuel cell generation can't respond the power demand that output increases suddenly fast, and when serious, whole fuel cell generation can cause collapse.
