Description
Technical field
The utility model relates to fuel cell fields, and in particular to a kind of humidifying technology of fuel cell reaction.
Background technique
Fuel cell be a kind of cleaning, efficiently, the power generator of long-life.Fuel cell and conventional generation technology phase
Than, efficiency, safety, reliability, flexibility, spatter property, in terms of have very big advantage, application prospect is very
It is wide.As one of fuel cell, Proton Exchange Membrane Fuel Cells also has low operation temperature, specific energy height, using the longevity
The advantages that life is long, fast response time and electroless matter leak, national defence, the energy, traffic, environmental protection, in terms of have very
Good application prospect.In Proton Exchange Membrane Fuel Cells operational process, the humid control of cathode inlet (air) is most important
One of link.On the one hand, if air humidity is too low, proton exchange membrane dehydration or withered, the proton conduction of film be will cause
Ability and its water content (wetting state) are in close relations, when film is in good wetting state, just conduct with high proton
Ability, the withered decline that will lead to proton conductivity of film, film resistance increase, and ohmic loss increases, battery performance decline；Together
When machinery strength reduction, will will lead to when serious film rupture, make hydrogen and oxygen mix, explode.On the other hand, if it is empty
Air humidity spends height, will cause that inside battery ponding is excessive, and the catalyst in electrode is caused to be pickled by water, and reactivity reduces, and
And also two-phase flow can be formed in runner and diffusion layer, local obstruction is caused, so that gas transfer process is obstructed, reaction gas
Body is insufficient, causes the output performance of fuel cell to decline, influences battery operation.Therefore, fuel cell reaction gas is wet
Degree control, especially air humidity control are most important in Proton Exchange Membrane Fuel Cells operation, are important controlling unit
One of.
In current practice, for fuel cell air inlet humidification humidifier there are mainly two types of, one is membrane humidifier,
By diffusion couple gas humidification of the moisture in film, another kind is enthalpy wheel humidifier, is humidified by enthalpy wheel.Membrane humidifier has knot
The features such as structure is compact, low pressure drop, typical structure includes wet plate, polymer film and diffusion layer and dry plate, wherein on dry plate
Flow channel is used for circulation and the humidification of dry gas, has humidification channel on wet plate.Membrane material is permeable but airtight, its side with
Wet plate contact, other side are the diffusion layers made of elasticity, conductive, gas permeable material.But there is sealing and hold in membrane humidifier
Pressure problem will lead to and sealing emaciated face because polymer film meets water-swellable, swelling-contraction repeatedly of the film between dry-hygrometric state
From to leak；In addition, polymer film is organic material, it is easily deformable, and voltage endurance capability is poor, in use may be used
It can rupture under the influence of air pressure.
Heating humidification, which refers to, to be humidified by the courteous control bubbler of water temperature by reaction gas, is also known as bubbled humidification；It is bubbled
Device refers to the container that bead is placed with equipped with liquid water and bottom, and air inlet is passed directly to the bottom of container by straight tube, and can
The bead contact for increasing disengagement area, finally by the gas of the close saturation of another pipeline discharge on liquid level.This humidification
The advantages of method is that equipment is simple, and technical process is easy, can arrive to obtain very high humidity in small flow, the disadvantage is that temperature and wet
Degree is difficult accurately to control, and when battery quick start live load is widely varied suddenly, humidification cannot synchronize response in time,
In addition, gas takes excessive liquid water out of after water container is bubbled when big flow, liter water container outlet liquid water is caused
Aggregation.
Utility model content
To overcome the problems, such as that fuel cell bubbling humidifier control temperature and humidity is inaccurate, the utility model provides one kind
Gas temperature and humidity can effectively be controlled by being bubbled humidifier.
The utility model solves the technical solution that technical problem uses are as follows: being bubbled humidifier includes air inlet pipe, heat exchanger tube, exposure
Reaction gas is introduced into closed container by gas head, electric heater and escape pipe, air inlet pipe, and closed container bottom is equipped with liquid, close
Container top is closed there are air, heat exchanger tube, aeration head and electric heater are completely disposed in liquid, and electric heater heats liquid, instead
Should gas exchanged heat by heat exchanger tube and liquid, reaction gas enters in liquid by aeration head, enters closed container top immediately
In the air in portion, the reaction gas after heat exchange humidification is discharged by escape pipe.
The utility model has the beneficial effects that
(1) reaction gas can be rapidly achieved the temperature and humidity of requirement by the utility model；
(2) the utility model is practical is cleverly bubbled humidifier using conventional device construction, and economy is good.
