Description

A kind of humidifying device
Technical field
The utility model relates to a kind of humidifying device.
Background technology
Need carry out humidification to material in a lot of fields.
For example, membrane electrode is the core component of Proton Exchange Membrane Fuel Cells, and as shown in Figure 1, membrane electrode is made up of anode gas diffusion layer A, anode catalyst layer B, proton exchange membrane C, cathode catalysis layer D and cathode gas diffusion layer E.Membrane electrode is the place that electrochemical reaction takes place, and enters into anode catalyst layer at anode fuel by anode gas diffusion layer during reaction, and is oxidized under catalyst action; Enter cathode catalysis layer as the oxygen or the air of cathode reactant by cathode gas diffusion layer at negative electrode, generated product water by the cathod catalyst reduction.
Adopting hydrogen is fuel, and the air that contains oxygen is in the Proton Exchange Membrane Fuel Cells of oxidant, and at anode, hydrogen generates hydrogen cation (or being proton) under catalyst action, and proton exchange membrane helps the hydrogen cation to move to negative electrode from anode.At negative electrode, oxygen obtains electronics on catalyst surface, forms anion, and moves the hydrogen cation reaction of coming with the anode region, generates product water, and the product water of generation is discharged with reaction end gas by gas diffusion layers.In addition, battery also produces a part of heat in course of reaction, and this part heat is also discharged with reaction end gas.
As mentioned above, Proton Exchange Membrane Fuel Cells is when work, and the proton in the battery will conduct by proton exchange membrane.And the proton exchange membrane conductive process needs water and just can finish, because have only the proton of aquation just can freely pass proton exchange membrane, arrives the electrode cathode end from the electrode anode end and participates in electrochemical reaction.Therefore, can work continuously, must make the proton exchange membrane in the Proton Exchange Membrane Fuel Cells keep moistening in order to guarantee Proton Exchange Membrane Fuel Cells.Generally need carry out humidification, so that the proton exchange membrane maintenance is moistening to the reacting gas that enters battery.
The electricity of proton exchange membrane is led with its water content closely related, and the water content of film plays crucial effects to the performance and the life-span of Proton Exchange Membrane Fuel Cells.If the water content of film is too high, the existence of a large amount of aqueous waters can cause oxygen transfer speed reduction in the cathode gas diffusion layer, increases concentration polarization, reduces battery performance; If the water content of film is low excessively, then film increases the resistance of proton, even can't finish electrochemical reaction.So adding the moisture of proton exchange membrane wants suitably.
CN1459882A discloses a kind of humidifying device, and as shown in Figure 2, this humidifying device comprises shell 1, inner bag 2, motor 3; Shell 1 is a column, the both sides of one end are respectively equipped with humid gas outlet 4, humid gas import 5, the both sides of its other end are respectively equipped with dry gas import 6, dry gas outlet 7, wherein humid gas outlet 4 is relative with dry gas import 6, it is 7 relative that humid gas import 5 and dry gas export, and the other end central authorities of shell are provided with centre bore 8; Inner bag 2 is arranged in the shell 1, it is and shell 1 corresponding column, the both sides of inner bag 2 one ends are respectively equipped with shell humid gas outlet 4, humid gas import 5 corresponding two humid gas and go out/enter the mouth 9, the both sides of inner bag 2 other ends are respectively equipped with and export 7 corresponding dry gas with shell dry gas import 6, dry gas and go out/enter the mouth 10, be provided with dividing plate 11 in the middle of the described inner bag 2, this dividing plate 11 is divided into equal two parts with inner bag 2, is provided with hydrophilic porous filler 12 in two parts of inner bag 2; Described motor 3 is positioned at an end that is provided with centre bore 8 of shell 1, and its power transmission shaft 13 passes centre bore 8, and fixedlys connected with inner bag 2.
The course of work of this device is as follows: the humid gas of outer casing bottom is exported the gas feed 23 of 4 external Proton Exchange Membrane Fuel Cellss 22, with the gas vent 21 of the humid gas import 5 external Proton Exchange Membrane Fuel Cellss 22 of outer casing bottom; After hot and humid gas that Proton Exchange Membrane Fuel Cells is discharged is entered by the humid gas import 5 of humidifying device, part along inner bag 2 is advanced, the filler of being located in the inner bag 2 12 can allow gas make moisture and heat dam to get off by dry gas outlet 7 discharges, after the moisture in the filler 12 reaches capacity state, motor 3 drives inner bag 2 Rotate 180 degree, the two-part location swap of inner bag 2, after dry gas enters from the dry gas import 6 of humidifying device, the part by humidification along inner bag 2 is advanced, just in time meet, become humid gas and come out to enter Proton Exchange Membrane Fuel Cells from humid gas outlet 4 with moisture and the heat that gets off that dam.This device is realized function to the proton exchange membrane humidification by the moisture that generates in the recycling Proton Exchange Membrane Fuel Cells running and heat, do not need additionaling power equipment, do not need to this humidifying device supply pure water yet, thereby saved the energy, reduced the operating cost of Proton Exchange Membrane Fuel Cells.But also there is following shortcoming in this device: (1) is filled in the inner bag 2 owing to filler 12, filler 12 is compacted under the effect of gravity, so gas is difficult for by filler 12, thereby influenced the circulation of gas, cause dry gas from inner bag 2, not discharge fully, humid gas can not be fed to the Proton Exchange Membrane Fuel Cells from inner bag 2 continuously, thereby has influenced the humidification effect of this humidifying device, has reduced the service behaviour of Proton Exchange Membrane Fuel Cells.(2) because gas just flows to the other end of shell from an end of shell, so gas flow is shorter, under the bigger situation of gas flow rate, filler 12 can't fully absorb the moisture in the humid gas, and the also abundant moisture in the dry load 12 of dry gas causes the Humidifying of gas deleterious.(3) since this device just by with inner bag 2 at interval the mode of certain hour Rotate 180 degree to gas humidification, and the instrument of the humidity of the gas of not control process humidification, so can't accurately control the humidity of the gas that enters Proton Exchange Membrane Fuel Cells, also just can't accurately control the water content of proton exchange membrane.
