Description
Technical field
The utility model relates to humidifier technical field more particularly to a kind of humidifiers for fuel cell.
Background technique
Fuel cell be a kind of cleaning, efficiently, the power generator of long-life.Compared with conventional generation technology, fuel electricity
Pond efficiency, safety, reliability, flexibility, spatter property, in terms of have very big advantage, application prospect is very
It is wide.In the operational process of fuel cell, gas, that is, air inlet humid control into fuel cell is most important.To combustion
When the air inlet of material battery is controlled, usually realized by humidifier.
In current practice, for fuel cell air inlet humidification humidifier there are mainly two types of, one is membrane humidifier,
It is humidified by diffusion couple air inlet of the moisture in film；Another kind is enthalpy wheel humidifier, is humidified by enthalpy wheel.
Membrane humidifier has the characteristics that compact-sized, low pressure drop, typical structure include wet plate, polymer film, diffusion layer
And dry plate, wherein the flow channel on dry plate is used for circulation and the humidification of dry gas, has humidification channel on wet plate.Membrane material is saturating
Water but airtight, its side is contacted with wet plate, and other side is the diffusion layer made of elasticity, conductive, gas permeable material.But
There is sealing and pressure-bearing in membrane humidifier, because polymer film meets water-swellable, repeatedly swelling-receipts of the film between dry-hygrometric state
Contracting will lead to and be detached from sealing surface, to leak；In addition, polymer film is organic material, it is easily deformable, and resistance to pressure energy
Power is poor, may rupture under the influence of air pressure in use.
Enthalpy wheel humidifier is to carry out the humidification gain of heat using the air inlet that enthalpy wheel is fuel cell, and core component is by motor band
Dynamic porous ceramics runner (i.e. enthalpy wheel).Its working principle is the exhaust (heat of the humidity close to 100%, moisture) of fuel cell
Into enthalpy wheel humidifier, enthalpy wheel absorbs the heat and moisture in exhaust, is stored in its porous structure.When fresh air enters enthalpy
When wheel, since fresh air relative humidity is low, the moisture in enthalpy wheel is evaporated and is taken away, to complete to add air inlet
It is wet, while air inlet is also improved due to absorbing heat, temperature.When enthalpy wheel humidifier is rotated with certain speed, enthalpy wheel is successively
(humidification process) and absorption heat and moisture (moisture absorption process) from fuel cell exhaust are heated by being humidified to air inlet, that is, is increased
Wet-moisture absorption process.Enthalpy wheel humidifier is at low cost, the service life is long, structure is simple, easily fabricated, heat recovery rate is high, humidification moisture
It is easy the advantages that adjusting.However, enthalpy wheel humidifier has the following problems: (1) ceramic density is big, will increase mass of system and rotation
The power consumption of motor, it is especially on automobile in application, more sensitive to weight and power consumption (efficiency)；(2) ceramics abrasion is asked
Topic is serious, the abrasion between ceramic enthalpy wheel and shell, and the gap that will lead between enthalpy wheel and shell increases, this will lead to fuel electricity
The exhaust in pond is mixed into fresh air, oxygen concentration in air inlet after reduction humidification；(3) frictional resistance of the ceramics as humidification enthalpy wheel
Larger, power consumption and noise are larger, influence the service life of humidifier.Since there are these problems, enthalpy wheel humidifier cannot expire well
High efficiency and the longtime running requirement of sufficient fuel cell system.
Summary of the invention
The purpose of this utility model is to solve current humidifier presence to be easy to happen leakage, easily deformable, voltage endurance capability
Difference, rupture may occur under the influence of air pressure in use, humidification can be reduced after oxygen concentration and power consumption in air inlet,
The technical problem that noise is larger and the service life is shorter provides a kind of humidifier for fuel cell.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of humidifier for fuel cell comprising humidifier ontology, the first two-position four way change valve, the two or two
Four-way reversing valve and PLC controller, in which: the humidifier ontology includes the first cavity and the second cavity, the first cavity and the
Two inside cavities are honeycomb body structure；The control terminal of PLC controller respectively with the first two-position four way change valve and the two or two
The control terminal of four-way reversing valve connects；The P mouth of first two-position four way change valve is connect with dry gas source, the first two-position four way change valve
T mouth connect with exhaust gas containing box, the first opening of the A mouth of the first two-position four way change valve and the first cavity connects, the one or two
The B mouth of position and four-way reversing valve and the first opening of the second cavity connect；P mouth and the fuel cell of second two-position four way change valve
Damp exit connection, the T mouth of the second two-position four way change valve are connect with the moisture import of fuel cell, the commutation of the second two-position four-way
The B mouth of valve and the second opening of the first cavity connect, and the A mouth of the second two-position four way change valve connects with the second opening of the second cavity
It connects.
Optionally, the material of the honeycomb body structure is ceramics or cordierite.
Optionally, the fuel cell is Proton Exchange Membrane Fuel Cells.
Optionally, the dry gas source provides air or hydrogen.
The beneficial effects of the utility model are:
By the humidifier ontology of setting four-way electromagnetic reversing valve, PLC controller and the first cavity and the second cavity, and will
The inside of first cavity and the second cavity is set as honeycomb body structure, and controls the first two-position four-way by PLC controller and change
To the commutation opportunity of valve and the second two-position four way change valve, a kind of humidification different from membrane humidifier and enthalpy wheel humidifier is provided
Device, humidifier provided by the utility model do not need rotary electric machine, do not have noise, Bu Huifa without moving parts, humidification
Raw leakage.Therefore, compared with the background art, the utility model, which has, will not leak, be not easy to deform, voltage endurance capability is good,
Use process will not rupture, will not influence humidification after oxygen concentration and power consumption in air inlet, long without noise and service life
The advantages that.
