Description

The condenser that is used for fuel cell

Technical field

The utility model is about a kind of condenser that is used for fuel-cell device, and it is particularly in order to solve the emission problem of fuel cell steam that produces in electrochemical reaction process.

Background technology

Fuel cell is a kind of chemical energy that will be stored in fuel and the oxidant is converted into electric energy by electrode reaction a TRT.The kind of fuel cell is quite a lot of now, can divide into according to the electrolyte property difference: five kinds of electrolytical fuel cells of difference such as alkaline fuel cell, phosphoric acid fuel cell, Proton Exchange Membrane Fuel Cells, molten carbonate fuel cell, solid-oxide fuel cell.

Although fuel cell is obtained some progress in recent years, aspect commercialization, still face huge technological challenge, comprise that its overall efficiency and power density are low, water management, heat management, microminiaturization and cost etc.

Present many fuel cells are to produce the water product after electrochemical reaction, and make other electronic building brick in the electronic system to be affected, therefore, how to handle this problem of water product, in the design of fuel cell system, be to be one of a kind of item that needs to be resolved hurrily.

Creator of the present utility model is because conventional fuel cell has necessity of improvement for the processing of water product, is urgently think to improve and create a kind of solution that can effectively solve the water product emission problem of fuel cell.

The utility model content

Main purpose of the present utility model is to provide a kind of condenser that is used for fuel-cell device, in order to the steam that fuel cell generated is condensed into water.

Another purpose of the present utility model is to provide a kind of condenser that is used for fuel-cell device, in order to catching the steam that fuel cell generates, and steam is limited in this condenser inside.

For reaching above-mentioned purpose, the utility model provides a kind of condenser that is used for fuel cell, comprising: a motor; One housing is for having the enclosed construction of an internal capacity room; An and spiral radiating piece, be arranged at this internal capacity room and be connected in this motor, and by this this spiral radiating piece of motor control rotation, make the drop be condensed in this spiral radiating piece surface can be caused the inner surface of this housing by this, and make the drop of inner surface of this housing be towed to the end of this internal capacity room by throwing.

The utility model condenser can be in order to be condensed into water with the steam that fuel-cell device generated, and the steam of being caught all is limited in condenser inside, and can not allow the steam that fuel-cell device generated be discharged arbitrarily, this is advantage of the present utility model place.

Be familiar with this skill personage and understand the purpose of this utility model, feature and effect for making, now by following specific embodiment, and cooperate appended graphic, to the utility model illustrate in detail as after.

The specific embodiment

Fig. 1 shows that the utility model is used for the outside drawing of the condenser of fuel cell.As shown in Fig. 1, the utility model condenser 1 comprises housing 10, motor 12 and spiral radiating piece 14.Its middle shell 10 is a kind of enclosed construction with internal capacity room 100, if with regard to the volume shape, housing 10 for example can adopt a housing with microscler cylindrical structure.

Fig. 2 shows that the utility model is used for the cross sectional side view of the condenser of fuel cell.Referring to shown in Figure 2, housing 10 has air inlet 102, exhaust outlet 104 and delivery port 106, and wherein air inlet 102 is arranged on the front end of housing 10, is connected to the outlet (figure does not show) of the gaseous state product of fuel-cell device in order to direct connection or caliber.Exhaust outlet 104 is arranged on the terminal top of housing 10, and delivery port 106 is arranged on the terminal bottom of housing 10.Moreover spiral radiating piece 14 is arranged at internal capacity room 100 and is connected in motor 12, and rotates spiral radiating piece 14 by motor 12 controls.Fig. 3 then further shows the integral outer appearance figure of spiral radiating piece 14.As shown in Figure 3, spiral radiating piece 14 has rotating shaft 140 and at least more than one blade 142.Wherein those blades 142 not only constitute a kind of sped structure body, and those blades 142 turn up the soil at interval and be arranged at rotating shaft 140, and a separate gap between the inner surface of the outer rim of those blades 142 and housing 10.And for example Fig. 1 and Fig. 2 are shown, and the utility model condenser 1 further comprises at least more than one outside radiating piece 20.Outside radiating piece 20 is linked to the outer surface of housing 10, and can adopt outward appearance radiating fin in the form of a ring.So, the utility model condenser 1 can carry out heat exchange by the outside radiating piece 20 and the Cryogenic air of outside, to promote the heat radiation and the condensation effect of condenser 1.

Then, the operating principle of the utility model condenser 1 being done one describes in detail.Now be example with the DMFC device, the high temperature that the DMFC device is generated and the steam of high humility enter to condenser 1 inside from air inlet 102, move with helical-like path in internal capacity room 100 along with the rotation of spiral radiating piece 14 then.After steam touches those blades 142, can become drop in spiral radiating piece 14 surface condensations because of the temperature difference, the spiral radiating piece 14 that is subjected to motor 12 fast driving then can be thrown the inner surface that causes housing 10 with drop, and this promptly is subjected to due to the action of centrifugal force.Next, the drop of the inner surface of housing 10 can be subjected to the passing of those blades 142 and be towed to the end of internal capacity room 100, accumulates condensate water then, flows out to the outside of condenser 1 again from delivery port 106.Certainly, the condensate water that is reclaimed can be utilized by fuel cell again.

In order to make the utility model condenser 1 have preferable condensation effect, the material of the housing 10 of condenser 1 for example can be used heat conducting material: metal material is made.In addition, being fit to use the fuel-cell device of the utility model condenser 1 can be single fuel cell or fuel cell pack (stack).

Another characteristic of the utility model are, the design of spiral radiating piece 14 can make the gaseous state product of fuel-cell device that long mobile route is arranged in the utility model condenser, allows the blade 142 of spiral radiating piece 14 have adequate time to carry out the water operation of condensing; Moreover, spiral radiating piece 14 be utilize centrifugal principle and and the inner surface of housing 10 between traction, the drop that comes effectively internal capacity room 100 to be generated everywhere compiles to the end of internal capacity room 100, therefore makes the utility model condenser form the speed very advantageous of condensate water.

Though the utility model discloses as above with specific embodiment; right its disclosed specific embodiment is not in order to limit the utility model; anyly be familiar with this skill person; in not breaking away from spirit and scope of the present utility model; when being used for a variety of modifications and variations; its change of doing all belongs to category of the present utility model with retouching, and protection domain of the present utility model is as the criterion when looking the scope that claim defines.
