Technical field
The present invention relates to portable fuel cell system.Be particularly related to the hydrogen-feeding system of fuel cell.
Background technology
Fuel cell (Fuel Cell, FC) be a kind of normal temperature (0～80 ℃) down just can be directly be stored in fuel and the oxidant chemical energy efficiently (50～80%), contamination-freely be converted into the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of electric energy, can be counted as a kind of prime mover that does not have combustion process.The electricity generating principle of FC is the same with chemical power source, and electrode provides the place of electron transfer, and the reaction of anode-catalyzed fuel is just as the oxidizing process of hydrogen, and the reaction of cathode catalysis oxidant is just as the reduction process of oxygen; Conductive ion moves in the electrolyte that anode and cathode is separated, and electronics is by the external circuit work done and constitute electric loop.
Kinds of fuel cells is various, comprise alkaline fuel cell, Proton Exchange Membrane Fuel Cells, direct methanol fuel cell, phosphoric acid fuel cell, molten carbonate fuel cell, Solid Oxide Fuel Cell (SOFC) or the like, in these fuel cells, the type that development potentiality is arranged most is a Proton Exchange Membrane Fuel Cells, it has many characteristics: as replacing rechargeable battery, be the desirable energy of automobile and domestic. applications; Can under lower temperature, work, can under severe cold condition, start rapidly; Power density is higher, so volume is less relatively; Operating efficiency is very high, and can be apace changes its output according to the demand of electricity consumption.The present invention is exactly a kind of portable fuel cell system of creating at Proton Exchange Membrane Fuel Cells.
The hydrogen source of giving the Proton Exchange Membrane Fuel Cells hydrogen supply is methyl alcohol, high-pressure gaseous hydrogen, low temperature liquid hydrogen etc. often, uses these traditional hydrogen sources to occur the flow process complexity often, and it is uncontrollable to produce hydrogen speed, uses and carry problem such as inconvenience.Wherein, use the method for methyl alcohol hydrogen supply to be known as direct methanol fuel cell again.This direct methanol fuel cell is no longer extracted hydrogen and is acted as a fuel from methyl alcohol, but directly make fuel with liquid methanol, though as the power supply of the mobile electronic equipment potentiality that grow a lot, also exist the power of battery low, can only be used for little power consumption and the medium shortcoming of equipment stably.
Summary of the invention:
The flow process complexity appears in the present invention when using these traditional hydrogen sources in order to solve in the fuel cell, it is uncontrollable to produce hydrogen speed, use and carry problems such as inconvenience, the hydrogen that produces with the sodium borohydride hydrolysis is hydrogen source, supply with the ion-exchange membrane fuel cell pile and act as a fuel, produce electric energy by the generating of ion-exchange membrane fuel cell pile.
The hydrolysis of sodium borohydride is as follows:
NaBH4+2H2O→4H2+NaBO2
Sodium borohydride is to be the high hydrogeneous chemical hydride that raw material is made by the natural minerals borax, and the liquid hydrogen storage material of water-soluble formation does not have the danger of spontaneous combustion, blast.Sodium borohydride is more stable in air, can emit whole hydrogen rapidly by catalytic hydrolysis reaction under normal temperature and low temperature, and start-up time is short.Minimum hydrogen discharging temperature can reach-40 ℃.Because the hydroboron hydrolysis is exothermic reaction,,, thereby improve hydrogen discharging speed with automatic heating fuel along with the carrying out of reaction.But produce the boiling point (100 ℃) that the hydrogen temperature can not be higher than water, the hydrogen source of the battery that is very suitable in adverse circumstances, acting as a fuel.The hydrogen that is discharged does not contain impurity such as carbon monoxide, only contains small amount of moisture, is a kind of purified hydrogen that does not need extra humidification, can directly supply with the ion-exchange membrane fuel cell pile and act as a fuel.Fuel after the use can be undertaken recycling by regeneration, can not damage environment.
Compare with the upgrading of traditional chemical hydride (methane, methyl alcohol etc.), sodium borohydride product hydrogen flow process is simple, and system is simple, produces the hydrogen adjustable-speed, and product hydrogen temperature range is wide, and can produce hydrogen under low-temperature condition.Can adopt the method for loading and unloading fuel cassette, prolong the operating time of fuel cell greatly., can use water sources such as seawater, river, stream, snow-broth to produce the raw material of hydrogen in the open air, under extreme case even can use urine as the water source as the sodium borohydride hydrolysis.So sodium borohydride is a kind of field that is particularly suitable for, under the extreme rugged environment, also can be the desirable hydrogen storage media of fuel cell hydrogen-feeding.
The present invention can realize powering mode as required, and hydrogen-feeding system and fuel cell are separable, as far as possible miniaturization.
The fuel cell system that the present invention relates to is applicable to small hydropower station, portable portable power source, outdoor leisure, field work, robot, electric bicycle, electric wheel-chair vehicle and emergency power supply etc.
The fuel cell system that the present invention relates to comprises following components: sodium borohydride hydrogen generation systems, direct current stabilizer, dc-to-ac inverter, ion-exchange membrane fuel cell pile, blower fan and switch, pipeline and valve.By the anode of sodium borohydride hydrogen generation systems generation hydrogen supply ion-exchange membrane fuel cell pile, by the negative electrode of blower fan with airborne oxygen supply ion-exchange membrane fuel cell pile, required power source is in fuel cell pile.Because the negative electrode of pile always contacts with air in stopped status, in case hydrogen enters the anode of pile, thereby pile voltage will raise to reach and starts the required rated voltage of blower fan and drive blower fan.Behind the fan starting, provide more air to enter the pile negative electrode and make pile voltage further raise, thereby make fuel cell reach rated voltage, finish the cold start-up of fuel cell system.
1. sodium borohydride hydrogen generation systems
The sodium borohydride hydrogen generation systems is made up of react device, filter of tanks, hydrogen.
(1) tanks (as shown in Figure 1) is mainly used in the storage sodium borohydride solution, can make the sodium borohydride solution outlet 6 that containscharging aperture 8,trash discharge mouth 5,hydrogen outlet 7, hydrogengeneration product inlet 1 and lead to reactor by nickel plating or plastic coating of fluoride corrosion resistant plate, polyethylene, polypropylene material.The place is provided with gas-liquid separation device at hydrogen generation product inlet, is made up ofbaffle plate 3 and porous material.Baffle plate can be selected nickel plating or plastic coating of fluoride corrosion resistant plate, polyethylene, polypropylene material for use.Tanks and the hydrogen device that reacts is connected by two unidirectional needle-valves.2 is porous material, and the porous material is so long as porous, alkaline-resisting material can.For example porous ceramic, ceramic honey comb, foaming nickel all can be used to do gas-liquid separation, and the aperture is between 0.5-1.5mm.Foaming nickel forms through chemical nickel plating, electronickelling, sintering for foaming polyamine fat.
Gas-liquid separation device is that tanks is built-in, constitute the gas-liquid separation element by nickel foam or porous pottery magnetic, nickel foam or porous ceramic plate are embedded in two U type stainless steel grooved rails that have with nickel foam or porous ceramic plate same thickness, these two U type stainless steel grooved rails are welded to tanks top, constitute gas-liquid separator.Hydrogen outlet is placed in the opposite side top of tanks, does not directly get in touch between gas-liquid separation device and the hydrogen outlet, and hydrogen enters hydrogen outlet by the upper cavity of tanks from gas-liquid separator.
The fuel that adds in the tanks is sodium borohydride, NaOH and water, and the percentage by weight of each composition is sodium borohydride: 5-50%, NaOH: 1-15%, and all the other are water.In the sodium borohydride hydrolytic process, produce kodalk, so system is when in running order, fuel consist of sodium borohydride, NaOH, kodalk and water.The content of kodalk constantly raises along with the carrying out of hydrolysis.The water of hydrolysis is best with the pure water, and impurity content is high more, and the hydrogen quality of generation is poor more.It is in proper order: pure water, running water, stream, seawater, river, beverage, urine.
(2) the hydrogen device (as shown in Figure 2) that reacts is provided with from the sodium borohydride solution import 13 of tanks and theoutlet 10 of hydrogen generation product, and theoutlet 11 of passing through the outside emptying gas of triple valve, be mainly used in outside emptying gas, form pressure differential, impel fuel solution to enter tanks.Reactor can be made by nickel plating or plastic coating of fluoride corrosion resistant plate, polyethylene, polypropylene material.The incorporate porous reaction bed of being made up of the porous Raney'snickel catalyst 12 is housed in the reactor.Be connected to tanks by two unidirectional needle-valve V1 and V2, control the pressure at reactor two ends by the opening degree of valve V1.When holding state, force down in the sodium borohydride solution entrance point in hydrogen generation product outlet pressure, make sodium borohydride solution not enter reactor again and stop the generation of hydrogen.And in working order the time, the interior pressure of sodium borohydridesolution entrance point 13 is higher than the pressure of hydrogen generation product outlet 10.So just can avoid forming the hydrogen adverse current, cause entering of sodium borohydride solution not smooth.
(3) filter (as shown in Figure 3) is provided withhydrogen inlet 16 that connects the tanks top and theoutlet 14 that purifies back hydrogen, and theoutlet 14 of hydrogen is connected with the pipeline of fuel cell air inlet by valve V3.Filter is made by nickel plating or plastic coating of fluoride steel plate or corrosion resistant plate, polyethylene, polypropylene material.Theporous material 15 of three-dimensional through hole is installed in the filter, and porous material is that foaming nickel is to disperse bubble hydrogen.Be filled with the absorbent that absorbs kodalk and NaOH in the filter, absorbent is tartaric acid, phosphoric acid, acetic acid, sulfuric acid or its mixture.Absorbent is mainly used in NaBO2Absorption with NaOH.
The principle of absorbent is the acid-base neutralization reaction, and any in theory acid all can be made absorbent.Consider absorption efficiency, proton content is high more in the acid, and is good more to the assimilation effect of NaBO2 and NaOH, and therefore 3 valencys are good.Divalent acid also can be used for absorbent, and as acetic acid, sulfuric acid etc., 3 valency acid are poor but efficient compares.Also need consider the saturated vapor pressure of acid in addition, the higher acid of vapour pressure also can be brought fuel cell into hydrogen when absorbing entrainment, performance is exerted an influence, so tartaric acid and phosphoric acid is preferable selection.Phosphoric acid is middle strong acid, and tartaric acid is weak acid.The perishable container of strong acid, in case leak the borine that generates severe toxicity easily with the NaBH4 reaction, and weak acid only can be accelerated the hydrolysis of sodium borohydride, even the consequence that leakage can courting disaster property yet takes place.Weak acid is safer, but neutralization reaction speed is lower, a little less than the middle strong acid of assimilation effect is wanted, is good so select the mixture of tartaric acid and phosphoric acid.In case the acidity of absorbent descends, be tending towards neutral, need to change absorbent.
2. ion-exchange membrane fuel cell pile (anode, negative electrode)
The ion-exchange membrane fuel cell pile can be by proton exchange membrane, or anion-exchange membrane (conductive ion is a hydroxide ion) is as ion conductor, can also use cluster ion exchange membrane that proton exchange membrane and anion-exchange membrane form as ion conductor.The ion-exchange membrane fuel cell pile is coated in composite catalyst on the porous carbon paper with hydrophobicity and constitutes electrode and form, and this composite catalyst is to be dispersed in after mixing with platinum, palladium simple substance catalyst or both on the carbon black and the catalyst that constitutes.Between two pieces of electrodes, separate by amberplex, wherein electrode scribbles the face of catalyst towards amberplex, form the membrane electrode integrated constituent element that constitutes the ion-exchange membrane fuel cell pile by hot pressing, the bipolar plates and the membrane electrode that are carved with stream are piled up formation ion-exchange membrane fuel cell pile.When adopting anion-exchange membrane, can use platinum, palladium, silver, nickel and alloy thereof or mixture to be negative electrode or anode catalyst, wherein, cathod catalyst can also use manganese dioxide.Can between the fuel outlet end of fuel cell and tanks, be connectedbooster pump 24, with the defeated tanks of getting back to of the anodic product (residual hydrogen and steam) after the anion-exchange membrane fuel cells generating, to reach the purpose that reclaims hydrogen and water.Hydrogen can generate electricity again, improves the utilance of hydrogen.The water that reclaims can be used to dilute sodium borohydride solution, makes to use the high concentration sodium borohydride solution to become possibility for producing the hydrogen raw material, thereby improves the energy density of fuel cell system.
